is covered with scales like the belly. The opening of the ear is small, 
round, and deep. 
The scales are finely striated, without keels, and rather large on 
the back, whilst those on the belly are of moderate size, and those 
on the sides rather small. I count in the middle of the trunk five 
longitudinal series on the back, seven on each side, and six on the 
belly ; so that that part of the body is surrounded by twenty-five 
series. There are four preeanal shields, the middle pair being con- 
siderably the largest. » 
The greater portion of the tail is broken off; a band of broad 
shields begins to cover its lower side at a short distance from its 
origin ; the tail is surrounded by eight series of scales, which exhibit 
no keel whatever. The tail itself is rounded, not compressed, and 
tapering. 
The extremities are covered with scales similar to those of the 
body ; the fore extremity reaches to the anterior margin of the eye, 
if laid forwards; the third and fourth fingers are the longest, and 
nearly equal ; then follow the second, the fifth and the first. The 
length of the hinder extrémity is rather more than one-half that of 
the trunk ; the fourth toe is the longest ; the third and fifth are equal 
in length, and the first is shorter than the second. All the fingers 
and toes are slightly compressed and well armed with claws. 
The upper parts are uniform black, the lower ones blackish. 
Palatine teeth none.

Diagnosis.— Scales in fifteen rows; six upper labials, the third 
and fourth of which enter the orbit; Above uniform blackish ; 
below yellowish. 
Hab. Sikkim (5340 feet above the level of the sea). Another 
specimen, sent by Mr. Hodgson from Nepal, and rather injured, is 
in the Collection of the British Museum. 
Description.—The head is of moderate length, and continuous 
with the neck ; the body and tail are rather slender. The rostral is 
a little broader than high, rounded superiorly, and reaching to the 
upper surface of the head. . The anterior frontals are smaller than 
the posterior ones, which are bent downwards to the side of the head. 
The vertical is not twice as long as broad, and has the posterior
