Batr. Kept., 1875, p. 40. Form very slender; head distinct. Muzzle not elongate nor decurved, somewhat flattened; the apex slightly protruding. Eye rather large. Tail a little less than one-third the total length. Eostral plate slightly recurved on the summit of the muz- zle. Internasals wider than long. Frontal at the narrowest part equals one half the width of the supercili- ary. Parietals openly emarginate, truncate behind. Loreal longer than high; postoculars two; temj)orals 2-2-2. Superior labials eight, the fourth and fifth bounding the orbit below; the sixth snbtriangular, the apex sometimes reaching the inferior pre- ocular; the seventh largest. Inferior labials nine, the fifth the largest. Postgeneials a little larger than pregeneials. Scales in fifteen longi- tudinal rows, those on the anterior two-thirds of the body elongate, those following, wider. Baird and Girard give the following scutal formuljB and measure- ments, the latter in inches: California; gastrosteges, 209-{-1; urosteges, 157; total length, 108; tail, 14. I add the following, measurements in millimeters: Provo, Utah; gastrosteges, 207 +1; urosteges, 138; total length, 1100; tail, 337. A longitudinal dorsal band, six and two half-scales wide, olive-brown, each scale with a rather deeper spot in the center; the four and a half scales on each side of this band yellow, each row with a narrow brown stripe through its
