edly quadrangular, and a large, oblong shield along the an-

vertically elongated, hexagonal postnasal before the latter, in con- 
tact with the 2nd, upper labial, posterior nasal, supranasal, frontal, 
postfrontal and loreal. Hight upper labials, the seventh and eighth 
the largest, the anterior margin of the last on a line with the 
posterior angle of the eye. Seven lower labials, the last but one 
the largest. Mental like a labial, but more transversely elongated, 
with a large, azygos, pentagonal plate behind it, with the concavi- 
ties of its two hinder margins directed backwards and in contact 
with two pairs of labials, A pair of transverse shields in contact 
with the second and third labials and forming a suture together 
behind the azygos plate ; another large pair with a small azygos 
shield between the plates, succeeded by another pair with a still 
smaller pair behind the latter. Thirty rows of smooth scales 
round the middle of the body. Two longitudinal lines, in the 
middle of the back, of transversely elongated, hexagonal scales con- 
siderably larger than any of the other dorsal or lateral scales, and 
commencing from behind the occiput and diminishing in size on the 
root of the tail. Ventrals of moderate size with their posterior mar- 
gins rounded. Two large preeanals with a small external pair. Tail 
rounded, slightly, laterally compressed, long and tapering, one and 
two-thirds as long as the body, A single row of enlarged sub-caudals. 
Scales on the upper surface and sides of the tail of uniform size. 
Ear moderately large, erectly oval, with from three to four strong 
lobules on its anterior margin, the uppermost the strongest.

foot embraced by an enlarged series extending from the base of 
the first to the base of the fifth toe. Limbs well developed, 
the fore limb reaching to the tip of the snout, and the hind 
limb when stretched forwards extending to the anterior third of 
the space between the axil and groin. Seven intermaxillary and 34 
maxillary teeth in the whole of the upper jaw, and 36 in the mandi- 
ble. Seven to eight palatine teeth on either side. Snout to vent,
