EUPREPES OLIVIERII. 
head, body, and tail, the lips, and the inner surface of the extremities, pale 
sienna-yellow ; the outer surface of the extremities the colour of the back, 
and finely speckled with yellowish brown. In young individuals the brown 
of the back is paler and brighter than in adults, and the dark spots are less 
regularly placed ; on many the white vertebral line is scarcely visible ; in 
some the lower part of the sides has a vermilion-red tint. Fig. 3 shows the 
colours of an adult female, 4 of a young female, and 5 of a young male. 
Form, &c. — Figure moderately robust. Head four-sided, tapered to the 
nose; body rather depressed; the back slightly arched, the sides rather 
protuberant ; abdomen flat. Tail at and near the base subquadrangular, 
elsewhere cylindrical, and tapered to the point, which is slender and acute. 
The head, superiorly, is sloped to the nose, which is narrow and rounded. 
Nostril small, circular, and situated in the nasal plate. Eyes rather small ; 
eyelids externally granular, the lower lid with a semi-transparent central 
disc. External ear-opening oblique and narrow, its lower extremity in a line 
with the angle of the mouth, and its anterior edge fringed with two or three 
narrow, projecting, pointed scales. The anterior and posterior extremities 
rather slender and subcylindrical ; toes long and delicate, the fourth toe of 
the hinder foot much the longest; claws slender, much curved, and pointed. 
Rostral plate subtriangular, its apex rounded ; supra-nasal plates narrow and 
anteriorly contiguous. Naso-rostral plate sub-rhomboidal, longest trans- 
versely, the anterior margin more or less arched. Fronto-nasal plates 
subquadrangular, not contiguous. Frontal plate sub-rhomboidal, the two 
anterior much shorter than the posterior sides. Fronto-parietal plates 
subquadrangular or five-sided. Parietal plates five-sided; interparietal 
plate rhomboidal, the two hindermost sides longest. Palpebral plates four, 
the second the largest. Frenal plates, two, quadrangular; naso-frenal small 
and subtriangular. Plates of upper lip, exclusive of rostral, and of lower, 
exclusive of mental, seven ; the fifth of the former much the longest. Scales 
of the body and tail rather small, and somewhat six-sided, the posterior 
sides often short and arched ; those of the back and sides, upper and lateral 
surface of tail, and of the outer parts of the extremities, three keeled, the 
keels on the back and the base of the tail strongly developed ; pre-anal plates 
seven or eight in an arched row. Between each parietal plate and the dorsal 
scales, a long, nai’row, transverse plate. Length from nose to base of tail, 
in the smaller individuals, figured 1 inch 6 lines to 1 inch 10 lines; in the 
larger, 2 inches 4 lines ; length of the tail in the former, 2 to 2| inches, 
in the latter, 3 to 4 inches.
