the head ; fourth toe, from the base of the fifth, as long as the head 

 or a little louger. Tail 14^ to 1^ times as loug as head and body. 



Upper head-shields convex. Suture between the uasals -J to f the 

 length of the frontonasal, which is broader than long, and a little 

 broader than the iuteruarial space ; prefrontals as loug as broad or a 

 little louger than broad, and forming a median suture ; frontal as long 

 as or shorter than its distance from the end of the snout. If to 2 times 

 as long as broad, rounded or truncate in front, narrow behind ; 

 parietals as loug as Ijroad, outer border straight or concave. Two 

 large supraoculars, preceded and followed by small shields* and 

 granules as in ^. vulciaris and bordered on the outer side by one or two 

 series of granules ; the anterior supraocular as long as or a little 

 longer than its distance from the second loreal : 6 or 7 superciliaries, 

 first longest. Autericjr loreal much shorter than second ; 4 upper 

 labialst anterior to the subocular, fourth longest ; subocular sharply 

 keeled lielow the eye, entering the oral border, often rather largely. 

 Iietween the fourth and fifth upper labials. A large, keeled upper 

 temporal, usually followed liya smaller one; temporal scales granular, 

 convex, upper minute, lower much larger; tympanic shield usually 

 present ; auricular deuticulation absent or very slightly indicated. 



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

 19 to '2ti gular scales iu a straight line between the symphysis of the 

 chin-shields and the median collar-plate, juxtaposed in front, enlarged 

 and imliricate towards the collar ; gular fold absent. Collar free or 

 attached iu the middle, curved or angular, composed of 7 to 11 plates. 



Scales granular on the nape and sides, larger and fiat, round and 

 juxtaposed or subimbricate on the back, largest and often pointed 

 towards the veiitrals, all perfectly smooth ; 58 to 65 scales across the 

 middle of the body. Ventral plates iu regular longitudinal and 

 transverse series, all except the outermost much broader than long, the 

 largest fully twice as broad as loug, iu 10 longitudinal and 26 to 33 

 transverse series. 3 to 5 transversely enlarged preanal plates iu ;i 

 median series. 



18 to 24 femoral pores on each side, the two series meeting or very 

 narrowly separated in the middle. Digits with 3 series of scales, very 

 feebly denticulate on each side ; 19 to 22 tricarinate lamellae under 

 the fourth toe. 



Posterior caudal scales feebly keeled, obli(jue and louger than liroad, 

 the basals perfectly smooth and as loug as broad ; 28 to 38 scales iu 

 the fourth or fifth whorl.
