parietals form a suture; fifth and sixth upper labials largest and 
entering the orbit; a very large azygos postmental. Tympanum 
smaller than the eye-opening. 30 scales round the middle of the 
body, all smooth ; ventrals largest. A single large plate covers the 
preanal region. The hind limb reaches the wrist or a little beyond. 
Subdigital lamelle smooth. Tail slightly compressed, once and two 
fifths the length of head and body; scales smooth. Rufous-brown 
above, with darker transverse bands or large alternating spots on 
the back, the paler ground-colour sometimes appearing as a series 
of rhombs along the back; sides with whitish spots ; lower surfaces

Upper head-shields feebly rugose ; a single frontonasal, nearly as 
broad as long; prefrontals forming a median suture (separated, 
probably abnormally, in the type specimen); frontal as long as 
frontoparietals and interparietal together; five supraoculars, first 
longest, fifth very small; supracilieries becoming very minute and 
indistinct posteriorly, altogether about fourteen; frontoparietals 
shorter than the interparietal; parietals in contact behind the in- 
terparietal ; fifth and sixth upper labials largest and entering the 
orbit; an azygos postmental. Tympanum smaller than the eye- 
opening. 32 scales round the middle of the body; dorsals and 
laterals equal, strongly keeled, with rounded posterior border, the 
keels forming continuous straight lines (eight in number) on the 
pack, and oblique ones on the sides; ventrals largest and smooth. 
A single large plate covers the preeanal region. The hind limb 
reaches the elbow or the axilla. Subdigital lamelle smooth. Tail 
strongly compressed, nearly twice as long as the body, inferiorly 
with a series of large transverse scales ; upper caudal scales keeled, 
like the dorsals. Brown above, with darker and lighter spots; sides 
dotted with blackish and white; lower surfaces whitish, the tail 
dark brown. :
