1879.] W. T. Blanford—Wotes on Reptilia. 131 
The specimen is 12 inches long, of which the tail measures 1. It was 
collected by Dr. Baker in Pegu, I believe, in the neighbourhood of Bassein, 
and sent to me with some other snakes for examination by Captain Spear- 
man. 
This Hypsirhina appears separable from all other species by the larger 
number of rows of scales. The scales in this genus are so regular, that I 
think even a single specimen affords sufficient evidence of distinction, and 
the Pegu snake is further distinguished from H. chinensis, its nearest ally, 
by having a smaller number of ventral shields. In H. chinensis there are 23 
rows of scales round the body and 150 ventrals. I have not access to a 
specimen of H. chinensis, and so far as I am aware no figure of this species 
has been published, so I cannot tell whether H. maculata has a differently 
formed head. From the two species of Hypsirhina previously recorded 
from Burma and India, H. plumbea and H. enhydris, the present form is 
at once distinguished by its much blunter muzzle and smaller prefrontal 
shield, and by its coloration, besides the much more numerous rows of 
scales. 
DIPsaS TRIGONATA. 
A young snake, obtained by Major Mockler at Gwadar in Baluchistan, 
appears to me to be nearer to this species than to any other, although I can- 
not feel sure that it is correctly identified, for, although I can detect no 
distinction in the shields, the head appears narrower, less triangular, and 
peculiarly coloured, and the muzzle broader than in other examples of the 
species. The locality is of interest also, as it is much farther west than 
this snake has been previously found, Gwadar being about 200 miles west 
of the British frontier, and the occurrence on the Baluchistan coast shews how 
thoroughly terrestrial a form this species of Dipsas is, for there is nota 
single tree and scarcely a bush to be found near Gwadar, which is merely a 
fishing village on a barren spit of sand, between a rocky promontory and 
the mainland. 
The length of the specimen is 12 inches, of which the tail is 24. 
Ventrals 230, subcaudals 92. The upper surface andside of the head are 
mottled with black, which prevails in front, so that the frontals, rostral, and 
anterior labials are entirely black or blackish. On the body there are the 
usual rather irregular transverse dark-edged whitish elongated spots. 
XENURELAPS BUNGAROIDES. 
This snake has hitherto only been reported from the Khasi hills, 
where it appears to be rare.* In 1878, I captured a specimen close to Dar-
