Habitat. Sispara ghat, Nilgiri hills, Southern India. 
This species is very near V. gigas, Bens. and still more closely allied 
to V. Peguensis, Theobald, being, however, a more depressed species 
than either, and more open. It is also less solid than the last named 
species. I have not met with the animal, which may possibly differ 
from those of other Vitrinx. 
If the animal resemble those of V. gigas and V. Peguensts, the oc- 
currence of this mollusk on the western flank of the Nilgiri Hills 
will be one of the most anomalous with which I am acquainted 
amongst the land-shells of India, since I know of no other instance of 
a Malayan type, unrepresented on the Himalayas, of which species 
occur on the hills of Southern India. A small auriform shell such as 
this may, however, have been easily overlooked, and the Himalayan 
Molluscan fauna is, probably, far from thoroughly known.* 
The animal of V. Peguensis has been partly described by Mr. Theo- 
bald who, however, has unfortunately not mentioned the form of the 
mantle, the presence or absence of lobes covering the shell, nor the 
existence of a caudal gland, unless by the expression “ caudali papilla 
nulla’ is intended to imply its absence ; more probably Mr. Theobald’s 
meaning is that the overhanging lobe, so conspicuous in some forms of 
Nanina is absent, the gland existing, as in Ariophanta &. 
This Vitrina is not the only south Nilgivi species. A larger mem- 
branaceous form also occurs, which requires comparison with Mr, 
Benson’s V. membranacea from Ceylon. 
8. Acuatina ANAMULLICA, n. s. 
Shell turrito-ovate, thin, finely striated, horny with high vitreous 
lustre. Spire turrited, sides convex, apex obtuse, suture impressed. 
* Mr. Theobald (J. A. S.°B. XXXIII. p. 244,) includes V. gigas in his list of 
Himalayan shells, but the species is found on the Khasi hills, the fauna of which 
differs widely from that of the Himalayas.
