opening oval, larger than the palpebral disk, with small lobules 

 all round its border. Nostril in the nasal; no supranasals; 

 frontonasal much more broad than long, forming a broad suture 

 with the rostral and a narrow one with the frontal ; latter a 

 little shorter than the frontoparietal, in contact with the two 

 anterior supraoculars; four supraoculars; seven supraciliaries; 

 frontoparietal single; interparietal small, but distinct; parietals 

 in contact behind the latter; a pair of nuchals and a pair of 

 temporals ; four labials before the subocular. Body with 42 scales 

 round the middle, dorsals and laterals distinctly tricarinate; 

 the distance between the tip of the snout and the fore limb 

 is contained one time and one fourth in the distance between 

 axilla and groin ; praeanals feebly enlarged. Tail nearly twice 

 as long as head and body. Limbs strong, the hind limb reaches 

 beyond the anterior side of the fore limb ; fingers four, toes 

 five; fourth toe with 32 lamellae below. 



Dark brown above, with two crossing, irregular lines of light 

 spots, some of which have black centres; flanks with a dark 

 band, broken up into squarish blotches by white vertical lines. 

 Tail with two light longitudinal stripes, edged above with 

 brown, below with yellow. Lower parts yellowish. Length 

 of head and body 5 1 mm.; tail 90 mm. (After Barbour, not 

 seen by me).

Snout obtuse; lower eyelid with a transparent disk; ear-

 lobules round its border. Nostril in the nasal; no supranasals; 

 frontonasal more broad than long, broadly in contact with the 

 rostral, narrowly with the frontal ; latter as long as the fronto- 

 parietal, in contact with the two anterior supraoculars ; four 

 supraoculars, second largest; eight supraciliaries; frontoparietal 

 single, fused with the interparietal; parietals in contact; a pair 

 of nuchals and a pair of temporals; four upper labials before 

 the subocular. Body with 34 — 38 scales round the middle, 

 dorsals largest, smooth or with three low keels; the distance 

 between the tip of the snout and the fore limb is contained 

 one time and one sixth to one time and one third in the
