Additions to the Collection of Oriental Snakes in the Indian Museum, 

 — By Nelson Annandale, B.A., Deputy Superintendent of the Indian 

 Museum. (With Plate IX) 



In 1891 my predecessor Mr. W. L. Sclater published his List of 

 the Snakes in the Indian Museum. Since that date a large number of 

 specimena have accumulated, the more important coming from the 

 North- West Frontier, Assam, Siam and Java. Among them are examples 

 of species of intrinsic or geographical interest or new to our collec- 

 tion. I propose to offer to the Society a series of short papers on 

 these specimens. For the sake of convenience, and in order not to in- 

 terrupt other work in progress, I will deal with the accumulation in sec- 

 tions of moderate bulk. This will make it possible to put on record 

 new specimens as they reach the Museum, and will enable such records 

 to be published within a reasonable time. The names of species new to 

 the collection since 1890 are distinguished by an asterisk. The iden- 

 tifications, except as regards the Afghan- Baluch species, are chiefly my 

 own, and I have made a careful re-examination of such specimens as 

 other offioiala of the Museum had determined.
