MOLLUSCA OF INDIA. 71 
5, last well rounded below; aperture very ovate ; peristome thin 
and scarcely reflected. 
Size: major diam, 0-30, alt. axis 0-14 inch. 
x Tei . 35 mm. 
This species was sent me by Mr. Geoffrey Nevill, from the Indian 
Museum collection, Calcutta, where the type figured will be sent. 
It was, I believe, discovered by Colonel Mainwaring. Its generic 
position is very doubtful.

Locality of figured specimen. Jatinga valley, North Cachar Hills, 
and I have one other shell from Munipur. 
Sculpture, longitudinal fine ribbing, most marked on the apical 
whorls, crossed by fine, irregular, very oblique striz ; colour white. 
There is one of the four original specimens in Mr. W.T. Blanford’s 
collection, fixed upon a glass slide, with which I have compared 
the above, but it was too thin and delicate a shell to remove for 
figuring ; they agree perfectly. 
Size: major diam. 3:1, alt. axis 2°90 mm. 
Original description :—* Shell subperforate, turreted, white, 
horny, thin, translucent, marked with oblique sinuous subfiliform 
costulate striation, and below the centre of the whorl with very 
fine spiral lines, only visible under a powerful lens; spire conical, 
apex rather obtuse; suture deeply sunk. Whorls 6, very convex, 
keeled in the centre, the keel very fine, raised, thread-like, opaque 
and white; the last whorl bicarinate, the second raised spiral line 
being below the periphery ; flatly convex beneath, and marked by 
radiating striee and concentric impressed lines. Aperture oblique, 
tumidly and subangularly lunate, about equally broad and high; 
peristome thin; margins distinct ; columellar nearly vertical, very 
briefly reflexed at the penultimate whorl. 
“Diam. 13 mm. = 0-07 inch. 
«Height 2 \),, == 07038" ., 
“ Hab. Phoung-do, Arakan. 
« A minute species, remarkable for its keeled and convex whorls. 
Only four specimens were found.” 
It would be interesting to know the anatomy of this species and 
the relationship to its neighbours.
