Snout short, obtuse. Xasal small ; postnasal present or absent ; 

 Bupranasals sometimes in contact with the praet'rontals : five supra- 

 oculars, the two or three anterior in contact with the frontal ; 

 parietals entirely separated hy the interparietal ; one or two pairs of 

 nuchals ; seventh upper labial largest ; ear-opening nearly as large 

 as a dorsal scale, without distinct lobules ; two azygos postmentals. 

 28 scales round the body, the laterals smaller than the others. When 

 pressed against the body the limbs meet or fail to meet ; the length 

 of the hind limb enters thrice to thrice and one third in the length 

 from snout to vent. A series of transversely enlarged subcaudals. 

 Pale olive above, all or part of the scales edged with dark brown, 

 sometimes with rather indistinct longitudinal dark bands ; lower 

 surfaces greenish white.

Apparently closely related to E. obsohtus. Supranasals in contact 

 with the prajfrontals : no postnasal. The limbs do not meet when 

 pressed against the body. Subcaudal scales not enlarged. Olive 

 above, with four equidistant and equal dark stripes ; two narrow 

 white lines on each side, traversing the centre of single rows of scales, 

 and margined above and below by black : upper lateral light lines 

 separated by six rows of scales ; beneath light greenish.
