A new subspecies of Papasula booby is described from fossil remains collected in the Mascarene Islands of Mauritius and Rodrigues, southwestern Indian Ocean. The Mascarene Booby Papasula abbotti nelsoni ssp. nov., larger than nominate Abbott’s Booby P. a. abbotti from Christmas Island, northeast Indian Ocean, was approximately the same size as the extinct Hiva Oa Booby P. a. costelloi from the Marquesas in the Eastern Pacific. Mentioned in early accounts of Mauritius in 1668 and in 1725–26 and 1761 on Rodrigues, the Mascarene booby became extinct by the end of the 18th century. Members of another isolated but now extirpated population of Papasula abbotti from Assumption Island in the Seychelles Archipelago, the island from which the type specimen was collected, are identical to extant Christmas Island birds in size and colouration and discussed in detail herein.

Genus Papasula Olson and Warheit, 1988 Papasula abbotti Olson & Warheit, 1988, p. 10 Type (by monotypy) Osteological diagnosis and comparison. The following osteological characters in combination characterize the genus Papasula. The fossil specimens are much larger than those of species in most other marine bird genera occurring in the Mascarenes, including those in Oceanitidae, Phaethontidae, Laridae, Stercorariidae, and in all Procellariidae except Macronectes giganteus. Papasula abbotti is smaller than M. giganteus and all species of Diomedeidae. It differs from similar-sized Fregata ariel and F. minor as follows. Coracoid: smaller, more gracile, and processus lateralis much less extensive. Sternum: larger; in lateral view, sulcus articularis coracoideus bordered with a much larger labrum interna and tuberculum labri externa; in dorsal view, foramina pneumatici larger, much more extensive. Humerus: more gracile, much thinner in the shaft and particularly lacks a sharply angular crista deltopectoralis. Ulna: much smaller; cotyla dorsalis larger and directed distad; impressio brachialis much more excavated; papillae remigales much less pronounced. Tarsometatarsus: most notably by much larger size, extremely reduced in length and width in Fregata, and sulcus extensorius much more deeply excavated. The Papasula material described herein is further assigned to Sulidae by the characters identified in Olson & Warheit (1988), Steadman et al. (1988), and van Tets et al. (1988), who also mentioned diagnostic characters of the cranial and other parts of the postcranial skeleton not discussed here.

