toxicology. These specimens, nearly all venomous, I could distinguish 

 because they had been preserved in spirit, whereas the rest of the 

 specimens are in formalin. Dr. Vincent Richards' specimens are not 

 local ones, but were certainly collected in the Bengal Plains where 

 he spent all his service. 



The specimens collected by me locally in and about Darjeeling are 

 from altitudes well between 0,000 and 7,500 feet. 



From Pashok I obtained 31 species, and from Tindharia 25. 

 From Kurseong only 6 out of 242 specimens. From Darjeeling 

 I o-ot only 9. In the Darjeeling Museum there are 30 species and 

 in St. Joseph's College 37, at least 9 of which are certainly not 

 local, viz., Eryx conicus, Simotes arnensis, Dipsadomorplms gohool, 

 andD. forstein^Bungariis cceruleus, B. fasciatus, and B. imlli, EcUs 

 carinatus, and Vipera Tusselli. 



Of the 48 species with which this paper deals 42 were obtained 

 by or for me, the remaining G, viz., (1) Typhlops oligolepis, (2) 

 Zaocys nigromarcjhiatus, (3) Ahlabes sfolkzhm, (4) Dryophis fronti- 

 cincius, (5) Bungarus hwigaroides, and (6) Naia hungarus, were seen 

 in one or other of the two museums referred to above. Of the 48 

 species, two, not including the snake Bungarus niger— which remains 

 to be described in a future paper on the snakes of Assam— are new, 

 viz., Typhlopjs oligolepis and Oligodon melaneus. In 6 instances the 

 previous records of habitat have been extended, viz., Lycodon jara, 

 Ahlabes stolkzhcc, Bryo/Jiis frovticinctus, JDipsadomorphus cynodo/i, 

 Bvngarus lividus, and Bungarus niger. 



I have also tried to show justification for doubting the Eastern 

 Himalayas as within the range of distribution of one species, viz., 

 TrachiscMwn monticola (see footnote, p. 343).

Ti/ph lops jcrdoni. —Boulenger. 

 I obtained one specimen of this rare snake hitherto only known from two 

 examples, the type from the Khasi Hills, and a specimen in the Indian Museum 

 from Buxa Dooars. My specimen came from Pashok or below Tindhaiia, I 

 cannot be sure which, as some specimens got mixed. In either case it must 

 have been below 5,200 feet. It measured Oj inches. The body is depressed 

 and its transverse diameter one thirty-fourth the total length. It agrees with 

 Boulenger's description except in the breadth of the rostral which is at its 

 broadest part above about one-third the broadest part of the head. (Blgr. hardly 

 one-fourth). It is brownish-black above, dun beneath.
