Vexillum crocatum (Lamarck 1811)

Vexillum crocatum, common name : the saffron mitre, is a species of small sea snail, marine gastropod mollusk in the family Costellariidae, the ribbed miters.^[1]

Description

The shell size varies between 17 mm and 36 mm

(Described as Mitra concinna) The ovate shell is contracted at the base. The spire is turreted. The whorls are angulated at the upper part and longitudinally ribbed. The ribs are granosely pointed upon the angle, transversely crossed with small obtuse ridges. The ridges are bright yellow, the interstices very dark chesnut. The columella is four-plaited. ^[2]

(Original description as Mitra assimilis) The oblong shell is subfusiform, turreted, solid and shining. It is whitish, with closely set transverse deep-brown slightly raised lines. The spire is moderately elevated and acute . The shell contains 8-9 whorls, plano-convex, shouldered above, longitudinally ribbed. The ribs are closely set, angular, slightly nodulous, 16 to 18 in number. The body whorl is convexly rounded, contracted and granulated at the base. The aperture is narrow, bluish white and lyrate within. The outer lip is rather sharp and crenulate. The columella shows four folds. ^[3]

Distribution

This species occurs in the Red Sea, in the Indian Ocean off Chagos and the Mascarene Basin, and in the Indo-West Pacific.
