the nasal shield, which is followed by a quadrangular frenal, 

 placed obliquely over a triangular praeocular. Internasal 

 broad, longer than frontal ; no fronto-nasals ; a pair of fronto- 

 parietals, each as long as the frontal ; two large parietals, one 

 interparietal, and three small occipitals. Three pairs of post- 

 mentals in contact behind the single submental ; large scutes 

 in two series before the collar. Dorsal scales in 35 trans- 

 verse rows from occiput to base of tail, quadrangular, elon- 

 gate, smooth. Sides with much smaller scales, almost granular 

 on the sides of the neck and behind the axilla. Belly with 

 nearly square quadrangular plates, in 10 longitudinal series. 

 Prseanal scutes large, 2, 5, the central one in the hinder row 

 very narrow. The fore limb reaches forward to the eye ; the 

 posterior, half the length of the side. 



Bluish above, with black dots placed irregularly ; a black 

 lateral stripe from the eye along the side of the body. Lower 

 surface paler bluish ; round black dots numerous and distinct 

 on inferior surface of the limbs. 



The specimen in the British Museum is from Guayaquil, and 

 was collected by Mr. Fraser, together with a number of other 

 Cercosaurida3 which have been described from time to time. 



This species differs from E. maculatus, Tschudi, in the 

 absence of fronto-nasals. It appears to resemble considerably 

 Proctoporus pachyurus, Tschudi, but has not the small rounded 

 convex scales on the neck of that species, in which also the 

 number of dorsal rows of scales is 54.

Head rather long and narrow. Ear distinct. Internasal 

 and frontal plates equal, the suture between them straight ; no 

 fronto-nasals ; a pair of fronto-parietals, nearly as long as the 

 frontal, in contact throughout their length; interparietal large, 

 broad ; parietals large, pentagonal ; two postparietals. Nos- 

 tril in middle of a large nasal plate, which is followed by a 

 quadrangular f renal. An elongate plate at the angle of the 

 mouth, and five supralabials ; temporals large, polygonal. 

 Submental elongate, followed by only two pairs of contiguous 

 postmentals ; a third pair are widely separated by a group of