Papasula abbotti, Cheke & Hume, 2008, p.47; Hume, 2013, p.216. Papasula sp., Hume, 2017, p.84. Holotype: Left humerus UMZC 262.AA (Figs. 4b, 5b) Measurements: (see Table 2). Type Locality: Mare aux Songes, southeast Mauritius (20826051, 200 S; 57841023, 500 E) Distribution: Mauritius and Rodrigues, Mascarene Islands. Etymology: Named after British ornithologist Joseph Bryan Nelson (14 March 1932 – 29 June 2015), who first recognised the presence of a Papasula booby on the Mascarenes, and whose ground-breaking studies on sulids and especially Papasula abbotti are still relevant today. Paratype: Left ulna UMZC 262.AA (almost certainly associated with Holotype), Mare aux Songes, southeast Mauritius (Figs. 6c, 6f). Referred fossil material: All collected from unspecified caves on the Plaine Corail, Rodrigues: coracoid NHMUK PV A9076 (Ld) (Fig. 2); cranial fragment of sternum NHMUK PV A9076 (Fig. 3); humerus (Lp) NHMUK PV A9049 (Figs. 4a, 5a); ulna MNHN 6574 (Rd); NHMUK PV A9076 (Rd) (Fig. 6); tarsometatarsus UMZC 995 (R) (Figs. 7b, 7c). Diagnosis: As for genus. Chronology: No dates are available from bird remains from the 19th century Mare aux Songes (MAS) collections (Basin 0), but 14C dates exist for MAS fossil remains of endemic giant tortoises Cylindraspis ssp., which became extinct c.1730, that were excavated from the same horizon as the Mascarene booby elements (Hume et al. 2021). The dates range from ca. 1260 to 1830 YBP (Burleigh & Arnold 1986). On Rodrigues, a partial humerus of the endemic owl Otus murivorus (Milne-Edwards, 1873), collected from 60–75 cm below surface in Caverne Dora on the Plain Corail, produced a radiocarbon age of 2850 ± 30 with a calibrated age range of 3060–2870 YBP (Burney et al. 2015). This suggests very low sedimentation rates in the late Holocene (Hume 2013; Burney et al. 2015). Although the precise cave from which P. a. nelsoni was collected is unknown, many of the caves on the Plaine Corail have depositional environments similar to that of Caverne Dora (Hume 2005, 2013). Description and comparison: Papasula a. nelsoni ssp. nov. differs from Papasula a. abbotti in being larger in all known elements (Appendix 1, Tables 1-4) and by the following diagnostic characters: Coracoid (Fig. 2b; table 1). In mediodorsal view, the proximal end is missing the tuberculum brachiale and facies articularis clavicularis, and sternally is missing the processus lateralis from the lateral point of labrum internum to margo caudolateralis on distal end. Nevertheless, it differs from P. a. abbotti on the dorsal surface by, impressio lig. acrocoracohumeralis broader and deeper; process on labrum externum larger, more prominent, with extension to distal corner of angulus lateralis more deeply excavated; in ventral aspect, facies articularis sternalis deeper, extending further laterad; in lateral aspect, facies articularis humeralis larger and wider extending further proximally. Sternum (Fig. 3; table 1). Only a small cranial fragment is preserved that includes two pairs of cranial foramina pneumatici and a single row (right side) of foramina pneumatici that follow the sulcus medianus sterni; it is missing the entire carina sterni and posterior part to processus craniolateralis including all processus costales. Differs from P. a. abbotti by, in dorsal aspect, tuberculum labri externa with more pronounced ridge on lateral edge; in lateral aspect, labrum interna and tuberculum labri externa larger, with sulcus articularis coracoideus deeper, creating a more pronounced undercutting of labrum interna; in ventral aspect, two cranial foramina pneumatici larger. Humerus (Figs. 4a, 4b, 5a, 5b; table 2). Holotype (UMZC 262.AA), collected on Mauritius, is complete with no erosional damage, whereas the Rodrigues specimen (NHMUK PV A9049) lacks around 66% of the distal end and much of the crista deltopectoralis. Differs from Papasula a. abbotti by, on caudal surface, tuberculum dorsale larger, more oval, and more rugose on distal surface; tuberculum ventrale larger and more robust, projecting more caudad and extending further mediocaudad; caput humeri more bulbous; incisura capitis more deeply excavated; margo caudalis more clearly defined proximally where it connects laterad to base of tuberculum ventrale; crus ventrale fossa more prominent proximally, especially at base of tuberculum ventrale; crista bicipitalis more convex without rightangled connection to shaft distally; fossa pneumotricipitalis larger, more deeply excavated with medial foramen pneumaticum much larger; sulcus humerotricipitalis more deeply incised, terminating in a sharp angle proximally; sulcus scapulotricipitalis more deeply incised, extending further proximally well beyond proximal level of sulcus humerotricipitalis; processus flexorius blunt, rounded distally, not angular; on cranial surface, sulcus lig. transversus deeply excavated medially, shallower laterally; crista bicipitalis more bulbous, without small distal crista; fossa m. brachialis more excavated; fossa olecrani larger; processus flexorius smaller, directed less medially. Ulna (Figs. 6c, 6f; table 3). Paratype (UMZC 262.AA), collected on Mauritius with holotype, is complete with no erosional damage, whereas the Rodrigues specimen (NHMUK PV A9076)is missing around 85% of the proximal end. Differs from P. a. abbotti in being longer, overall more robust; shaft less straight, more curved craniocaudally; in dorsal aspect, distal end more expanded; proximal pneumatic foramen larger; in ventral aspect, impressio brachialis more deeply excavated proximally; papillae remigales ventralis more prominent; sulcus intercondylaris deeper; foramen pneumaticum situated above sulcus intercondylaris and undercutting condylus dorsalis larger; presence of second foramen pneumaticum situated proximally on tuberculum carpale (absent in P. a. abbotti); depressio radialis more deeply excavated; in cranial aspect, cotyla ventralis narrower, more pointed; pneumatic foramen between condylus ventralis ulnaris and tuberculum carpale larger. Tarsometatarsus (Figs. 7b, 7c; table 4). Specimen missing crista medialis hypotarsi and plantar surface of trochlea metatarsi II and IV. Differs from P. a. abbotti by, in dorsal aspect, sulcus extensorius deeper proximally; incisura intertrochlearis lateralis and incisura intertrochlearis medialis slightly wider; tuberositas m. tibialis cranialis more marked, extending beyond proximal tip of lateral foramina vascularia proximalia; in plantar aspect, crista plantares lateralis more pronounced and lacking small foramen pneumaticum distal to crista lateralis hypotarsi; foramen vasculare distale much larger; wider and deeper sulcus on trochlea metatarsi III;medial surface of trochlea metatarsi IV more excavated, creating a pronounced crista extending proximal to crista plantares medialis; on proximal end, larger, otherwise similar to P. a. abbotti. The specimen figured (Fig. 8) in Milne-Edwards (1873) is the same specimen, but since that drawing’s execution, further damaged has occurred. For example, the crista medialis hypotarsi is now missing. Differs from P. a. costelloi by, in dorsal aspect, trochlea metatarsi II extends less distally; trochlea metatarsi III with shallower sulcus on dorsal surface; foramen vasculare distale smaller and situated more proximad; in plantar aspect, crista plantares lateralis more pronounced; foramen vasculare distale larger; fossa supratrochlearis more deeply excavated, especially where it connects to foramen vasculare distale medially.

