Bednagaiii. IH' 



Body iuoderatel\' depressed. Head rather strougly depressed, but 

 occipital region convex, If to If times as long as broad, its depth 

 equal to the distance between the centre of the eye and the tyuipauuni, 

 its length nearly 4-h times in length to vent ; snout obtusely pointed, 

 as long as postocular part of head. Pileus twice as long as broad. 

 Parietal foramen present, but very indistinct. Neck as broad as the 

 head. The hind limb reaches the elbow of the adpressed fore limb or 

 nearly the axil ; foot longer than the head ; digits slender, compressed 

 throughout, somewhat bent at the articulations. Tail nearly 3 times 

 as long as head and body. 



Nostril pierced between four shields : nasals small, forming a very 

 short suture behind the rostral ' ; frontonasal a little broader than long ; 

 prefrontals forming an extensive suture ; frontal 1^ times as long as 

 broad, a little shorter than its distance from the end of the snout, as 

 broad as the sujiraoculars, but slightlv broader in front than behind ; 

 frontoparietals nearly as long as the frontal ; parietals 1 J times as 

 long as liroad, outer border convex ; interparietal scarcely longer than 

 Viroad, or nearly twice as long as broad, as long as or a little longer 

 than the occipital, which is broader, nearly as broad as the frontal. t 

 Four suijraoeulars, first small, second and third equal, fourth small 

 but larger than first and in contact with the upper temjjoral ; 5 or Ci 

 superciliaries, first or second longest ; granular scales between the 

 supraoculars and the superciliaries absent or reduced to two. A 

 single postnasal, forming a suture with the frontonasal ; anterior 

 loreal ^ or f the length of second ; 5 upper labials anterior to the 

 subocular, which is as long beneath as above ; two elongate upper 

 temporals ; temporal scales rather large, subequal, obtusely keeled 



Pterygoid teeth absent. 



Gular scales granular in front, larger and feebly keeled behind, 

 with a median patch of gradually enlarged and imbricate scales in the 

 middle towards the collar ; 24 to 28 scales in a straight line between 

 the symphysis of the chin-shields and the median collar-plate ; no 

 gular fold. Collar very strongly serrated, composed of 8 or 9 rather 

 large plates. 



Scales on najse granular and keeled, on body large, rhombic, imbri- 

 cate and diagonally keeled, passing gradually into the ventral plates ; 

 24 or 25 scales across the middle of the body. J Ventral plates strongly 



* Rostral in contact with the frontonasal in one of the specimens in the 

 American Museum. 



t In the specimen figured by Schmidt the occipital is a little longer than 

 the interparietal and much narrower than tlie frontal.
