Specimens from Date Creek, fifty miles south of Fort Whipple. This 

 species, originally described from California, has an extensive dispersion in 

 the West as far north as the Yellowstone, 'as I find a specimen in a collec- 

 tion from that region.

Not contained in my collections. It appears to be rather an inhab-

Ophibolus pyromelamis, COPE, Proc. Acad. Nat. Sci. Phila., 1866, 305 (described from 



Nos. 731 and 760 of my collection from Fort Whipple, August, 1864). 

 Ophibolus pyromelas, COPE, Check-List, 1875, 37. 



" Scales in 23 longitudinal rows ; tail five and one-half times in total 

 length. Scuta 224, 1, 66. Fifty to fifty-eight black annuli on an ochra- 

 ceous white ground, on the body ; each anteriorly completely, posteriorly 

 more or less incompletely, split by a vermilion annulus ; all extending with 

 irregularities on the belly. 



" Head quite distinct from body ; muzzle contracted. Frontal plate 

 broad, with prolonged apex ; parietals elongate, emarginate behind ; cepha- 

 lic shields otherwise as in polyzonus, splendidus, &c. Postgeneials half the 

 length of the pregeneials. Dorsal scales rather broad ; outer series not 

 abruptly enlarged. In one specimen, all the black annuli to the middle of the 

 tail are divided by the red, thus leaving the black as a margin to it ; hence 

 the number of these annuli is fewer ; they are four scales wide behind the 

 middle of the body. In another specimen, only four anterior rings are com-
