444 F. Stoliczka — On Indian and Burmese Ophidians. [No. 4, 



recently received a third specimen of this species from the Anda- 

 nians, whence most probably the two type specimens referred to 

 were received. 



The characters of the species may be put as follows : 



Head very distinct from neck, broad and flat above, a pair of 

 supra-rostals, separated by an azygos shield, about equal in size 

 to one of the former ; supraciliaries narrow, long ; scales of the 

 head small, slightly carinate on the posterior part : there are from 

 10-12 of them in an irregular line between the supraciliaries ; scales 

 of body in 25 long, rows, small, imbricate and sharply keeled 

 throughout ; 2nd labial forms the front of the pit, but some- 

 times the upper portion is partially or entirely detached; 11 or 12 

 upper labials ; two rows of scales between labials and orbit ; eye 

 rather large. The two type specimens which are nearly full 

 grown, have each 182 ventrals, 56, the other 71 sub-caudals; 

 anal entire, strongly projecting. The third specimen which mea- 

 sures only 11 inches, has 181 ventrals and 57 sub-caudals. 



The general colour of the snake is dark brown ; when young it has 

 numerous greenish transverse bands on the body, each about 2 scales 

 wide, and about 3 or 4 scales apart from each other ; the sides of the 

 head and the lower side of the body are irregularly marbled and 

 spotted with greenish white. In the more adult stage, the light 

 bands become interrupted on the back which is nearly uniform 

 brown, like the head, but the greenish colour is preserved in more 

 or less numerous and irregular spots at the sides. 



Dr. Anderson in his notes on Indian Eeptiles, published in 

 the Proceedings of the Zool. Soc. of London for 1871, p. 194, 

 says that Trim. Andersoni is identical with Trim, monticola. 

 Few species could be more distinct from each other than these. 

 T. Andersoni is a much slenderer snake, has comparatively 

 smaller and more sharply keeled scales in 25 rows, narrow super' 

 ciliaries with 10 or more scales between them on the upper side of 

 the head, 11-12 upper labials, those after the third becoming rapidly 

 smaller and superseded by scales which are not larger, but generally 

 somewhat smaller than the labials ; all three known specimens have 

 on azygos shield, above 180 ventrals and a large eye. The colour is
