essential particular from the Bengal variety. The species has not 

 before, so far as I am aware, been found in Southern India. N. Ship- 

 layi, Pfr. inhabits the eastern base of both the Anamullays and the 

 Nilgiris ; on the latter hills I have found it at the foot of the Coonoor 

 ghat. The animal is a Nanina, closely resembling N. indica, Pfr. and 

 N. acuducta, Bens., having a large mucus pore at the caudal extremity 

 of the foot without an overhanging lobe, or with but a very rudimen- 

 tary one. The mantle lobes are small, and the animal in all respects 

 closely resembles that of the sub-genus Ariophanta. A solitary speci- 

 men of N. indica from the Anamullays is very solid and rather strong- 

 ly marked, the sculpture being less regular than in the common 

 Nilgiri form, and scarcely granulate, the last peculiarity being perhaps 

 due to weathering, as the specimen is decorticate and somewhat 

 bleached. It is a dwarf form, less depressed than the type, and mea- 

 sures 17 and 15 millem. in its two diameters, and 10 in height. The 

 shells found on the Nilgiris vary considerably. 



N. Basilens, Bens. (H. Titanica, Pfr.^), I learn from Captain Bed- 

 dome, is far from scarce in the teak forests of the Anamullays, a tract 

 2,000 to 3,000 ft. above the sea, where N. ampulla, Bens, also occurs. 

 The range of the latter shell extends a considerable distance to the 

 north in the Wynand district, where it was found by Dr. Jerdon, if 

 not to the base of the Coorg hills, while N. Basilens does not appear 

 to be found north of the remarkable gap in the Western Ghats at 

 Paulghat cherry, which, traversing the very highest portion of the 

 whole chain, divides the Nilgiris from the Anamullies, and through 

 which the railway from Madras to Beypoor passes. Both N. ampulla 

 and N. Basilens have only been found west of the Hills. 



I have not had an opportunity of comparing the shell referred 

 doubtfully to Mr. Benson's recently published N. Travancorica with 

 the full description, and the identification is therefore unsatisfactory. 

 The shell referred to N. auris, Pfr. is identical with a species found at 

 Neddiwuttom on the Nilgiris, and corresponding closely with Reeve's 

 figure of that N. auris in Conchologica Iconica. 



The little shell which I have called Bulimus Nilagaricus, I was at 

 first disposed to consider a distinct species. It is only 14 millem. in 

 length, and base by 6 in diameter. But some specimens from the 

 Nilgiris are no larger, and there are graduations in size from these to
