Head and body moderately depressed. Head 1^ times as long as 

 broad, its length 4 times in length to vent ; snout pointed, the nasals 

 not swollen, as long as the postocular part of the head; canthus rostralis 

 obtuse; cheeks swollen. Pileus twice as long as broad. Neck a little 

 constricted. Hind limb hardly reaching the axil; foot scarcely longer 

 than the head; toes rather short, not compressed. Tail 1^ times as 

 long as head and body, flattened at the base. 



Upper head-shields smooth ; nasals in contact behind the rostral, the 

 suture between them ^ the length of the frontonasal, which is broader 

 than long; four prefontals, outer narrow, baud-like, between the fronto- 

 nasal, the normal prefrontal, and the second loreal; frontal nearly as 

 long as its distance from the end of the snout, If times as long as 

 broad, f of its lateral border in contact with the large supraoculars ; 

 parietals longer than broad ; interparietal much smaller than the fronto- 

 parietals ; no occipital. Two large supraoculars, preceded by 3 or 4 

 small shields and followed by a small shield ; the first of the two large 

 supraoculars as long as the second and longer than its distance from 

 the second loreal ; a series of granules between the supraoculars and 

 the superciliaries. Rostral large, broader than deep ; four nasals, the 

 lower being divided, extensively in contact with the rostral, and 

 resting on the first three upper labials ; anterior loreal deeper than 

 long, shorter than the second; subocular not reaching the mouth, 

 resting on the 6th to 8th upjjer labials. Temjioral scales hexagonal, 

 smooth, upper very small, lower larger; tympanic shield present; no 

 auricular deuticulatiou. Lower eyelid opaque. 



5 pairs of chin-shields, the 3 anterior in contact in the middle ; 36 

 gular scales in a straight line between the symphysis of the chin-shields 

 and the median collar-plate ; gular fold distinct. Collar curved, free, 

 serrated, composed of 11 plates. 



Scales granular, smooth, 54 across the middle of the body. Ventral 

 plates in 16 oblique longitudinal and 30 angular transverse series ; 

 these plates mostly longer than broad. Preanal region covered with 

 numerous small plates. 



Upper surface of arm with small smooth scales. Scales on upper 

 surface of tibia similar to dorsals an outer series of large shields on 

 the lower sui'face. 12 or 13 femoral pores on each side, the two series 

 widely separated in the middle. 



Scales on upper surface of base of tail smooth or feebly keeled, on 

 lower surface smooth.
