In this apparently well marked species, there are nineteen rows of dor- 

 sal scales, on the second and third of which are the lateral stripes. The 

 body is rather slender, and the tail more than a fourth of the total length. 

 The color above is olive-brown ; the bands are greenish-yellow, and on the 

 stretched skin red spots show among the black ones, which occur along the 

 sides. 



In their aquatic habits, these snakes differ from E. cyrtopsis and macro- 

 stemma, neither of which, according to my observations, are specially addicted 

 to the water, frequenting dry herbage and bushes like E. sirtalis of the 

 East. I found E. ornata, in June, 1864, in considerable numbers, basking 

 about small, shallow pools in the bosque of cottonwood which fringes the 

 Rio Grande at Los Pinos, N. Mex. No specimens are contained in my col- 

 lections from Arizona itself, where the aquatic species, observed at various 

 points, is E. vagrans.

Form very slender; but little stouter than that of E. saurita; but with 

 shorter tail, one-fourth the total length. Head and eye large. Superior labi- 

 als eight, the sixth and seventh largest. Postorbitals three ; upper much the 

 largest, Dorsal scales in nineteen rows ; lateral stripe on the second and 

 third rows. Olive-brown, with two alternating series of elongated spots 

 between the stripes, giving the appearance of a zigzag line. Dorsal stripe 

 narrow, distinct to the end of the tail, whitish ; lateral stripe like the dorsal 

 in color, broad, distinct from head to arms. A series of black spots on the 

 first dorsal row. Abdomen uniform greenish- white. Orbits whitish. Occip- 

 ital spots obsolete. (KennicoU.*)