International audience; We provide an up-to-date catalogue of the Coccomorpha Rubsaamen, 1899 of New Caledonia based on studies of collected and curated specimens and on the literature. One hundred and eighteen species (118) in ten families have been recorded to date, in 70 genera. Five of the genera (7.2%) are endemic, belonging to Asterolecaniidae Berlese, 1898 (Oacoccus Williams, 2007), Eriococcidae Cockerell, 1899 (Chazeauana Matile-Ferrero, 1988, Choneochiton Hodgson, 2014) and Monophlebidae Maskell, 1880 (Insulococcus Bhatti, 1991, Tessarobelus Montrouzier, 1864). Twenty-nine (29) species are endemic to New Caledonia, giving a rate of endemism of 24.6%. Most of the species are apparently human-assisted introductions. We provide here first records from New Caledonia for ten (10) species: Aulacaspis rosarum Borchsenius, 1858; Chrysomphalus pinnulifer (Maskell, 1891); Diaspis echinocacti (Bouche, 1833); Fiorinia phantasma (Cockerell & Robinson, 1915); Labidaspis myersi Green, 1929; Palmicultor browni (Williams, 1960); Poliaspoides formosana (Takahashi, 1930); Pseudococcus gilbertensis Beardsley, 1966; Pseudococcus orchidicola Takahashi, 1939 and Rhizoecus cacticans (Hambleton, 1946). Despite two introduction attempts for the biological control of weedy cactus, Hypogeococcus festerianus (Lizer y Trelles, 1942) is still considered absent from New Caledonia. Literature records of five species are shown to be erroneous: Dactylopius tomentosus (Lamarck, 1801); Dysmicoccus cocotis (Maskell, 1890); Lindingaspis buxtoni (Laing, 1927); Nipaecoccus filamentosus (Cockerell, 1893) and Clavaspis herculeana (Cockerell & Hadden, in Doane & Hadden, 1909), which are therefore considered absent from New Caledonia.

We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data. Fil: Somenzari, Marina.

Sulidae Morus capensis (VAG): breeds on the coast of southern Africa and in Namibia. It overwinters along the African coast west to the Gulf of Guinea,in eastern Mozambique, and exceptionally as far as Kenya. Most adult individuals remain in the waters close to the colony after breeding. Young individuals migrate north to the Gulf of Guinea (Carboneras, 1992). The species occurs occasionally in Brazil outside the coast of RS (Vooren, 2004) and SC (Olmos, 1997). Morus serrator (VAG): breeds in the east coast of Australia, Tasmania and New Zealand and there is also a small colony on Norfolk Island. It overwinters in waters adjacent to the east coast and in western Australia. Adults remain in areas around the colony, while immature individuals are more dispersive (Carboneras, 1992).

The chewing lice (Insecta: Phthiraptera: Amblycera and Ischnocera) of Mexico have been little studied and many publications include isolated records. This paper summarizes current knowledge of chewing lice recorded from Mexico resulting from an exhaustive search of the literature published from 1866 to 2017. We found 342 louse species associated with 206 bird and 28 mammal species. As a result, we provide a checklist of the chewing lice recorded from Mexico, including a host-parasite list and their geographical distribution within the country.

