Ereniias. 317 



times as long as broad, its length 4 times in length to vent; snout 

 rather long, very obtuse, with the nasals very feebly swollen, with a 

 median concavity above, extending along the frontal shield ; canthus 

 rostralis sharp, loreal region grooved. Pileus twice as long as broad. 

 Neck as broad as the head. Hind limb extending a little beyond the 

 shoulder ; foot a little longer than the head. Tail nearly twice as 

 long as head and body, flattened at the base, slightly compressed 

 posteriorly. 



Upper head-shields smooth ; nasals in contact behind the rostral, 

 the suture between them ^ the length of the frontonasal, which is 

 broader than long ; prefrontals longer than broad, forming a median 

 suture ; frontal a little shorter than its distance from the end of the 

 snout, nearly twice as long as broad, f of its lateral border in contact 

 with the large supraoculars ; parietals scarcely longer than broad ; 

 interparietal smaller than the frontoparietals ; no occipital. Two 

 large supraoculars, followed by a small one, the space between the 

 first and the posterior loreal equal to the length of the former 

 and filled by 8 to 10 small scales ; a series of granules between 

 the supraoculars and the superoiUaries. Eostral twice as broad 

 as deep ; three nasals, the lower extensively in contact with the 

 rostral and resting on the two first upper labials and just touching 

 the third ; anterior loreal nearly as long as deep, shorter than the 

 second; subocular bordering the mouth, between the 5th and 6th 

 or 6th and 7tli upper labials ; temporal scales hexagonal, smooth ; 

 tympanic shield present ; no auricular denticulation. Lower eyelid 

 opaque. 



6 pairs of chin-chields, the 3 anterior in contact in the middle. 

 20 gular scales in a straight line between the symphysis of the chin- 

 shields and the median collar-plate ; gular fold distinct. Collar 

 curved, free, strongly serrated, composed-of 12 plates, 9 of which are 

 large. 



Scales granular, flat, smooth, a little broader than long, smaller on 

 the upper part of the sides, 56 across the middle of the body. 

 Ventral plates mostly as long as broad, in 12 oblique longitudinal and 

 26 transverse series. A rather large preanal plate, surrounded by 

 smaller plates. 



Upper surface of arjn with small smooth scales. Scales on upper 

 surface of tibia similar to dorsals ; lower surface with a single row of 

 very large shields. 21 to 24 femoral pores on each side, the two 

 series very narrowly separated in the middle. 



Upper caudal scales with strong diagonal keels, lower smooth on 

 the base of the tail.
