Description. — Body long rather slender, with short 

 limbs and very long tail. Head pointed, with flat top and 

 nearly vertical sides, its temporal regions bften greatly 

 swollen in old individuals. Rostral plate rounded in upper 

 outline. On top of head, behind rostral, a pair of small 

 internasals, a pair of small frontonasals, a very large azy- 

 gous prefrontal, a pair of large prefrontals, a long frontal, 

 a pair of frontoparietals, two parietals separated by an inter- 

 parietal; a pair of occipitals, and an interoccipital. Two 

 series (of five and three) supraoculars and a series of small 

 superciliaries. Temporal scales keeled, lower sometimes 

 only weakly. Upper labials much larger than lower. Two 

 series of large sublabial plates below infralabials, lower 

 larger. Gular scales smooth and imbricate. Scales on arm 

 and forearm keeled. Scales on upper surfaces and sides of 

 neck, body and tail large, rhomboidal, slightly oblique, 

 strongly keeled, strengthened with bony plates, and ar- 

 ranged in both transverse and longitudinal series. Number 

 of longitudinal dorsal series 12 2^2 or 14 (rarely 12 or 

 14 2/2). Number of transverse series between interocci- 

 pital plate and backs of thighs varying at least from 42 to 

 43. A band of granules along each side from large ear- 

 opening to anus, usually hidden by a strong fold. Ventral 

 plates about size of dorsals, smooth, imbricate and arranged
