218 Indian and Malayan Amphibia and Reptilia. [No. 3, 



well developed, white, margined with coral red below, or it is absent ; 

 tail pale ruddy above, usually equal to one-sixth of the total length. 



One specimen from Moulmein measures 27 J inches, of which the 

 tail is 4£, scales in 23 rows, ventrals 155, subcaudals 51, one azy- 

 gous shield. A young specimen from the hills, N. E. of Simla (about 

 6000 feet) is llf inches, of which the tail is 2£, ventrals 163, sub^ 

 cauclals 74, the fifth and ninth being entire. An other adult 

 specimen from the same locality has no azygous shield, it measures 

 35£ inches, of which the tail is 5 J ; ventrals 173, subcaudals 62 ; on 

 the neck there are 22, round the middle of the body only 21 series 

 of scales, the reverse being often the case in other specimens. 



Three specimens, in the Asiatic Society's collection, from Bengal, 

 each has 25 rows of scales, they are uniform green. It is very 

 difficult to distinguish some specimens of this species from grami- 

 neus, especially when the number of rows of scales is as low as 2 1 ; 

 such specimens could be referred to either of the species r the only 

 criterion in favor of carinatus being the short and rather broad, stout 

 head, and the large size of the supraciliaries. 



I have not seen any typical specimens of carinatus from the Anda- 

 mans, those which have been referred to it appear to be really 

 distinct and belong to the next species.

Body rather slender with a large elongately triangular head ; scales 

 usually in 25 series, narrow, elongated, sharply pointed and cari- 

 nated ; supranasals small with one large azygous shield between 

 them ; supraciliaries narrow, as in gramineus ; upper labials 12-14, 

 the posterior nine or ten markedly small, the second forms the 

 front of the facial pit ; scales on the head keeled, all of moderate 

 subequal size, those on the front part flattened.

 rowly projecting, semilunar, entire ; subcaudals 55.
