GERRHONOTUS LIOCEPHALUS INFERNALIS Baird. (ierrhonotrs UocephaltiK infernaUs Baird, Proc. Acad. Nat. Sei. Pbila., 1858, p. 255. Body rather slender, very small, considerably depressed. Tail twice the head and body. Hind leg from knee equal to the head to ear. Dorsal scales in sixteen longitudinal and fifty-one oblique series; sixty- seven from chin to anus; tail with 127 whorls. Eight central or median dorsal rows of scales ob- tusely and faintly cari- nated (very obsoletely on the outer rows); central two or three rows on the tail similar; all the other scales perfectly smooth. Xasal plate applied only against the second labial and separated from the rostral. Three supple- mentary plates between rostral and internasal; the frontal hexagonal en- circled by six plates. Four postnasal, the up per posterior very large and superior. Four lore- als instead of one. Above light olive, with seven or eight obscure bars of darker, bordered before or behind with bars of the ground color, edged faintly with whit- ish. Beneath yellowish, marbled coarsely with olive. Head plain. Tail nearly uniform reddish olive. The single specimen of this subspecies exhibits peculiarities of cephalic plates which, if constant, will at once separate it from all other known North American Gerrhonoti. The head is depressed, running forward to an acute point; pyramidal; the length two-thirds the width, which is five-sevenths the length to ear, which in turn is rather more than one- fifth (about two-ninths) the head and body. The moutli is unusually pointed aud depressed. The dilference in the cephalic plates from those. Please note that these images are
