Head and body mod^erately depressed. Head 1^ to H times as 

 long as broad, its length 3^ to 4 times in length to vent in males, 

 4 to 4^ times in females, its depth equal to the distance between the 

 anterior corner of the eye and the tympanum ; snout pointed, as long 

 as the postocular part of the head ; nasals feebly swollen ; canthus 

 sharp, loreal region feebly concave ; a shallow frontal concavity, 

 extending to the middle or the posterior extremity of the frontal shield. 

 Pileus IJ to 2 times as long as broad. Neck as broad as the head or 

 a little constricted. Hind limb reaching the eye or between the ear and 

 the eye in males, the ear or between the ear and the eye, rarely the eye, 

 in females ; foot If to If times the length of the head ; toes slender, 

 feebly compressed. Tail 2 to 2^ times as long as head and body. 



Upper head-shields flat, smooth. Nasals in contact behind the 

 rostral,* the suture between them ^ to ^ the length of the frontonasal, 

 which is as long as broad or broader than long ; prefrontals as long 

 as broad or a little longer, forming a median suture ; frontal as long 

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

 times as long as l>i'oad, separated from tlie supraoculars by a series of 

 small scales ; parietals as long as broad or broader, not longer than 

 the frontoparietals ; interparietal much smaller than the fronto- 

 parietals ; occipital small or minute, often separated from the 

 interparietal by a small shield, sometimes absent. Two large 

 supraoculars, the first sepai'ated from the anterior loreal by one to 

 four series of small scales or granules, the space filled by them equal 

 to or a little shorter than the distance between the two shields ; small 

 granular scales behind the second supraocular ; 5 to 7 superciliaries, 

 first longest ; a series of small scales between the supraoculars and the 

 superciliaries, or one series in front and two behind, rarely two 

 throughout. Three nasals, posterior smallest, loAver in contact Avith 

 the rostral and the first upper labialf ; anterior loreal as long as deep 

 or deeper, shorter than the second, or, rarely, longer than deep and as 



* 111 a female from Ponang Kuma, Mossamedes, the rostral is produced above 

 and separates the nasals. The same specimen is anomalous in havin'j;- the 

 frontonasal and prefrontals broken up into 10 shields. 



t In the type of E. dorsalis and in a male from Lower Nosob (Kimberley 

 Museum), the lower nasal on the left side is in contact with the first and 

 second labiak ; the same exception, on both sides, in a female from Ky Ky.
