loc. cit.) 
We re-produce with slight alterations Forbes’ figure of the only specimen that 
has yet been obtained. It is in many respects very incomplete, and the generic 
determination remains, therefore, doubtful, because the species may be proved to be 
a Chlorostoma or some other genus allied in form. The columella is solid, twisted, 
and terminates anteriorly with a strong obtuse point. The whorls are ornamented 
with transverse ribs, of which about three in each circuit are stronger than others ; 
they also produce deeper sulcations on the cast. The basis of the last whorl is 
rather angular, and when the shell was preserved it was no doubt still more so. 
The number of spiral strize in one whorl varies from 7 to 10. 
Locality.—Pondicherry, in light coloured sandstone. 
Formation.—Arrialoor group.

The single specimen in our collection is rather imperfect ; but the presence of 
transverse ribbings, some of which are stronger than others, and the solid columella 
being anteriorly somewhat flattened and grooved make the generic determination 
of the species rather probable. The whorls are convex, and each is ornamented with 
three subtuberculated strive, two of which are placed near the middle and one near 
the anterior margin of the suture. Imperfect specimens of this species are dis- 
tinguished from Uvanilla Rajah by the want of a twisted columella. 
Locality —Comarapolliam, in whitish sandstone; very rare. 
Formation.—Arrialoor group. :
