Crotalus conflucntus, Say, Long’s Exped. II, 1823, 48.—B. & G. Catal. N. Am. Serp. 1853, 8 
Crotalus lecontii, Hallow. Pr. A. N. Sc. VI, 1851, 8. 
Spec Chau. —Plates on crown irregular, angulated, imbricated, and frequently tuberculated, smoother and less elongated 
than in C. atrox. Three, rarely four, rows of scales between the sub-orbital series (which extends to the centre of the orbit) 
and the labials. Labials 14-18 above, 14-18 below. Dorsal rows of scales 25-29. Dorsal blotches brown, margined by narrow 
whitish lines, sub-quadrate, emarginate before and behind; posteriorly intervals greater and spots transversely quadrate, 
ultimately becoming twenty-five to thirty half rings. Colors not deeper posteriorly in old specimens. Two transverse lines on 
superciliary enclosing about one-third, sometimes obsolete. Light stripe from orbit below superciliary to angle of jaw passes 
angle of mouth on the second or third row of scales above the labials. Eostral margined with lighter.—(Kennicott.)

Spec. Char. —Twenty-one to twenty-three dorsal rows of scales all carinated, the two lateral rows but slightly. Greyish ash

Spec. Char. —No loral. Inferior wall of orbit constituted by third labial. Twenty-five dorsal rows. Dark chestnut brown, 
with indistinct vertical dark bars. Line from superciliary along the edge of the head, through the middle of the second supra- 
labial row r . A second line from the lowest point of the orbit parallel to the first.

ochraceous yellow or brown ; lateral greenish white or yellow on the third and fourth lateral rows. Dorsal stripe one and over 
two half scales wide. Lateral row of scales usually the color of the abdomen. Total length about 3£ times that of the tail. 
Dorsal rows 19.—(Kennicott.)
