(Type, Cat. No. 3133.) The character of the cephalic plates appears 

 to be essentially the same as in E. quinquelineatus. The limbs are short ; 

 the hinder applied forward reach just three times to the tip of nose. The 

 fore legs reach forward to the angle of the mouth. The hind leg from 

 knee is about one and one-fifth the head to ear, which is contained five 

 times in the head and body, the hind leg from knee, four and one third 

 times. The neck is thick; the width of head three-fourths the length. 

 The toes are short and thick, the fifth hinder decidedly less than the 

 second, instead of longer, as in quinquelineaUis. The toes are all short; 

 the free portion of longest less than half the head to ear; the fifth less 

 than second. Claws long, acute. There are twenty-six rows of scales 

 around the body, and fifty-nine from occiput to tail. 



Adult light yellowish or reddish blue, each scale with a dusky border, 

 greenish white beneath. Head with a reddish tinge. Young black, 

 the tip and sides of chin white; the labials spotted with white. Five 

 very faint whitish lines; the upper lateral on adjacent edge of scales; 

 the lower distinct only on side of neck. Faint spots on side of neck, 

 cephalic plates above not spotted. 



This species appears to be characterized among its immediate allies 

 by the shortness of the hind toes, the fifth hind toe conspicuously 

 shorter than the second. The description given above is from the type 

 (Cat. No. 3133), which is an old individual.
