Inella rossiteri Jousseaume, 1884 (Fig. 63) Inella rossiteri Jousseaume, 1884: 249, pl. 4, fig. 9. TYPE LOCALITY. — New Caledonia. TYPE MATERIAL. — Lectotype. New Caledonia • MNHN-IM-2000-29272; here designated. Paralectotypes. New Caledonia • MNHN-IM-2000-1246; 1 specimen; from type locality • Triphoridae indet.: MNHN-IM-2000-1313; 1 specimen. ORIGINAL DESCRIPTION. — Testa cylindrico-conica, ventrosula, rufolutescente; anfractibus 14 planis, sutura profunda, canaliculata, discretis; tuberculis albescentibus, contiguis et oppositis, in seriebus quatuor dispositis, muricatis; ultimo ad basin depresso, carinis octonis, moniliferis ornato; apertura subrotundata, lateraliter fissa, canali brevi, aperto, munita. — Long. 5-6, lat. 1,5-1,7 millim. [Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Cylindrical-conical shell, quite swollen, red-yellowish; 14 flattened whorls, separated by a deep canaliculated suture; tubercles are whitish, contiguous and opposing, arranged in four series, pointed; the last whorl is depressed at the base, adorned by eight granular spiral cords; roundish aperture, laterally fissured, with a short and open siphon. — Length 5-6, diameter 1.5-1.7 mm. DIAGNOSIS. — Shell cyrtoconoid. Lectotype 5.2 mm high, paralectotype 5.9 mm high. Teleoconch of 8 whorls. Four spiral cords present, the third appearing on the third whorl, while the second on the sixth. First and fourth cords with tubercles at the intersection with rather prosocline axial ribs. Second and third cord initially with thin tubercles, becoming larger towards the last whorl. A smooth thread present suprasuturally. Peristome without additional spiral cords. Posterior sinus shallow. Base with four additional rather smooth spiral cords. Multispiral protoconch of c. 4 whorls with one spiral keel and axial riblets. First four teleoconch whorls light brown, then teleoconch progressively lighter. Protoconch light brown. REMARKS. — The type series contained two lots. Lot MNHN-IM-2000-1313 contained a single triphorid fragment (Fig. 62R) which can be easily recognized not to belong to Inella rossiteri due to the presence of only three tubercled spiral cords instead of four, a very specific character of I. rossiteri, rarely found among the Triphoridae.
