snout pointed, with the nasal shields feebly swollen, a little lon<;-ei' 

 tha,n the postocular part of the head, with sharp canthus and feebly 

 concave loreal region ; a distinct concavity in the middle of the upper 

 surface of the snout, extendint;- to the middle of the frontal shield. 

 Pileus 2J to 2]y times as Ioiil;- as broad. Neck as broad as tlie head or 

 a little constricted. Himl limb leaehing the ear or the eye in males, 

 between the collar and the ear or between the ear and the eye in 

 females; foot Ifr to 1§ times as long as the head; toes rather slender, 

 feebly compressed. Tail 2 to 2i^ times as long as head and bod}'. 



Upper head-shields flat, smooth. Nasals in contact with each other 

 behind the rostral, the suture between them \ to \ the length of the 

 frontonasal, which is as long as broad or a little bi'oader than long; 

 prefrontals as long as broad or longer than broad, usually forming a 

 median suture* ; frontal shorter than its distance from the end of the 

 snout, 1-^ to If times as long as broad, i to f of its lateral border in 

 contact with the large sujiraoculars ; parietals \\ to H times as long 

 as broad; interparietal larger than the frontoparietals, in contact with 

 the large but shorter occipital. Two supraoculars, the first as long as 

 or longer than its distance from the anterior loreal, the space in front 

 of it filled by 6 to 15 scales or granules ; 6 or 7 superciliaries, first 

 longest, separated from the supraoculars by one or two, nearly threef 

 series of granules. Three nasals, lower in contact with the rostral and 

 the first upper labial, postei'ior small ; anterior loreal \h to 2 times as 

 long as deep, shorter than the second ; 5 or 6, rarely 4, upper labials 

 anterior to the subocular, which is keeled below the eye and largely 

 borders the mouth, its lower border much shorter than the upper. 

 Temporal scales granular, smooth ; a narrow tympanic shield ; auri- 

 cular deuticulation absent, or reduced to a few projecting granules. 

 Lower eyelid with a transparent disc formed of 2, rarely 3 or 4, 

 larger black-edged scales, with 2 to 4 smaller ones below. 



4 pairs of chin-shields, the first three in contact in the middle. 

 27 to 35 gular scales in a straight line between the symphysis of the 

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

 free, composed of 9 to 15 plates. 



Scales juxtaposed, granular, smooth, larger towards the ventrals, 

 58 to 75 across the middle of the body. Ventral plates in 10, rarely 

 1'2, regular longitudinal and 27 to 34 transverse series; the plate-> of 

 the median serit^s longer than l)road, the others a little broader than 

 long. Preanal region covered with small irregular plates.