LEUCOCARBO STEWARTI FOVEAUX SHAG PHALACROCORAX STEWARTI OGILVIE-GRANT, 1898 Diagnosis. A species of Leucocarbo most closely related to L. chalconotus and L. onslowi but distinguished from these species by the plumage characters and allometries outlined in Table 1. Distribution. Restricted to Foveaux Strait and Stewart (based on historical museum skins and modern specimens). Leucocarbo stewarti bones have been recorded from Late Quaternary and archaeological deposits from this region (e.g., Worthy, 1998 b). Rare archaeological and modern beach wrecks in Otago (Rawlence et al., 2014, 2015). The type locality of Gracalus chalconotus G. R. Gray, 1845 is currently considered to be Otago Province. However, the Otago Province included Southland and Foveaux Strait until 1861. We consider that the likely type locality is in fact Karitane, where the type specimen was likely collected by Percy Earl in 1843 (Scofield et al., 2012). Although Earl spent the majority of his time at Karitane, Earl only travelled as far south as the Clutha River, which is still within the range of the Otago lineage, but may have had Maori��� collect for him elsewhere (Scofield et al., 2012). The type locality of Phalacrocorax stewarti Ogilvie-Grant, 1898 is Bluff (a town in Southland), where specimens were collected by Baron A. von Hugel on 13 February 1875 (Ogilvie-Grant, 1898 contra Stewart, Gill et al., 2010). Ogilvie-Grant (1898) designated three syntypes (NHMUK 1880.5. 3.1, 1880.5. 3.2, and 1880.5.3.6), all pied morphs. Warren (1966) only segregated and listed the syntype 1880.5. 3.6 for inclusion in the NHMUK type collection, but this action does not affect the status of the remaining unselected syntypes. NHMUK 1880.5. 3.1 and 1880.5. 3.2 are currently labelled as Phalacrocorax campbelli huttoni (reflecting a previous taxonomic treatment) and we did not attempt to obtain DNA from them. As all three syntypes were collected from the same locality at the same time, and 1880.5. 3.6 clusters with individuals from Foveaux Strait (Figs. 4, 6, Appendix 1), we refer 1880.5. 3.1 and 1880.5. 3.2 to L. stewarti. PLUMAGE EVOLUTION AND PHYLOGEOGRAPHICAL CONSIDERATIONS Phylogenetic relationships amongst the Otago, Foveaux, and Chatham shags suggest a geologically recent colonization of the Chatham Islands from a mainland South source population, consistent with numerous phylogeographical studies from the region (Goldberg, Trewick & Paterson, 2008; Mitchell et al., 2014; Wood et al., 2014). All New Zealand /sub-Antarctic Leucocarbo shags have subtle differences in plumage patterns (e.g. scapulars, prenuptial head crest; Marchant & Higgins, 1990). However, the Otago and Foveaux shags are the only Leucocarbo species with adult dimorphic plumage patterns ��� pied (black and white) and bronze (wholly dark) (Figs 1, 2). Given our phylogeny (Fig. 4), we can hypothesize that the common ancestor of L. chalconotus, L. onslowi, and L. stewarti evolved dimorphic plumage. Divergence between L. chalconotus and L. stewarti is probably a result of isolation in refugia during the Pleistocene glacial cycles, when the majority of offshore islands and rock stacks in Foveaux Strait and around Stewart favoured by L. stewarti were landlocked because of lower sea levels. The Chatham Islands were colonized by progenitors of L. chalconotus, which evolved into L. onslowi. Colonization was either by pied L. chalconotus individuals or a mixture of pied and bronze individuals, with subsequent genetic drift resulting in the loss of the bronze morph. Given the lack of well-supported structure within the Otago shag we cannot definitively test evolutionary scenarios for the bronze morph, but it seems much simpler to assume that the bronze morph evolved once and was subsequently lost in L. onslowi than that it evolved independently twice (in the Otago shag and in the Foveaux shag). CONSERVATION IMPLICATIONS Prior to our splitting of the Stewart shag into two distinct taxa, the International Union for Conservation of Nature Red List categorized this species as Vulnerable with population estimates varying between 1600 and 1800 pairs to fewer than 5000 birds and threats including fisheries interactions and nest disturbance (Birdlife International, 2012). Given their revised status, Otago and Foveaux shags should be managed separately, with further population-genetic research to determine levels of genetic variation at faster-evolving nuclear loci and potential inbreeding (e.g. Calderon et al., 2014). The Foveaux shag has been characterized by population and range stability, in contrast to the Otago shag that has undergone a pronounced population bottleneck and range contraction (Rawlence et al., 2015). Although the Otago shag has recolonized part of its former distribution since the European era, its population size continues to decline (Lalas & Perriman, 2009)., Published as part of Nicolas J.

