 rate ; digits slightly depressed at the base, compressed in the remain-

 phalanx. Head covered with very small granular scales ; rostral

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

 labial, two nasals, and two or three granules ; seven or eight upper

 labials, generally with a pair of chin-shields posteriorly ; no other 

 chin-shields. Upper surfaces covered with very small granules ; 

 back with sixteen to twenty longitudinal series of round, sub- 

 conical, distinctly ribbed tubercles ; these series regular, equidistant, 

 the tubercles generally very close together, forming lines ; hind 

 limbs with similar, irregularly scattered tubercles. Gular scales 

 minute, granular ; abdominal scales very small, imbricate, keeled. 

 Males generally with a very short angular series of seven or eight 

 praeanal pores. Tail cylindrical, tapering, generally with uniform 

 very small keeled scales, occasionally intermixed with large tu- 

 bercles. Brown, lighter beneath ; back and limbs with more or less
