Habit rather slender, body feebly depressed. Head 1| to If times 

 as long as broad, its length 4^ to 4? 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 canthus and feebly concave loreal 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 between the 

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

 foot IJ to If times as long as the head ; fourth toe, from the base of 

 the fifth, a little longer than the head. Tail li 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 broad 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 broad 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. J First 

 and fourth supraoculars entirely brolcen up into a great numlter 

 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 are 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 young specimens there is a single unpaired shield and tlie prefrontals, 

 are in contact beliind it ; there are 3 unpaired shields in one specimen. 



+ Doumergue is mistaken in stating (p. 175) "Cfites lateraux des parietales. 

 droits." They are often strongly concave in the specimens received from him.