Zanthoxylum alatum The Flora Indica description of this plant (Roxburgh 1832b) makes direct reference to Hardwicke���s unnamed Zanthoxylum (as ���Xanthoxylum���), of which there is a drawing in the Natural History Museum set (no. 39) and a similar pair in the British Library (Vol. XIV nos. 7 and 8). Roxburgh���s name, however, was cited by Wallich in his Numerical List, rendering it a superfluous, and illegitimate, renaming of Z. acanthopodium DC. Thus Roxburgh���s name becomes an illegitimate later homonym. Hartley (1966: 211) proposed Roxburgh icon 1916 as the lectotype of Z. alatum Roxb. but he did not state which set of drawings (Kew or Calcutta) he was referring to. I therefore clarify the issue by proposing the Kew copy below., Published as part of Turner, Ian M., 2015, The botanical legacy of Thomas Hardwicke's journey to Srinagar in 1796, pp. 1-25 in European Journal of Taxonomy 108 on page 21, DOI: 10.5852/ejt.2015.108, http://zenodo.org/record/3779322, {"references":["Roxburgh W. 1832 b.

International audience; Blood parasites of the sub-genus Haemoproteus have been reported in seabirds, in particular in species in the Suliformes order. These parasites are transmitted by hippoboscid flies of the genus Olfersia; strong specificity has been suggested between the vector and its vertebrate host. We investigated the prevalence of Haemoproteus infection in Suliformes and hippoboscid flies in two oceanic islands of the Western Indian Ocean: Europa and Tromelin. In total, 209 blood samples were collected from great frigatebirds (Fregata minor), masked boobies (Sula dactylatra) and red-footed boobies (Sula sula). Forty-one hippoboscid flies were also collected from birds. Seventeen frigatebirds and one fly collected on Europa tested positive for the presence of Haemoproteus parasites by polymerase chain reaction. Phylogenetic analyses based on partial sequences of the Cytochrome b gene showed that parasites were closely related to Haemoproteus iwa reported from frigatebirds in the Pacific Ocean and in the Caribbean. Plasmodium was also detected in a frigatebird on Europa; however, its placement on the phylogenetic tree could not be resolved. We provide strong support for transmission of blood parasites in seabirds in the Western Indian Ocean and suggest that migrations between the Pacific and the Indian oceans could favor the large-scale distribution of Haemoproteus iwa in frigatebird populations.

International audience; Presented here is a new species of a cormorant-like bird, assigned to ?Borvocarbo tardatus n.sp., from the Early Miocene of the locality Rauscherod in Southern Germany. The preserved bones, a tibiotarsus, fragmentary ulna and radius, are compared in detail to those of fossil and extant taxa of phalacrocoracoids. Provided that the generic affiliation is confirmed when additional material is discovered, the new species is the stratigraphically youngest evidence and representative of the genus Borvocarbo.

Limnofregata hasegawai, new species (Figs. 5–7) Holotype: GMNH PV 170, skull and mandible with quadrates, lacrimals, palatines, atlas, axis, and cervical vertebrae 3–7 (Fig. 5). Color brownish black. The skull is preserved in right dorso­lateral view with the mandible and right quadrate still in articulation. The left quadrate has been displaced and lies upside­down, with the mandibular articulation visible along the edge of the left orbit. The lacrimals are still nearly in articulation with the frontals, the right palatine is exposed but neither pterygoid is visible. Locality: Smith Hollow Quarry, Lewis Ranch (Locality B of Grande and Buchheim, 1994), Lincoln County, Wyoming. Horizon: Said to have been collected " 2–3 m " from Referred Specimen 1 of L. azygosterno n (GMNH PV 167). Presumably this distance is intended as vertical as the matrix and the coloration of the bone (blackish vs. brown) are different. Fossil Butte Member of the Green River Formation, late early Eocene. Etymology: To our esteemed colleague and friend Yoshikazu Hasegawa of the Gunma Museum of Natural History in recognition of his many contributions to vertebrate paleontology. Diagnosis: Much larger than L. azygosternon. Rostrum proportionately much longer, 1.6 times as long as the cranium, vs. 1.4 in L. azygosternon. Measurements (mm) of holotype: Measurements that are comparable to those published for Limnofregata azygosternon appear in Table 2. Additional measurements are: Cranium: width at nasofrontal hinge, 16.8. Lacrimal: length, 17.1. Quadrate: length of articulation with mandible (left), 15.8. Atlas: width 11.9. Axis: width 13.1. Cervical vertebra 3: length, 16.1. Cervical vertebra 5: length, 22.8. Paratype 1: FMNH PA 719, complete skull and mandible with left quadrate, both lacrimals and pterygoids, assorted sclerotic plates, atlas, axis, and cervical vertebra 3 (Fig. 6). The skull is preserved in dorsal and partial left lateral view with the entire left quadratojugal bar visible. The ventral surface of the mandible can be seen in its entirety.

