a smaller dewlap, narrower digital dilations, and fewer lamellae under 

 the second and third phalanges of the fourth toe. It also differs in 

 coloration. Possibly it will eventually be found that some of the 

 characters enumerated above are not constant. 



"Description. — Head almost twice as long as broad, longer than the 

 tibia; forehead concave; upper head scales very small, sharply keeled, 

 some multicarinate; scales of supraorbital semi-circles enlarged, sepa- 

 rated by three rows of scales; approximately nine, enlarged, keeled, 

 supraocular scales, separated from the supraorbitals by a row of 

 granules; occipital about the same size as the ear opening, separated 

 from the supraorbitals by four series of scales; can thus rostralis 

 distinct, can thai scales five; loreal rows seven or nine; seven upper 

 labials to below the center of the eye; ear opening suboval; gular 

 appendage small, gular scales keeled; body compressed; no dorso- 

 nuchal fold; dorsal scales granular, decidedly enlarged and keeled on 

 the vertebral line; ventral scales rather small, much larger than the 

 granular dorsals, subimbricate, and strongly keeled; the adpressed 

 hind limb reaches beyond the eye; digits rather feebly keeled; seven- 

 teen lamellae under phalanges two and three of the fourth toe; male 

 with enlarged postanal scales. 



''Coloration in alcohol. — Dorsum dark gray; upper side of limbs, 

 head, and base of tail, grayish brown. Dorsum, base of tail, and 

 limbs, with darker cross-bands above, those of the dorsum and fore 

 limbs barely discernible, while those of the hind limbs and base of tail, 

 though faint, are readily visible ; belly gray; under sides of limbs yellow-
