Habit rather slender, l)ody feebly depressed. Head li to 1;| times 

 as long as broad, its length 4^ to 4i times in length to vent, its depth 

 equal to the distance between the anterior corner or the centre of 

 the eye and the tympanum ; a deep lanceolate concavity from the 

 frontonasal to the middle of the frontal ; snout pointed, as long as 

 or a little longer than the postocular part of the head, with rather 

 sharp cauthus and feebly concave lorea.l region ; nasals feebly swollen. 

 Pileus twice as long as broad. Neck as broad as or a little narrower 

 than the head. The hind limb reaches the collar or lietween the 

 collar and the ear in males, the shoulder or the collar in females ; 

 foot 1 J to 1| times as long as the head ; fourth toe, from the liase of 

 the fifth, a little longer than the head. Tail H to 2 times as long as 

 head and body. 



Upper head-shields convex, rarely slightly rugose in the adult. 

 Suture between the nasals ^ to ^ the length of the frontonasal, which 

 is as long as l)road or a little broader than long, a little broader 

 than the internarial space and frequently divided into two by a 

 median cleft* ; nearly constantly two azygos shields separate the 

 prefrontals, t which are longer than broad ; frontal as long as or a little 

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

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

 parietals as long as ])road or a little longer than broad, often 

 forming a very short suture or separated by a series of granules 

 behind the interparietal, upper border straight or concave. ij: First 

 and fourth supraoculars entirely broken up into a great num))er 

 of granules or of granules and small shields ; second supraocular as 

 long as or slightly shorter than its distance from the second loreal ; 

 2 or 3 series of granules, rarely 1, between the supraoculars and the 

 superciliaries, which arc 6 or 7, rarely 5, in number, the first the 

 longest. Anterior loreal shorter than the second; 4 upper labials 

 anterior to the subocular, which narrowly borders the mouth A large 



* Divided into three in one specimen. 



t In 2 youn<^ specimens tliere is a sinu'le unpaired shield and the prefrontals 

 ar(^ in contact behind it ; there art> 3 uiii)aired sliields in one specimen. 



I Doumergue is mistaken in statinjif (p. 175 1 " Coti's lateraux des parietales 

 droits." They are often stron^-ly concave in the specimens received from liim.
