Epitonium alabiforme
Kilburn, 1985
Description:
Dimensions range from 3.7 mm - 4.2 mm high.
Width to height ratio: 00:1 ~ 00:1
Shell: narrowly pyramidal; minute. Exterior colour white. About 5 whorls, strongly convex; protoconch damaged in holotype; teleoconch strongly convex. Suture very deep but simple. Umbilicate: narrow, deep. Approximately 13 - 16 costae on the body whorl. Costae are prosocline, low, rather narrow, varying in width. Costae not reflexed; discontinuous. Intercostal spaces smooth. Aperture oblong-ovate, lip with a wide, slightly rounded, thick costae behind; peristome moderately thick, except for labium, which is not reflexed.
Kilburn [1985] notes that the conspicuously swollen posterior part of each whorl and the deep suture distinguish E. alabiforme from E.(P .) perlucidum and E.(P .) lachrymulum (Jousseaume, 1912) from the Red Sea.
