Nat. Sci. Phila., VI, August, 1852, p. 12!1; Fort Webster, New Mexico. Body sleuder, very small, much depressed. Tail two and one-fifth times the head and body. Dorsal scales in fourteen longitudinal and fifty-eight oblique series; sixty-two from chin to anus. Tail with 131 whorls. Scales all entirely smooth, or the middle dor- sal rows with a very blunt obsolete carination. Frontal plate rhomboidal; large, sep- arating the internasals from the ]>ostfrontals. Two pairs of internasals and two of postnasals. Supraorbitals in scales of 5 and 3. lliiid leg from knee equal to dis- tance from snout to ear, which is one-fifth the head and body. Ground color light yellow- ish olive; back with ten broad bars (three scales wide) edged behind with black, having a wliitish mar- gin posteriorly. Tail with thirty half rings of the same, changing behind into blotches. Sides with narrow black bars, on a light ground, greenish white, each scale si)Otted with blackish. The frontal plate of this species is smaller than in many others of the section, although it separates the posterior internasals from the postfrontals, the gap between them filled u[) by the upper i)osterior postnasal. It is (piite probable, however, that occasionally the pos- terior internasals and the postfrontals may come into actual contact, as the former are considerably longer than in G. nudficarinatus. I do not perceive any other special p
