the typical shells. The solitary specimen of B. pliy sails has only 

 traces of spiral sculpture, but it appears to agree in every other respect 

 with Mr. Benson's description. 



A dwarf form of GyclopJwrus Jerdoni, only 29 millem. in diameter 

 and 19 high, and 2 species of Pterocyclos, one of them unquestionably 

 identical with Pt. nanus, Bens., are also comprised in Captain Bed- 

 dome's collections. The second species of Pterocyclos of which a 

 single weathered specimen was found, shews no essential distinction 

 from the Bengal Pt. mpestvis, Bens., but it appears improbable that 

 that form should really exist so far to the south. 



Cyclopliorus deplanatus, Pfr. some decorticated specimens of which 

 were amongst the Anamullay shells, occurs abundantly on Sispara 

 ghat, at the western extremity of the Nilgiri plateau. A small shell 

 in Captain Beddome's collections, with more colouring than G. ravi- 

 dusj Bens., and ornamented with zigzag transverse stripes, may possi- 

 bly be a young specimen of that species, but its thin and continuous 

 peristome recalls that of some forms of Aulojwma, and the possibility 

 of its belonging to that genus is strengthened by the deficiency of the 

 epidermis close to the peristome. As the Anamullays have already 

 furnished a Cataulus, the occurrence of a species of Aulopoma is by no 

 means improbable. 



The Paludomus is perhaps a variety of the species common near 

 Bombay. The little Neritina Perrotettiana was previously unknown 

 except in the Pykara river on the Nilgiris. 



We have evidently, as yet, only an instalment of the molluscan 

 fauna of the Anamullays. None of the shells above specified are from 

 the higher ranges. So far as they have been collected, there is, as 

 might have been anticipated, a general identity with Nilgiri shells, 

 but at the same time a somewhat closer approximation to the Cinga- 

 lese fauna. 



P. S. — The above paper was written six months ago, and would 

 have been sent for publication in the Society's Journal at once, but 

 that I hoped to be able to procure drawings of the shells for the pur- 

 pose of illustrating it. In this, I have again been disappointed, and I 

 am compelled to forward the descriptions of the shells by themselves. 



In the meantime, however, I have received from Captain Beddome 

 several additional shells from the Anamullay hills collected by him
