canthals by a series of fairly large scales; two rather small can thai 

 scales, the first one a little shorter and wider than the second, which is 

 followed by five superciliaries, the third the longest, tlie last two 

 rather small ; six blimtly ridged supraociilars,separated from the frontals 

 by a single row of keeled scales and from the superciliaries by two rows 

 of scales except in the anterior portion where the prolongation of the 

 first superciliary crowds out part of the second row of separating 

 scales; frontals moderate in size, mutually in contact along their 

 entire inner border; occipital small, bordered on each side by two 

 distinct parietals, the inner a little smaller than the outer, which is 

 almost twice as large as the occipital; four upper and five lower 

 labials to a point below the center of the eye; temporal scales rather

irregular in size anteriorly, the lower ones smooth but swollen, 

 the upper ones blimtly keeled, with a single slightly enlarged 

 scale above the ear; anterior border of the ear with five unequal 

 projecting scales, the longest reaching to halfway across the tympa- 

 num. Dorsal scales small, imbricate, mucronate; laterals very much 

 smaller than the dorsals, the gradation in size being rather rapid; 

 ventrals somewhat larger than the dorsals, smooth, their posterior 

 borders scarcely denticulate; about 88 dorsal scales from the occiput 

 to a point directly above the vent; about 20 dorsal scales equivalent 

 to the distance from snout to occiput; nuchal scales small, those 

 behind the ear very minute and sharply tubercular; those in the 

 shoulder folds keeled like the dorsals but rather small; a distinct 

 lateral fold present. The adpressed hind lunb reaches to the center 

 of the eye. Digits compressed, the fourth toe with 25 tricarinate
