Djibouti • MNHN-IM-2000-506; 1 specimen • Mastonia cf. servaini Jousseaume, 1884 , MNHN-IM-2000-29268; 1 specimen . ORIGINAL DESCRIPTION. — Testa solida, obesa, ovato elongata , apice acuminata, alba et fulvo flavica spiraliter zonata, granulis biseriatim dispositis cincta, intertitiones funiculo parvo et striis tenuissimis spiraliter ornata; anfr. 15 16 sutura parum distincta separati, primi 2 corneofulvi, sequentes 2 albi, postea 4-5 seriebus granulurum duaebus (antica alba, postica fulvo-nigra), cincti, alteri serie antica alba, postica flavida ornati, ultimus contractus, costis quinis granulosis inaequalibus rugatus, intergranulas linea interrupta nigricante spiraliter picta; apertura subquadrata rotundata, labrum album, saepe fulvo maculatum, ad suturam profunda fissum, canalis albus recurvus. Long. 8mm ; lat. 2mm 5. [Latin diagnosis followed by a discussion in French] TRANSLATION OF THE LATIN TEXT. — Solid shell, broad, ovate-elongated, slender apex, spirally banded in white and brown-yellowish, with two series of granules, spirally adorned by a small cord and very fine growing lines; from 15 to 16 whorls separated by a slightly distinct suture, first two whorls are corneous-brown, subsequent two whorls are white, subsequent 4-5 whorls with two series of granules (anterior series is white, subsequent series is dark brown), the other series of whorls are adorned by an anterior white cord and a posterior brown cord, restricted last whorl, with five granular unequal spiral cords, spirally coloured with a interrupted brownish line between granules; squarish and rounded aperture, white lip, often spotted with yellow, fissured near the deep suture, white and curved siphon. Length 8 mm ; diameter 2.5 mm . DIAGNOSIS. — Shell rather conical with flat sides. Lectotype and paralectotype 7.0 mm high.Teleoconch of c. 12 whorls. Three spiral cords present, the second appearing on the ninth whorl. First and third cords with tubercles at the intersection with prosocline axial ribs. Second cord initially as a fine thread, but later developing thin tubercles. Spiral microsculpture of weakly granulate fine threads. Peristome without additional spiral cords. Posterior sinus relatively deep. Base with two additional tubercled spiral cords. Second spiral cord on the base thinner.Teleoconch white with the first spiral cord orange; on the lower whorls, yellow to brown only in the interspaces between the tubercles on the first spiral cord. Brown interspaces between tubercles on all spiral cords on the last whorl. REMARK. — The lot contained a specimen that, although subadult and worn, clearly does not belong to M. peanites ( Fig. 59J ) due to its colour pattern with brown spots between white tubercles on the second cord. This pattern resembles closely Mastonia servaini Jousseaume, 1884 , although we remark that multiple species share this colour character.
