black line from shoulder to shoulder across the back ; tail above, regu-

Description of the type. — Female. Head moderately depressed, snout 

 narrow; canthus rostralis well marked; nostrils rather large, almost 

 superior, much nearer to the tip of the snout than to the orbit; ear- 

 opening large, with four very long, triangular, pointed scales and three 

 smaller ones in front; head-shields smooth; frontal divided trans 

 versely; about eight of the posterior supraorbital scales enlarged, one 

 being particularly large, these separated from the frontals by a single 

 series of granules; superciliaries, particularly the anterior ones, very 

 long and narrow; a very long and narrow infraorbital; occipital as 

 large as ear-opening; supralabials six, and, like rostral, very wide and 

 low; infralabials scarcely higher, but considerably narrower; scales 

 on throat small, rounded, smooth, those on the middle and near the 

 edge of the gular fold somewhat larger; only one transverse gular 

 fold, not denticulated; sides of neck strongly folded; scales on back 

 and sides rather large, rounded and convex granules, those on lower 

 surface of body larger, flat, hexagonal; limbs with enlarged, keeled 

 scales, and rather long, the anterior when pressed to the side reach- 

 ing to the insertion of the thigh, the posterior when stretched forward 

 reaching to the orbit ; twenty femoral pores on each side ; tail depressed 

 at base, slender, its length more than one and three-fourths that of 

 head and body, covered with rings of rather large scales which, on the 

 upper surface and the sides, are provided with a very strong keel 

 ending in a projecting spine. 



Color above olive, more brownish on head and tail, with irregular 

 dusky, nearly blackish, cross-bands; lighter spots, or marblings, on the 

 interspaces; a very distinctly marked, straight, and intensely black band 

 from shoulder to shoulder across the back; limbs irregularly cross- 

 banded with dusky; basal two-thirds of tail pale brownish olive with 

 wide black cross-bars, terminal third uniformly blackish; under sur- 

 face greenish white, bluish on flanks with lighter dots; chin and throat 

 with a network of bluish gray. 



Dimensions. — Total length, 229 mm.; head and body, 79 mm.; tail, 

 150 mm.; fore limb, 37 mm.; hind limb, 61 mm. 



Variation. — In addition to the type Or. Mearns' collection contains 

 six other sijecimens which fully establish the characters of the species. 

 The individual variation is comparatively slight, and but few deviations 

 from the above description of the type are noticed. In some specimens 

 there seems to be a slight anterior gular fold, but it is not marked by 

 any difterence in the scutellation. In one specimen the frontal is not 

 divided transversely, and in about one-half, the large supraoculars are
