Shell ovate, with moderately elevated spire, composed of six or seven convex 
whorls, which are separated by simply impressed sutures; last volution very globose 
and evenly rounded at the periphery; aperture ovate, inner lip thin, columella at its 
termination distinctly but narrowly excavated. The strong globosity of the whorls 
well characterizes this species, which was first described by Sowerby from the Black- 
down Greensand beds as a Turbo. 
Locality —Comarapolliam, in light colored sandstone ; rare. 
Formation. — Arrialoor group.

Eusp. testa sub-globosa, spira brevi, acuminata ; anfractibus planiusculis, postice 
ad suturas truncatis atque applanatis ; ultimo valde inflato, ad medium latissimo, 
convexo; superficie striis imcrementi minutis atque alteris spiralibus numerosis 
puncturatis notata; apertura dilatata, postice angustata, antice lata ac rotundata, 
labio tenui, columelia ad terminationem furcata. 
Spiral angle 98°; sutural angle 6°.

This species has somewhat the form of a small and depressed specimen of 
Amp. bulbiformis, but it is readily distinguished from it by the want of any strong 
callosity on the inner lip, and by a much finer and closer punctuation of its surface. 
The whorls are posteriorly flattened near the suture, and marked with 3-4 very 
fine spiral striz. The last whorl is broadest about the middle and convex, the 
inner lip anteriorly, at the termination of the columella, somewhat flattened and 
distinctly grooved, but not fissured. 
The species resembles Forbes’ Natiea obliquestriata, and from the author's 
description one would certainly suppose them to be the same, though this is not the 
case (vide postea). 
Locality.—Kolakonuttom, in bluish sandstone; pretty common. 
Formation.—Ootatoor — and Valudayur — groups.
