flat granular scales, aud large trihedral tubercles arranged in 16 to 

 20 more or less irregular longitudinal series ; these tubercles vary 

 somewhat in size according to specimens, but the largest never 

 exceed two fifths the diameter of the eye. Abdominal scales 

 large, smooth, rounded, imbricate. Males with a series of pra?anal 

 pores, interrupted mesially ; 6 to 8 pores on each side. Tail 

 rounded, feebly depressed, tapering, covered above with irregular, 

 small, smooth imbricated scales and rings of large, pointed, keeled 

 tubercles, beneath with a median series of transversely dilated 

 plates. Light pinkish brown above, generally with more or less 

 defined transverse darker bands bordered by pure white tubercles 

 surrounded by deep-brown rings ; young very regularly barred 

 with dark brown, there being four dark bars between head and hind 

 limbs ; a more or less defined dark-brown streak, white-edged 

 above, on the side of the head, passing through the eye ; lower

Differs from H. triedrus in the following points : Head more 

 depressed. Infradigital lamellaB more numerous, 10 under the

Head oviform ; snout longer than the distance between the eye 

 and the ear-opening, lj to 1^ the diameter of the orbit ; forehead 

 concave ; ear-opening oblique, nearly half the diameter of the eye. 

 Body and limbs moderate. The skin forms a fold on each side of 

 the belly, from axilla to groin. Digits distinctly webbed at the 

 base, moderately dilated, inner well developed, with curved, scarcely 

 oblique lamella ; 7 (or 6) under the inner digits, 9 or 10 under the 

 median fingers, 10 or 11 under the median toes. Snout covered 

 with granular scales, largest in front of the orbits ; hinder part of 

 head with minute granules intermixed with round tubercles. 

 Eostral subquadrangular, not twice as broad as deep, with median 

 cleft above ; nostril pierced between the rostral, the first labial,
