229 G. A. BOULENGER ON 
4 to 44 times in length to vent in males, 44 to 5 times in females ; snout pointed, 
with sharp canthus and nearly vertical loreal region, as long as the postocular part 
of the head. Pileus twice as long as broad. Neck narrower than the head. Hind 
limb reaching the wrist in females, the elbow in males; foot as long as the head. 
Tail a little over twice the length of head and body. 
Nostril pierced between 3 to 5 shields. Rostral usually entering the nostril; 
upper head shields rugose ; frontonasal broader than long, not or but slightly broader 
than the internarial space ; preefrontals forming an extensive suture; frontal as long 
as or shorter than its distance from the end of the snout, 1} to 13 times as long as 
broad, of subequal width throughout or a little narrower behind than in front; 
parietals 14 to 13 times as long as broad ; interparietal 1} to 2 times as long as broad, 
much longer than the occipital, which may be broader. 3 supraoculars, first longer 
than the second and usually in contact with the second loreal ; 3 superciliaries, second 
longest ; no granules between the supraoculars and the superciliaries. Nasal forming 
a suture with its fellow behind the rostral and with the anterior loreal above the 
postnasal, which may be very small or absent, in which case the loreal borders the 
nostril; anterior loreal shorter than the second ; 3 or 4 upper labials' anterior to 
the subocular, which is not or but little narrower beneath than above. Temporal 
scales moderately large or rather small, hexagonal, keeled; 1, 2, or 3 large upper 
temporals, first sometimes in contact with the fourth supraocular ; a long and narrow 
tympanic shield. 
3 pairs of chin-shields, first and second in contact in the middle. 17 to 22 gular 
scales in the median line, anterior narrow, juxtaposed, smooth or faintly keeled, 
posterior increasing in size, imbricate, keeled, and merging gradually into the collar, 
the plates of which are very distinct, pointed, keeled, and 10 or 11 in number. 
Dorsal plates truncate or shortly mucronate behind, in 6 or 8 longitudinal series 
on the neck, in 4 on the body. Ventral plates obtusely pointed or shortly 
mucronate, strongly keeled, in 12 longitudinal and 22 to 25 transverse series. Sides 
with one upper and one lower series of smaller keeled scales and a median granular 
area. 26 to 28 plates and scales round the middle of the body. Preanal plate 
rather large, smooth or feebly bicarinate, bordered by a semicircle of small keeled 
plates. 
Upper surface of limbs with rhombic keeled scales. 2 or 3 femoral pores on 
each side. Subdigital lamellz single, 19 or 20 under the fourth toe. 
Caudal scales strongly keeled and mucronate, the keels forming 4 very strong 
ridges on the upper surface of the basal part of the tail ; the whorls nearly equal in 
length, the fourth or fifth containing 14 or 16 scales. 
Olive above, with a yellowish or greenish white, usually black-edged dorso-lateral 
streak starting from the superciliary edge; a dark lateral band from the nostril, 
through the eye and involving the upper half of the ear-opening, to the tail, edged 
below by a light streak. Lower parts greenish white (in spirit). Tail reddish in the 
young. 
! 3 in two specimens, 4 in two, 3—4 in the two others.