Locality: Warfield Fossil Quarries at Warfield Springs (NW 1 / 4, Sec. 5, T 19 N, R 117 W; locality K of Grande and Buchheim, 1994), ca. 14 km SW of Kemmerer, Lincoln County, Wyoming. Horizon: F­ 2 facies equivalent, Fossil Butte Member of the Green River Formation, late early Eocene. The specimen is from a 1.5 m thick layer of precipitated limestone overlying a 30–45 cm thick layer of bluish shale. Measurements: See Table 1. Description: As in L. azygosternon the nostril is long and open, the posteriormost corner being about 1 cm anterior to the naso­frontal hinge. The anterior margin can now be clearly discerned as extending nearly to the premaxillary symphysis. The configuration of the quadrate in ventral view in Limnofregata shows some distinctive features. In Phaethon the medial and lateral condyles are in the same transverse plane with practically no development of a posterior condyle. In Fregata, the medial condyle extends posterolaterally as a more constricted crest, which then bends at nearly a right angle to the lateral condyle, the bend forming a rather weak posterior condyle with a deep depression anterior to it. The configuration in the Sulidae is more complex, with the posterior condyle completely separate from the medial condyle. Limnofregata is most similar to Fregata, with the medial condyle forming a long rolling crest with only an incipient posterior condyle and the lateral condyle is only slightly angled off of the long axis of the articular surface. The depression seen in Fregata is shallower in Limnofregata. The pterygoids are relatively much longer in Limnofregata than in Fregata, with slightly curved rather than straight shafts that appear to be terete, without the flattened surfaces seen in Fregata or the Sulidae. They are quite unlike the very long, straight, and slender pterygoids in Phaethon. The mandibular articulations are much heavier in Limnofregata than in Fregata, the rami much thicker and deeper, and the mandibular symphysis shorter. In the ventral view afforded by the paratypical skull of L. hasegawai, the internal processes of the articulations are shorter, thicker, and much less distinctly set off from the heavy proximal portion of the rami than in Fregata. The one visible lacrimal in the holotype of L. azygosternon is partially obscured and was misinterpreted in the original description. The entire structure is beautifully revealed in paratype FMNH PA 719 of L. hasegawai in which both lacrimals are preserved with the entire external surface exposed (Fig 6). The corpus of the bone that articulates with the cranium is much larger than in Fregata, with the posterior portion broad and truncated. There are two small pneumatic foramina in the corpus, just anterior to the descending process. The descending process is very long and slender, with a very small expansion on the posterior margin about 2 / 3 the distance to the ventral extremity. The lacrimal in Fregata is very different, with a small, nonpneumatic corpus and a greatly expanded, inflated descending process that bears a single pneumatic foramen. The postcranial specimen of L. hasegawai is not in particularly good condition, but has the pelvis preserved in dorsal view and the thoracic vertebrae are better preserved than in the holotype of Limnofregata azygosternon. These do not differ greatly from those in Fregata. The specimen confirms that the distinctive notch in the posterior margin of the innominate bone in the area of fusion of the ischim and ilium (Olson, 1977: 15) is the normal condition. As in the holotype of L. azygosternon, the pygostyle is missing, suggesting that it may have floated away with the presumably enlarged rectrices. Size in Limnofregata. The seven available specimens now assigned to L. azygosternon are remarkably homogeneous in size and those for which comparable length measurements are available are practically identical (Table 1), especially given the variation induced by crushing and other vicissitudes of preservation. In the two skulls of L. hasegawai such factors of preservation have doubtless contributed to inaccuracies in the measurements of the cranium and rostrum. For example, in the paratype FMNH PA 719, the skull is broken across the nasofrontal hinge and the anterior margin of the cranium has been shoved under the posterior margin of the rostrum perhaps as much as 6 mm. On the other hand, the length measurements of the two known mandibles of L. hasegawai and in the holotype of L. azygosternon are unequivocal. The two mandibles of L hasegawai are identical in length and are 20 % larger than in the holotype of L. azygosternon. The postcranial paratype of L hasegawai basically agrees in size, as the femur is 17 % larger and the pelvis 20 % larger than in L. azygosternon. The tibiotarsus seems disproportionately small, however, as it is only 7 % larger. The same appears to apply within modern frigatebirds, however, as the tibiotarsus of the largest species, F. m i n o r, is proportionately smaller than in F. a r i e l, the smallest species (Table 3). The differences in size between L. azygosternon and L. hasegawi are as great as between the smallest and largest individuals of modern Fregata, which comprises 5 sexually dimorphic species (females larger). Thus, on size alone, Limnofregata would have to be divided into two species­level taxa, as the differences could not be due to differences between sexes, especially as the species of Limnofregata are unlikely to have been sexually dimorphic (see discussion below). The differences in bill proportions, with L. azygosternon having proportionately a much shorter bill, would also not be expected within a single species.

