 ON A COLLECTION OF SNAKES FROM DEHLI.

During his stay in Laboean (Dehli, East-Sumatra) Dr. 

 B. Hagen, to whom the Leyden Museum is indebted for 

 large series of mammals, birds and insects, also collected 

 a large number of snakes , the greater part of which were 

 sent to our Museum. Dr. Hagen took a lively interest in 

 snakes, and being convinced of the benefit a colonist 

 might derive from the knowledge of the venomous snakes , 

 living in his neighbourhood, he gave some years ago 

 a description of those dangerous animals and their ha- 

 bits in the »Dehli-Courant". As some of his statements 

 were unknown to me and may perhaps be generally un- 

 known , I shall take the liberty to mention these facts in 

 this note, a newspaper as the Dehli-Courant being not 

 likely to be consulted in matters of herpetology. 



Afterwards the Leyden Museum was presented with a 

 collection of snakes from Dehli by Mr. J. Chr. Prakke, 

 who collected them in the neighbourhood of his planta- 

 tion at Langkat. 



The snakes of Dehli are now represented in the Leyden 

 Museum by 43 species , and though only one species and 

 one variety have till now been left undescribed, I thought 

 it worth while to give a full list of the species represented 

 in our Museum , as the occurrence of some of them as 

 Psamnodynastes pictus Gthr. and Dryophis fasciolatus Fi-
