Notes on the distribution of some oftlie land and freshwater shells of 

 India : Part I. — By W. Theobald, June. 



BlEHAH AND THE TENASSEEIM PeOVINCES. 



In the present paper it is my intention to give a sketch of the 

 distribution of the land and fluviatile shells of certain portions of 

 India, as far as they have been observed, in the hope that my notes 

 may prove a not uninteresting addition to our previous knowledge 

 of the subject, and shew by the great addition now made to the list 

 of known species, how much yet remains to be done in this depart- 

 ment of Natural History. 



The names used are with scarcely an exception those furnished by 

 Mr. Benson, who has described many of the new species in the 

 Annals and Magazine of Natural History for last year, though 

 many still possess merely MSS. names, which, together with the 

 new species described from specimens furnished by me, I have indi- 

 cated in the following list, by asterisks (*). 



On my first communicating with Mr. Benson, he informed me 

 that but twenty-three species of land shells were authentically 

 known from the Tenasserim Provinces. Of these, four species, which 

 escaped my notice, may here be mentioned to complete the list up 

 to the present time, viz. 



Yitrina Birmanica, Philippi. 

 Bulimus moniliferus, Gould. 

 Cyclophorus perdix, Sav. 

 Leptopoma Birmanum, Pfr.
