Three large conical scales behind these at the hinder angle of the orbit; groups of large conical scales above the temporal region, round the anterior edge of the ear, and in an isolated patch on the side of the neck. Labial shields 12, equal. A crescentic row of about twelve infra-oculars. Scales of the back and sides of the body very small. A median dorsal crest of large conical scales, beginning behind the occiput, and diminishing on the anterior part of the tail; the highest of these scales are much less than the vertical diameter of the ear. A single lateral series of similar but much smaller scales along each side of the body from the shoulder to the fore part of the tail; below this the scales of the side are minute and granular; above it the dorsal scales are minute but in regular rows up to the dorsal crest, pointed and distinctly keeled; scales of sides of gular region strongly keeled; gular region as far as the chest with very convex erect scales closely set; scales of the entire ventral surface, including the chest, strongly keeled, those of the limbs also keeled. Tail compressed, with complete rings of larger scales alternating with spaces in which the scales are very small; a double series of projecting scales above ; all the scales on the inferior surface large and keeled. A single femoral pore on each side. Mottled and variegated with dark brown on a yellowish ground ; brown-tinged on the tail, or greenish, with a brown network on the sides. Gular region blackish or dark blue (in the male). Entire ventral surface yellowish. A n isolated yellow spot on each side of the neck. In young specimens a yellow lateral stripe on the neck. millim.

Besides these, there were already in the British Museum three specimens collected by Mr. Fraser in Western Ecuador, which Dr. Gunther mentioned as E. laticeps, P. Z. S. 1859, p. 407. The species now described approaches E. heterolepis, Bocourt (Ann. Sc. Nat. [5] xix. Art. No. 4, and Miss. Sc. Mex. iii. livr. 4, pi. 20 c fig. 14), but differs from it in the much smaller size of the |
