 covered 'wdth somewhat enlarged and slightly bulging scales; the 

 temporal region between this ridge and the ear covered with uniform

 point below the center of the eye; symphysial large, semicircular, 

 partially divided by a suture posteriorly; a row of four or five 

 enlarged scales just belov/ the infralabials, merging gradually with the 

 thi"oat scales, which are tubercular and nonimbricate ; gular fan very 

 large, the inner portion appearing nearly naked but really covered with 

 very indistinct and small scales, the outer bordered with very small 

 but distinct scales, which are imbricate. A dorsal crest of one row 

 of mucronate scales beginning just beliind the occiput, continuing 

 along the back, becoming greatly diminished at the beginning of the

 single, oval, tubercular scales separated by two or three rows of ex- 

 ceedingly minute, granular scales; belly covered with smooth imbricate 

 scales about as large as the lateral "tubercles" into which they merge 

 insensibly; upper parts of arms and legs with large, hexagonal, keeled 

 scales; sides of tail with regularly arranged rows of small rectangular 

 scales, each bearing a low median keel; scales beneath the tail con- 

 siderably larger, hexagonal and sharply keeled; male with enlarged 

 postanal plates; about 33 lamellae under the enlarged portion of the 

 fourth toe.
