between them and the supraoculars ; parietals as long as broad ; inter- 

 parietal smaller than the frontoparietals, in contact with the small 

 occipital, or separated from it by a small shield ; 3 large supraoculars, 

 forming sutures with each other, the first as long as or a little shorter 

 than the second and in contact with the frontonasal, the second loreal, 

 and the fii-st superciliary ; tliird supraocular followed by a granular 

 area ; one (rarely two) series of granules between the second and 

 third supraoculars and the superciliaries, which are 6 to 8 in number, 

 first longest. Lower nasal broadly in contact with the rostral, resting 

 on tlie first and second (rarely also third) upper labials ; anterior 

 loreal longer than deep, shorter than the second ; subocular strongly 

 keeled below the eye, resting on the 5th to 7th, 6th to 8th, or 6th to 

 9th upper labials, forming a very obtuse angle between the 6th and 

 7th, 7th and 8th, or 8th and 9th, its antero-inferior border much 

 longer than the postero-inferior. 2 to 4 small, keeled upper temporals ; 

 temporal scales granular, smooth or obtusely keeled ; tympanic shield 

 usually present; 2 or 3 obtuse projecting lobules in front of the ear. 



5 or 6 pairs of cliin-shields, the 3 first meeting in the middle. 32 

 to 43 gular scales in a straight line between the symphysis of the 

 chin-shields and the median collar-plate ; no gular fold. Collar 

 straight or slightly curved, with 12 to 17 small pointed plates. 



Scales granular, smooth or obtusely keeled ; a narrow band 

 of larger, rliomboidal, keeled scales on each side of the posterior part of 

 the back and of the sacral region; 78 to 92 scales across the middle 

 of the body. Ventral plates as long as broad, tessellated or forming 

 oblique longitudinal series, in 35 to 39 transverse series, the longest of 

 which contains 22 to 26 plates. Preanal region covered with small 

 irregular plates, or with an enlarged postero-median plate. 



Upper surface of arm witli rather large, rhombic, obtusely kealed 

 scales. Upper surface of tibia with rhombic feebly keeled scales, 

 which are a little larger than the dorsals ; lower surface with one row 

 of transversely enlarged plates and 2 or 3 rows of smaller plates. 27 

 to 37 femoral pores on each side, the two series narrowly separated in 

 the middle. Fingers with 4 series of scales, symmetrically and rather 

 strongly serrated on each side, feebly unicarinate beneath ; toes with 

 3 series of scales, the outer forming a rather strong fringe, the 

 subdigital lamellse strongly keeled and 22 to 28 in number under the 

 fourth toe. 



Upper caudal scales rhombic, keeled, lower, at the base of the tail, 

 smooth or obtusely keeled ; a broad band of granules, continued from 

 the back, along the middle of the base of the tail; 46 to 52 scales in 

 the fourth or fifth whorl behind the postanal granules.
