Fig. 9.—Enhydrina valakadyn (nat. size). 
The type-specimen, which had previously been lost sight of, I discovered in the 
Royal College of Surgeons’ Museum, London. It is No. 523 of their catalogue (1859, 
p. 78), and is the original specimen from Tranquebar figured by Russell in his second 
volume, plate xi. It was one of Russell’s collection which was presented to the 
above Institution by the East India Company, most of which has since been trans- 
ferred to the British Museum. 
I do not concur with Boulenger in thinking plate x. of Russell’s same volume 
a distinct species. I think there can be no doubt that this figure represents the same 
species as plate xi, viz. valakadyn (Boie), a view I may state taken by many 
other herpetologists. If this assumption is correct, and I cannot think otherwise, this 
species should rest under the title given it by Daudin in 1803, viz., schistosa, 
and Boie’s valakadyn should be suppressed. I have examined a very large series 
of this species. In Cannanore on the Malabar Coast of India the fishermen brought 
them to me in bucketfuls, and I have frequently seen a dozen or more in a net at one 
haul on the Coromandel Coast (Gopalpore). It isa very easy snake to identify. 
The downward projection of the rostral and the groove in the symphysis menti are to 
be seen in no other sea snake. 
Description.—R ostral,—touches four shields ; the portion visible above is one- 
third or less than one-third the internasal suture. Praefrontals,—touch the 
second supralabial (except in rare examples where they fail to touch any).
