The lower part of the head and throat is whitish, the belly bluish, Above, olivaceous brown, with two broad bands of black on each side, and perhaps two narrow ones on the back extending from the head to the anterior region of the tail. A whitish or perhaps yellowish stripe extends from the opening of the ear to behind the hind legs, and a similar one from the occiput to the origin of the tail. This species inhabits the same location in Oregon as Elgaria scincicauda. The specimen figured, together with several others, were collected by Rev. George Geary, and sent by him to Dr. Avery J. Skilton, to whom we are indebted for their examination, and to whom we have dedicated it, as a slight acknowledgment of gratitude. Genus CHURCHILLIA, Baird and Girard. GIN. CHAB.- Three pairs of frontal plates; a very small loral, and several postorbitals. Scales earinated. In spite of the great uniformity in the plan of structure of ophidian reptiles, and especially of the genera Coluber and Tropi-donotus, we do not hesitate in separating generically from both of these, the species hereon described. The genus Churchillia has three pairs of frontal plates, one more than in both Coluber and Tropidonotus ; the middle pair, however, is subjected to some irregularities, by which, instead of one pair, there is only an odd plate. In either case it is a constant character proper to our genus. There is a small loral plate and several postorbitals. The scales of the upper part of the body are earinated, as in tropidonotus, but the lateral row, which is contiguous to the ventral shields, is scarcely larger than the other- while in Tropi-donotus, the scales composing that row are much the largest. CHURCHILLIA BELLONA, Baird and Girard. SPEC. OHAB.- Body yellowish, with a series of large subhexagonal patches of brown, bordered with black, and two or three rows of smaller patches on the sides. A brownish black band across the eyes, from top of head to the angle of the mouth. This snake attains a considerable size. The tail, properly so called, is comparatively very short, forming only the ninth part |
