supraorbitals by three or four rows of scales ; canthus rostralis 

 angular, cantbal scales three or four ; loreal rows five or six ; six 

 or seven upper labials to below the centre of the eye ; ear-opening 

 rather large, oval. Gular appendage large, merely indicated ni 

 the female ; gular scales smooth. Body feebly compressed ; no 

 dorso-nuchal fold. Dorsal scales very small, granular, keeled, a 

 little larger than the granules on the flanks ; ventral scales larger 

 than dorsals, juxtaposed, smooth. The adpressed hind limb reaches 

 the eye on the posterior border of the orbit ; digits rather feebly 

 dilated; 17 or 18 lamella under phalanges ii. and iii. of the 

 fourth toe. Tail roundish, covered with strongly keeled scales 

 without enlarged dorsal series ; length of tail about twice that of

 Ecuador.

Head twice as long as broad, as long as the tibia ; forehead 

 concave ; frontal ridges short and feeble ; upper head-scales feebly 

 keeled ; scales of the supraorbital semicircles large, separated by 

 a single series of small scales on the vertex ; 11 or 12 enlarged, 

 keeled supraocular scales, separated from the supraorbitals by one 

 series of granules ; occipital not quite so large as the ear-opening, 

 separated from the supraorbitals by three series of scales ; canthus 

 rostralis angular, canthal scales three ; loreal rows five ; six upper 

 labials to below the centre of the eye ; ear-opening moderately 

 large, roundish. Gular appendage very large; gular scales 

 smooth. Body compressed ; no dorso-nuchal fold. Dorsal scales 

 very small, granular, scarcely larger than the laterals : ventrals 

 larger, small, granular, smooth. The adpressed hind limb reaches 

 the eye ; digits moderately dilated ; 22 lamellfe under phalanges
