blackish spots. The scales have a ridge or small keel along their mid- 

 dle, and are arranged in 19 or 21 longitudinal rows. The postabdom- 

 inal or anal scutella is entire, like the others. There is one anterior 

 orbital plate and three posterior. The body is either moderately stout 

 or else slender, according to the species. Of the two described in this 

 article, one belongs to the division with a slender body and 19 dorsal 

 rows of scales, and the other to the second division, with a stouter body 

 and 21 dorsal rows of scales.

 Zoology, PI. II. 



Spec. char. — Body stoutest of the division. Black above ; three 

 longitudinal stripes, the dorsal ochraceous yellow or brown, lateral 

 greenish white or yellow. Total length about three and a half times 

 that of the tail. 



Syh. — Coluber proximus, Say, in Long's Expd. to Eock. Mts. I,

Desc. — Deep brown, almost black, above and on the sides ; beneath 

 greenish white. Dorsal stripe on one and two half rows of scales, 

 ochraceous yellow, lateral stripe on the 3d and 4th rows of scales, green- 

 ish yellow or white, markedly different in tint from the dorsal. Sides of 

 abdominal scutellse, and 1st and 2d dorsal series, of the same color as 

 the back. On stretching the skin, numerous short white lines are visible. 

 Occipital plates with two small approximated spots on the line of junc- 

 tion. Orbitals whitish. The greenish white of the abdomen becomes 

 more yellow anteriorly. " 



Head more like that of E. saurita than of E. Eaireyi, while the 

 body is stouter than in either. The subcaudal scales are less numerous 

 than in the other two allied species. Eesembling E. Faireyi in color, 

 it is always distinguishable by the stouter body, fewer caudal scales, 

 and dissimilarity of color in the longitudinal stripes. 



Dorsal rows of scales 19, all keeled; abdominal scutellse 170; sub- 

 caudal ones 100. Total length 33 inches; length of tail 9 inches. 

 Found at Camp No. 7. 



The species is represented in natural size on Plate II.
