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 Vitrimu. 



If the animal resemble those of V. gigas and V. Peguensis, 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. Pegucnsis 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 Ariojphanta &c. 



This Vitrina is not the only south Nilgiri species. A larger mem- 

 branaceous form also occurs, which requires comparison with Mr. 

 Benson's V. membranacea from Ceylon. 



8. Achatina 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.
