 transparent disk ; ear-opening oval, larger than the palpebral 

 disk, with two or three small lobules anteriorly. Nostril between 

 three small shields, a nasal, a postnasal and a supranasal; 

 frontonasal more broad than long, broadly in contact with the 

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

 parietal, narrower, in contact with the two anterior supra- 

 oculars; five supraoculars, last very small; seven supraciliaries; 

 frontoparietals and interparietal fused ; parietals in contact 

 behind the latter shield ; a pair of nuchals and a pair of tem- 

 porals; four labials before the large subocular. Body slender; 

 30 — 34 smooth scales round the middle, dorsals largest, trilin- 

 eated, laterals smallest; praeanals a little enlarged. Tail twice 

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

 the axilla; digits moderate, basal part rounded, distal com- 

 pressed; fourth toe with 33 — 40 smooth lamellae below. 



Olive-brown above, head and nape paler and usually uniform ; 

 back with blackish spots, often arranged in a double line on 

 each side, sometimes separated by lighter coloured spaces; 

 a light dorso-lateral streak, beginning above the eye, to the 

 hind limbs; tail and limbs olive, with pale and black spots; 

 flanks black with a pale streak from axilla to groin and pale-
