 Ophibolus getulus subsp. boylii, Cope, Check-List, 1875, 37. 



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- 

 itant of the southern portions of the Territory and southward.

Ophibolus pyromelanus, Cope, Proc. Acad. Nat. Sci. Phila,, 1866, 305 (described from 



Nos. 731 and 760 of my collection from Fort Whipple, August, 1861). 

 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 polysonus, splendidus, &c, Postgeneials half tin- 

 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-