Limnofregata azygosternon Olson, 1977 Figs. 1���4 This species was described from a nearly complete skeleton with feather impressions (holotype USNM 22753) and two paratypes consisting of most of a right wing and shoul�� der girdle (UWY 6919) and the proximal end of an ulna (USNM 243766). Here we identify four additional specimens that can also be referred to the species Limnofregata azygosternon. Referred specimen 1: GMNH PV 167, postcranial skeleton with impressions of remiges and contour feathers (Fig. 1). Bone color brown, feathers black. Collected by Tom Lindgren. The specimen consists of all elements of the appendicular skeleton except the proximal portion of the right humerus, plus the complete pectoral girdle and pelvis. It is lacking the skull and mandible, a number of ribs, and the entire pre�� and postsacral vertebral column except for three thoracic and a caudal vertebra. Very distinct carbonized impressions of feathers can be identified as primaries, secondaries, and wing coverts. Locality: Smith Hollow Quarry, Lewis Ranch (Locality B of Grande and Buchheim, 1994), Lincoln County, Wyoming. Horizon: Beds about 4 m above the ��� 18 inch layer,��� Fossil Butte Member of the Green River Formation, late early Eocene. Measurements (mm): See Table 1. Referred specimen 2: FMNH PA 723, posterior portion of an associated skeleton consisting of the last 3 thoracic vertebrae, pelvis, caudal vertebrae and pygostyle, both hindlimbs complete with all toe bones, and assorted ribs (Fig. 2). Locality: Thomson Ranch (Locality H of Grande and Buchheim, 1994), ca. 14 km W of Kemmerer, Lincoln County, Wyoming. Horizon: F�� 2 facies, Fossil Butte Member of the Green River Formation, late early Eocene. Measurements (mm): See Table 1. Referred specimen 3: FMNH PA 720, complete left wing distal to the humerus (Fig. 3). Locality: Warfield Springs (NW 1 / 4, Sec. 5, T 19 N, R 117 W; locality K of Grande and Buchheim, 1994), ca. 14 km SW of Kemmerer, Lincoln County, Wyoming, on the SE shore of Eocene Fossil Lake. Horizon: F�� 2 facies equivalent, Fossil Butte Member of the Green River Formation, late early Eocene. Measurements (mm): See Table 1. Referred specimen 4: USNM 447002, left side of cranium with quadrate and associated posterior portion of mandible (Fig 4). The base of the bill and the occiput were preserved as a mold that has now been replaced with embedding compound. Locality: Ca. 12 km NE of Fontanelle Reservoir Dam on N shore at autumn water level, Sweetwater County, Wyoming. This locality is in beds of the Eocene Lake Gosiute, whereas all the other specimens of Limnofregata to date have come from deposits in Fossil Lake. Horizon: Laney Shale Member of the Green River Formation, lower middle Eocene. Measurements (mm): Quadrate: distance from posterior margin of mandibular articulation to tip of otic process, ca. 13.4. Description: Although USNM 447002 is very fragmentary, it is in places less crushed than other skulls of the genus. It shows a well��developed ectethmoid plate extending laterally from the mesethmoid, whereas the ectethmoid is much more reduced in Fregata. It emphasizes the large size of the orbit in Limnofregata, suggesting that the birds may have been partially nocturnal or crepuscular. In GMNH PV 167, the toes of the right foot appear to be in their naturally maximal spread position, and shows the much better development of the foot in Limnofregata compared with Fregata. Assuming that the foot was totipalmate, as in all modern Pelecaniformes, the area of the webbing was on the order of 20 cm 2. In the largest and best preserved of the primary feathers in GMNH PV 167, the tip is much less attenuated and sharply pointed than in Fregata. For FMNH PA 723, new information not preserved with the holotype concerns the tail. The number of free caudal vertebrae anterior to the pygostyle appears to be seven, as in Fregata. The pygostyle of Limnofregata was previously unknown, this element being entirely missing in the holotype of L. azygosternon. It is a broad plate as in Phaethon and Fregata, and completely unlike the pygostyle in the Sulidae, which is very thick and somewhat cylindrical proximally, tapering to a long, thin spine. In Limnofregata, the ventral margin of the pygostyle (Fig. 2) is rectilinear, the dorsal margin is curved, and the tip is broadly rounded., Published as part of Olson, Storrs L. & Matsuoka, Hiroshige, 2005, New specimens of the early Eocene frigatebird Limnofregata (Pelecaniformes: Fregatidae), with the description of a new species, pp. 1-15 in Zootaxa 1046 on pages 2-6, DOI: 10.5281/zenodo.169909, {"references":["Olson, S.

