REMARKS. — Mastonia funebris is characterized by the colour pattern of a white first spiral cord on a brown background (“ le rang antérieur est d’un noir plus ou moins foncé, le postérieur d’un blanc de porcelaine ”). One specimen of the type series (Fig. 47) does not fit this description as it has a brown background again, but with a slightly darker first spiral cord. Additionally, its protoconch bears a single spiral keel on its lower whorls, whereas M. funebris bears two. Therefore, to stabilize the nomenclature, we designate here the lectotype of M. funebris (Fig. 46)., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 72, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["JOUSSEAUME F.

REMARKS. — The type series contains several lots and more than one species. Lot MNHN-IM-2000-482 contained a Cerithiopsid (Fig. 60U). The lot MNHN-IM-2000-480 contains a single white specimen (Fig. 60 R-S), with a more elongated shape, and thicker and more strongly tubercled spiral cords on the base. Similar white specimens were present in MNHN-IM-IM-2000-481 (2 specimens, but one is so worn to hamper any identification). MNHN-IM-2000-482 contained a white specimen with a weaker first spiral cord (Fig. 60T); its general appearance may reflect a teratological specimen as well as a distinct species, but the shell condition is inadequate for a precise identification. Last,the type series contained also two fresh pink to violet specimens (“ rosacea-rubida ” as in Jousseaume’s original description). One of them shares the same approximate number of whorls and size as in the original description and is here designated as lectotype to stabilize nomenclature (Fig. 60 A-F)., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 90, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["JOUSSEAUME F.

ORIGINAL DESCRIPTION. — Testa solida, ovato-conica, apice acuminata, albo et nigro zonata; anfr. circiter 12 primi albi, alteri seriebus tuberculorum tribus, mediana saepe minor, series antica alba, alterae castoneo-nigrae, granulae spiraliter et longitudinaliter funiculo junctas, ultimus quique seriebus granularum rugatus, series postice 2 fulvo nigra, pars antica alba, reticulata; apertura pyriformis, lateraliter fissa; canalis brevis recurvus. Long. 3 mm3; diam. 1 mm2. [Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Solid shell, ovate-conical, acute apex, banded in white and brown; about 12 whorls, the first whorls are white, the other whorls with three series of tubercles, often the median series is smaller, the anterior series is white, the others are brownish, granules are spirally and longitudinally jointed to a small spiral cord, last whorl with five granular spiral cords, two posterior cords dark brown, anterior ones are white, reticulated; pyriform aperture, laterally fissured; short and curved siphon.

First and third cords with tubercles at the intersection with rather orthocline axial ribs. Second cord initially as a fine thread, but later developing thin tubercles. Spiral microsculpture of fine threads. Posterior sinus shallow. Base with two additional weakly tubercled spiral cords, the second smaller. Protoconch damaged in the lectotype. First two teleoconch whorls white, other teleoconch whorls brown with the third spiral cord white. Tip of the siphonal canal and protoconch white. REMARKS. — The type series contained a very worn specimen (Fig. 63 I-M) which likely belongs to a different species due to the more ovoid shape, the colour pattern on the last whorl (with the first spiral cord white rather than pearly on brown background), the tubercles on this last whorl more elongated, and the lack of an intermediate second spiral cord. Therefore, se designated a lectotype of O. senilis to stabilize the nomenclature., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 94, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["JOUSSEAUME F.

