Head and budv moderately depressed. Head 1", to li times as 

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

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

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

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

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

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

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

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

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

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

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



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

 rostral,* the suture between them ^ to i the leugth of the frontonasal, 

 wdiich is as long as broad or broader than long ; pi-efroutals 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 broad, 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 lai'ge 

 supraoculars, the first separated 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 supraocidar ; 5 to 7 superciliaries, 

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

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

 throughout. Three nasals, posterior smallest, lower in contact with 

 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 



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

 and separates the nasals. The same specimen is anomalous in having 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 labials ; the same exception, on both sides, in a female from Ky Ky.
