Head cuneiform, with the nose and frontal region depres- 

 sed; the occiput twice as high as the nose and the greatest 

 breadth of the head more than twice the breadth of the 

 snout. Snout long, obtuse, twice the diameter of the orbit. 

 Forehead rather concave. Body somewhat compressed, the 

 vertebral region feebly keeled; tail depressed, tapering to 

 a curved point (prehensile?). Limbs short and flat, a httle 

 overlapping, when adpressed; the hind ones very broad, with 

 a dermal fold along the inner side. Fingers and toes clawed^ 

 entirely dilated, inferiorly with undivided, curved lamellse, 

 9 — ^10 on the fourth finger and toe. Except thumb and inner toe 

 the distal joint of the toes completely resembles the figur e 

 7 b given by Boulenger of the toes in E. vieillardi, viz. 

 the joint being narrow and compressed and appearing as a 

 distinct median ridge upon the dilated inferior pad. On the 

 inner toe and on the thumb such ridge is not to be found; 

 instead of that there are a few rather enlarged median scales.. 

 the distal of which being largest and nail-like, covering the ex- 

 tremely small claw. Inferiorly this one is also ensheathed 

 by two enlarged lateral scales. On the other toes and fin- 

 gers the claws are large, not retractile. 



Scales on the back and sides rather large, round, and juxta- 

 posed, becoming smaller on the neck, the narrow intervals for- 

 ming a fine network; on the belly the scales are smaller and 

 somewhat imbricate ; about 60 scales round the middle of the 

 body; the scales on the upper and lower parts of the limbs and 

 on the upper base of tail as on the body. Scales on the other 

 parts of the tail are squarish, large and juxtaposed arranged in 

 verticils; 32 scales in the first annulus On the throat the 

 scales are very small, sharply defined from the larger ones on 

 the belly, which they resemble in other respects. 



The upper surface of the head is covered with symme- 

 trical plates : a broad and low septagonal rostral with a me- 

 dian cleft above, two nasals, separated by an internasa], 

 longitudinally enlarged; two large prsefrontals, broadly in 

 contact with eachother and separated from the internasal by 

 a small azygos prsefrontal; a short and broad pentagonal 

 frontal; a frontoparietal, parietals, and an interparietal, all 

 broken up in regularly arranged smaller plates; one upper 

 and one or two very small lower postnasals; two loreals. The 

 eyes encircled with small granules; the upper eyelid also