[Latin diagnosis followed by a discussion in Italian] TRANSLATION OF THE LATIN TEXT. — Elongated-fusiform shell, acute, bright, white; from 12 to 13 flat whorls, narrow, very slowly growing, adorned by a double series of granules; last whorl is short and slightly angled at the periphery, costulate at the base; oval and narrow aperture, oblique, ending with a very short siphon. — Length 4-5 mm; diameter 1 1/2-1 1/3 DIAGNOSIS. — MNHN syntype 4.7 mm high, but missing the apex. Shell cyrtoconoid with c. 9 (MNHN syntype) to c. 13 (Savigny’s figure) flat whorls, with two main spiral cords with tubercles at the intersection with slightly prosocline axial ribs and a third cord developing in between in the lower half of the shell, initially as a fine smooth cord and with well-developed tubercles only on the last whorl. Peristome missing in the MNHN syntype. Base with three, apparently tubercled, additional cords. MSNG specimen with multispiral protoconch. MNHN syntype generally whitishgreyish, but colour unreliable due to the state of the specimen; still an orange stripe is visible between the main cords, suggesting a dichromatic colour pattern. REMARKS. — Issel’s original description is based on the specimen illustrated by Savigny (1817) (see also Bouchet & Danrigal (1982)). The resolution of this figure is very low and the diagnostic characters are not present in sufficient detail. The MNHN syntype is in terrible condition, lacking the apex, part of the last whorl, and being very worn. Still, it matches Savigny’s illustration well. The MSNG syntype is in better condition. Its label clearly states that the specimen comes from raised beaches and is thus a fossil specimen., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 59, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["ISSEL A. 1869. - Malacologia del Mar Rosso.

The MNHN contains a lot with three specimens, all adults. Montrouzier wrote that he analysed indeed three specimens, but one clearly juvenile that was illustrated in his figure 4 on plate 9. Because of the explicit statement of Montrouzier and the fact that no juveniles are present in the lot in the MNHN, we do not consider these specimens belonging to the type series, although apparently belonging to Montrouzier’s collection., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 103, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["SOUVERBIE M. & MONTROUZIER R.

[Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Elongated and turreted shell, completely dark brown, acute apex; thirteen whorls, with three equal and simple spiral rows, the interspaces bear very small cavities, short last whorl, angulated at the periphery, flattened at the base; small squarish aperture, ending with a short siphon.

First and third cords smooth, the second developing flat tubercles. Microsculpture of numerous fine spiral threads in spiral interspaces. Peristome with an additional cord below the second cord. Posterior sinus shallow. Base with two additional smooth spiral cords. Protoconch missing in the syntypes. Teleoconch whorls with brown flammulae on a white background. The first thread is darker. Protoconch brown. REMARKS. — The specimens marked as syntypes belong to different species. Lot MNHN-IM-2000-1576 (Fig. 11 B-I) contains the specimen best matching the original description and figure but lacks the uniform brown colour cited in the original description (“ omnino castaneofusca ”). Lot MNHN-IM-2000-1577 contains three specimens belonging to two species different from T. triliratus: two are fragments that have the second spiral cord just as a fine thread (Fig. 11K, L), the third is probably a Viriolopsis B. A. Marshall, 1983 (Fig. 11M). Lot MNHN-IM-2000-1578 contains a damaged specimen which is probably T. intergranosa Hervier, 1898 (Fig. 11N). This situation would require the designation of a lectotype. However, we still do not know the intraspecific variability of this species-group and thus if the syntype MNHN-IM-2000-1576 can really belong to T. triliratus as described. Therefore, we prefer to avoid any designation until the group is better understood., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 27, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["DESHAYES G.

TRANSLATION OF THE LATIN TEXT. — Sinistral shell, elongated, narrow, acute apex, white-yellowish, at the base and at the apex light brown. Whorls about 15: first whorls brownish, narrow, with two unequal and equidistant spiral cords, adorned by transparent granules. The first cord is smaller, coloured in brown-yellow in the last whorl; the second cord is larger, characterised by a discontinuous yellow cord between the granules. Last whorl is quite long, depressed at the base, adorned by four granulated spiral cords; in the dorsal part (at about half of the whorl), it is characterised by a very long tubular siphon near the suture, adorned by a cancellated structure with four granulated spiral cords and striae, extending to the aperture. Siphon is elongated, strongly oblique, curved, completely closed. The aperture is small, rounded, tubular, slightly protruding, peristome continuous. Length 6-7 mm; maximum diameter 1.25-1.50 mm. Locality: Lifou Island. I saw 10 specimens collected by R. P. Goubin. DIAGNOSIS. — Shell very elongated with flat sides. Lectotype 5.9 mm high. Teleoconch of c. 13 whorls. Two spiral cords present with the lower being more prominent. Cords with strong tubercles at the intersections with slightly prosocline axial ribs. A very fine thread present below the first cord. Peristome with an additional cord below the first cord. Posterior sinus well developed and protruding into a canal. Base with two additional tubercled cords. Teleoconch white with brown interspaces between the tubercles on the second cord. First cord becoming light brown on the lower whorls. A brown blotch present on the base. REMARKS. — The original lot contained a specimen (Fig. 21 B-F, H, I) and a fragment (Fig. 21 J-N), the latter not matching the description of lifuana but possibly of Contraforis insulana Laseron, 1958 or Triphora (Iniforis) bellula Kosuge, 1961. Triforis lifuana is characterized by the dark interspaces between tubercles on the last spiral cord and by having more numerous and less prominent such tubercles. Therefore, we designate the lectotype to stabilize the nomenclature., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on pages 40-43, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["HERVIER J. 1898. - Diagnoses d'especes nouvelles de Triforis, provenant de l'archipel de la Nouvelle-Caledonie (suite).

[Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Ovate shell, rather solid, broad, reduced apex; 13 whorls, adorned by three series of tubercles (the median series is smaller, other series are equal), separated by a barely distinct suture; the last whorl is coloured in yellow at the base and adorned by five tubercled spiral cords; pyriform aperture, laterally fissured; short siphon. — Length 4, diameter 1.5 mm. DIAGNOSIS. — Shell cyrtoconoid. Lectotype 3.4 mm high.Teleoconch of 7.5 whorls. Three spiral cords present, the second appearing on the sixth whorl. First and third cords with tubercles at the intersection with rather prosocline axial ribs. Second cord initially as a fine thread, but later developing thin tubercles. Spiral microsculpture of barely visible fine threads. Peristome with additional cords below the second and third spiral cord. Posterior sinus relatively deep. Base with three additional spiral cords of which the first developing tubercles, the other two smooth. Protoconch incomplete in the syntype, but clearly multispiral with one spiral keel and equally strong axial riblets.Teleoconch and protoconch brown, with the first teleoconch whorl and the base lighter. REMARKS. — Lot MNHN-IM-2000-1614 contained six specimens belonging to two, if not more, species. One morphotype (Fig. 57 B-K) is more slender, uniformly brown except the yellowish base, bears two main tubercled spiral cords with a third developing as a thin thread until the last whorl where it is fully developed. The second morphotype (Fig. 57I) is broader and with a marbled colour pattern with irregularly positioned lighter tubercles and darker interspaces. Due to Jousseaume’s reference to the yellow base (“ ultimo ad basin luteo - tincto ”), we here consider that the first morphotype represents M. obesula and here designate its lectotype to stabilize the nomenclature., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 86, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["JOUSSEAUME F.

Triphora (Mastonia) lamyi Selli, 1974 (Fig. 72) Triphora (Mastonia) lamyi Selli, 1974: 332, plate XIX, figs 10-12. TYPE MATERIAL. — Syntypes. Egypt • MNHN-IM-2000-486; 2 specimens; Gulf of Suez. REMARKS. — Selli (1974) cited this new name in his treatment of Mastonia maenades Jousseaume, 1898. He recognized that his specimens could not be separated from those illustrated by Lamy (1938) with this name, highlighting that Jousseaume did not illustrate them and that Lamy himself had doubts on his own identifications. He then stated that “if ” the holotype was lost or did not correspond with Lamy’s figure, then he would have named his specimens T. (Mastonia) lamyi. Consequently, at the time of his publication, Selli was not yet using this name as valid for a taxon and this name is thus unavailable according to art. 11.5 of ICZN (1999). In any case, a comparison of the specimens of T. lamyi with those of M. moenades did not enable us to recognize any significant difference., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 104, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["SELLI R. 1974. - Molluschi quaternari di Massaua e di Gibuti., Missione geologica dell'Azienda Generale Italiana Petroli (A.

