Lamprosoma episcojmm Kenxicott, U. S. Mex. Bound. Surv., II, Reptiles, 1859, p. 22, pi. VIII, fig. 2. Homalosoma ejnscopum Jan, Icon. G6n. Opbid., Pt. 13, pi. iv, fig. 2. Form rather stout, tapering very little toward the neck, which is not niucli narrower than the head, and moderately tapering toward the tail. The tail forms about one-fifth of the total length. Head rather depressed; crown flattened iwsteriorly. Snout broad, rounded, and depressed. Frontal a third longer than wide; scarcely tapering behind; acute posteriorly, and usually slightly concave on the sides. Suporcil- iaries and parietals short and narrow. iTasal elongated; nostril very small in the center of the plate. Loreal elongated; not half as large as the anteorbital, which is itself small and vertically elon- gated. Postorbitals of nearly equal size. Temporals, 1-2. Ros- tral subpentagonal; the npex acute and turned back upon tlie crown, entering slightly between the prefrontals. Seven upper labials; fourth, fifth, and sixth largest and nearly equal in size, seventh very small. Lower labials seven; the fourth very much the largest. The dorsal scales in fifteen rows; they increase regularly in size from the central rows, which are much the smallest, to the first lateral row, which is higher than long. The color of the entire upper parts of head and body is uniform light olive brown tinged with green, but on close inspection each scale is seen to be very minutely mottled with black toward the center, and upon stretching the skin the base of each scale is black. A rose-colored vertebral stripe in life. The abdomen is uniform whitish green. In a specimen from Eio Seco the exposed base of each scal
