Tixiaua scHLEGELIU, Gthr. (Pl. XXV. fig. C.) 
Diagnosis.— Uniform black. Scales rather large, smooth, striated, 
not keeled, in four or five longitudinal series on the back. Four 
preeanal shields, the two middle ones being the larger; a series of 
broad shields along the lower side of the tail. Ear-opening small, 
deep, round, with smooth margins. 
Hab. Sikkim. One specimen, apparently not full-grown, has been 
found at an altitude of 8930 feet. 
Description.—This species does not differ in general habit from 
the other Tiligue. Its snout is of moderate extent, and not pro- 
duced. The series of shields covering the upper surface of the head 
is as follows:—1, the rostral shield is rounded; 2, the anterior 
frontal is single, subquadrangular, broader than long ; 3, a pair of 
posterior frontals, which are not in contact with each other; 4, the 
vertical shield is quadrangular, with the anterior angle obtuse and 
the posterior very acute, and with the two anterior sides much shorter 
than the two posterior ones; the shield reaches backwards to the 
level of the pupil. 5. There are five superciliary shields on each side 
of the vertical ; 6, five occipital shields, viz. an anterior pair, a single 
central one, and a posterior pair; the anterior pair form a suture 
with the vertical, separating it from the central occipital. The latter 
is quadrangular, similar in form to the vertical, but much shorter, 
so that the anterior pair of its sides are not much longer than the 
posterior. The anterior pair of the occipitals form together with the 
central shield a perfect square. The posterior pair is obliquely 
situated, subelliptical in form, and Jarger than any of the other occi- 
pitals ; the inner side of those shields is in contact with an anterior 
and with the central occipital. 
The nostril is in a single shield between the first labial and the 
anterior frontal ; there are three shields between nostril and eye, 
covering the loreal region. Seven upper labials, the fifth of which 
is the largest, and extending upwards to the eyelid. The posterior 
part of the orbit is formed by three small shields, behind which are 
some large temporals. The median lower labial is broader than 
long, truncated posteriorly, forming a straight transverse suture 
with another single broad shield situated immediately behind the 
median labial. There are five narrow lower labials, with an interior 
series of five other much larger shields ; the remainder of the throat