ORIGINAL DESCRIPTION. — Testa parva, solida, ovata, ventricosa, apice attenuata, acuminata, alba maculis ferrugineis aut fulvo-nigris irregulariter tincta; anfr. circiter 12 seriebus tuberculorum duobus ornati, intertitiones cancellatae, sutura profunda, distinctissima separati, ultimus antice attenuatus costis, quatuor moniliformibus rugatus; apertura pyriformis, lateraliter fissa, canalis brevis. Long. 2mm 2; diam. 1mm. [Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Small shell, solid, ovate, broad, slender apex, acute, irregularly coloured with white, rustcoloured or dark brown spots; about 12 whorls adorned by two series of tubercles, with cancellate interspaces, separated by a deep and very distinct suture, anteriorly reduced last whorl with four tubercled spiral cords; pyriform aperture, laterally fissured, short siphon. Length 2.2 mm; diameter 1 mm. DIAGNOSIS. — Shell cyrtoconoid. Lectotype 2.4 mm high.Teleoconch of 6.5 whorls. Three spiral cords present, the second appearing on the sixth whorl. First and third cords with tubercles at the intersection with rather prosocline axial ribs. Second cord initially as a fine thread, but later developing tubercles. Base with three additional tubercled spiral cords. Second spiral cord on the base smaller. Multispiral protoconch of 5 whorls with two spiral keels and equally strong axial riblets. Nucleus eroded in the lectotype but apparently with a reticulated sculpture. First teleoconch whorl white, the following ones white with orange-brown blotches. Base brown. Protoconch most likely light brown but faded in the lectotype. REMARKS. — The type series contained two lots and two species. Obesula pantherina is characterized by its acuminate shape (“ acuminata ”), with four distinct tubercled spiral cords on the last whorl (“ quatuor moniliformibus rugatus ”). However, lot MNHN-IM-2000-1597 contained three shells of which only one in good condition (Fig. 58 I-L), characterized by a more oval shape and only three distinct spiral cords on the last whorl. Additionally, this specimen has a spiral microsculpture and a colour pattern that readily distinguishes it from O. pantherina. To stabilize nomenclature, we here designate the lectotype of O. pantherina (Fig. 58 A-H)., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on pages 86-90, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["JOUSSEAUME F.

Triphoris ornatus Deshayes, 1832 (Fig. 8) Triphoris ornatus Deshayes, 1832: 1053, not illustrated. TYPE LOCALITY. — Unknown. TYPE MATERIAL. — Not found (see Remarks). ADDITIONAL MATERIAL. — Reunion Island • MNHN-IM-2000-483; 1 specimen; apparently from the Red Sea. No clear locality indicated • MNHN-IM-2000-503; 4 specimens. ORIGINAL DESCRIPTION. — Tr. test â sinistrors â, elongato-turrit â, apice acut â, basi angustâ, in medio laeviter inflatâ; anfractibus numerosis, planis, b iseriatim granulosis; granulis superioribus rufis, alteris albidis; aperturâ rotundatâ, submarginatâ; siphon posticali brevi, simplici. [Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Sinistrorse triphorid shell, elongated and turreted, with sharp apex, narrow base, in the middle slightly inflated; numerous whorls, flat, with two tubercled spiral cords; upper tubercles red, the others white; circular aperture, with lip; posterior siphonal canal short, simple. REMARKS. — The MNHN hosts two lots that have been assigned to this taxon. Apart from some very ruined shells in lot MNHN-IM-2000-503 (Fig. 8 R-T), whose conditions prevent any comparison, one specimen in this lot (Fig. 8 H-P, V) and the specimen in lot MNHN-IM-2000-483 (Fig. 8 A-G, Q) share the same colour pattern of a brown or orange second spiral cord on white background. Deshayes indeed stated that the “upper” spiral cord is reddish and the rest white (“ granulis superioribus rufis, alteris albidis ”). The meaning of “upper” is ambiguous. We noticed also in some descriptions by Jousseaume that “upper” was occasionally used for the second cord, and we wonder if this is not a relic of the early days when shells were depicted with the spire downwards (and thus the second spiral cord up). That is, if Deshayes actually meant by “upper” closer to the aperture, both specimens may fit the original description. Still, the two specimens likely belong to two different species, the original locality is not stated, and the original description may fit multiple known species. Therefore, the correct identity of Triphoris ornatus is very hard to define, unless some unambiguous type material shows up., Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on page 24, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/7569742, {"references":["DESHAYES G.