Limnofregata hasegawai, new species (Figs. 5���7) Holotype: GMNH PV 170, skull and mandible with quadrates, lacrimals, palatines, atlas, axis, and cervical vertebrae 3���7 (Fig. 5). Color brownish black. The skull is preserved in right dorso��lateral view with the mandible and right quadrate still in articulation. The left quadrate has been displaced and lies upside��down, with the mandibular articulation visible along the edge of the left orbit. The lacrimals are still nearly in articulation with the frontals, the right palatine is exposed but neither pterygoid is visible.

Etymology: To our esteemed colleague and friend Yoshikazu Hasegawa of the Gunma Museum of Natural History in recognition of his many contributions to vertebrate paleontology. Diagnosis: Much larger than L. azygosternon. Rostrum proportionately much longer, 1.6 times as long as the cranium, vs. 1.4 in L. azygosternon. Measurements (mm) of holotype: Measurements that are comparable to those published for Limnofregata azygosternon appear in Table 2.

We present a number of new fossil records of ‘‘waterbirds’’ (encompassing several of the traditional living orders of birds) from three important Miocene deposits in western Kenya. These sites surround Lake Victoria—the Ngorora Formation and sediments at Maboko and Rusinga Islands (Kula Formation)—are well-known hominoid localities, and have yielded a diverse assemblage of contemporary fossil mammals. Previously identified avians from this area include a marabou stork (Leptoptilos sp.), the fossil flamingo Leakeyornis aethiopicus, as well as a number of additional unidentified phoenicopterid (flamingo) remains. We add records of an anhinga (Anhinga cf. pannonica), two storks (Ciconia minor, C. cf. ciconia/nigra), a night heron (Nycticorax cf. nycticorax) and a threskyornithid (the group that includes the ibises and spoonbills) to the known diversity of Kenyan Miocene waterbirds. We also illustrate, for the first time, the holotype and paratype material of the Kenyan Miocene flamingo Leakeyornis aethiopicus. Comparisons with other known sites of this age across northern Africa, the Mediterranean and northern Pakistan suggest that Miocene waterbird faunas in this region were very similar in their compositions. While Anhinga pannonica, Ciconia minor, and Ciconia ciconia are documented from other Miocene sites across the region, the osteologically distinct fossil flamingo Leakeyornis appears to have been restricted to East Africa. All the avian groups recorded from these Kenyan Miocene sites represent extant genera, in contrast to the described fossil mammals. As has been widely reported from other African sites of this age, fossil birds thus represent a valid mechanism for building hypotheses about palaeoenvironments.

Four additional specimens from the Green River Formation of Wyoming are referred to the Eocene frigatebird Limnofregata azygosternon Olson, originally described from a nearly complete skeleton and two partial paratypes. Two skulls with mandibles and a partial postcranial skeleton are described as a new species, Limnofregata hasegawai, characterized by much larger size and a proportionately longer bill. One of the referred specimens of L. azygosternon is from Eocene Lake Gosiute, whereas all of the other specimens of Limnofregata are from Fossil Lake. The species of Limnofregata would have taken advantage of frequent periodic dieoffs of fish in the Green River lakes. Geological and climatic factors that may have influenced the paleoecology, distribution, and size variation in frigatebirds in the Cenozoic are reviewed.
