320 Notes on some Indian Freshwater Shells. [No. 4. 



Streptaxis, Gray. 



31.* 8. Theohaldi, B. — Nanclai. Rare ; amongst limestone rocks. 

 Yitrina, Draparnattd. 



32. V. Gigas, B. — Near Teria ghat, but at some elevation, and 

 also at Cherrapunji, length of a large shell 1.45. 



33.* V. Scutella, B. — Teria ghat, rare. 



34.* V. Salius, B. — Teria ghat, rare. The animal is a livid 

 plumbeous colour, addicted to limestone rock in the sinous cavities 

 of which it is chiefly to be found. It is very active and when 

 touched, leaps several inches by rapidly twisting and whirling its 

 tail in a very vermiform manner, indeed till this habit is known, it 

 is not easy to secure in the rough places it mostly frequents. 

 jBulimus, Scopoli. 



35.* B. JPolypleuris, B. — A pretty little scalariform species, of 

 which a single specimen only was found at Teria ghat. 



36. P. Sylheticus, B. — Not met with by me but included in 

 Mr. Benson's list of Sylhet shells. It is found in the orange tree 

 plantations at Lacat. 



AcJmtina, Lamarck. 



37.* A. JPyramis, B.— Teria ghat. Abundant under leaves and 

 rubbish. 



38. A. Crassilabris, B. — Teria ghat, rare. 



39. A. Cassiaca, B. — Not found by me but included in Mr. 

 Benson's list. 



40. A. sp. In too poor a state for description. 



41. A. sp. Ditto ditto. 



Pupa, Lamarck. 

 42.* P. Vara, B. — Nanclai. Very rare. 



43. P. Flicidens, B. — Cherra. — Yery common on limestone rocks 

 This is a Western Himalayan species. 



Clausilia, Draparistatjd. 



44. C. Loxostoma, B. — Teria ghat. Very common, attached to 

 rocks or stones. This shell differs much in appearance, being some- 

 times found entire and with clean epidermis, in others covered with 

 green matter and decollated. This difference is the result of situ- 

 ation, those specimens taken from rotten trees and beneath the 

 loose bark being perfect, whilst those attached in esposed situations
