Hal lit rather slender, body feebly depressed. Head Iri to l^ times 

 as long as broad, its length 4^ to 45 times in length to veut, 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 ; suout pointed, as long as 

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

 sharp canthus aud feebly concave loreaJ region ; nasals feebly swollen. 

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

 than the head. The hind liml) reaches the collar or between the 

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

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

 the fifth, a little longer than the head. Tail li to 2 times as loug as 

 head and body. 



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

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

 is as loug as broad or a little broader than long, a little broader 

 than the iuteruarial space aud frequently divided into two by a 

 median cleft* ; nearly constantly two azygos shields separate the 

 prefrontals,! which are longer than broad ; frontal as loug as or a little 

 shorter than its distance from the end of the snout, 1^ to 2 times 

 as loug as broad, rounded, truncate, or notched iu frout, narrow behind ; 

 parietals as loug a.s broad or a little longer thau 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 broken up into a great number 

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

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

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

 superciliaries, which are 6 or 7, rarely 5, iu number, the first the 

 longest. Anterior loreal shorter thau 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 behind it ; there are 3 unpaired shields in one specimen. 



^ Doumergue is mistaken in stating (p. 17.5) " Cotes lateraux des parietales 

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