less effaced, probably by tbe alcohol. The blotches are light hazel, 

 and the interspaces light chocolate. 



Smaller specimens from Georgia differ only in having the blotches 

 dark hazel, lighter centrally. The intervals are ash-gray. 



The young sustain a close resemblance to the species described 

 from Anderson, S. C. The scales are scarcely if at all carinated 

 however ; the dorsal rows two more : the blotches less regularly quad- 

 rate and not elongate posteriorly. The shape of the head and its 

 plates are different. The markings on the head in the latter are 

 reduced to a uniform black band across the postfrontals, passing back 

 through the eye, and ending acutely on the angle of the mouth. The 

 scales also are more carinated.

1. Scot05>liis qtiatlrivittafiis, B. & G. — Shape of head resem- 

 bling most that of S. lastus. Vertical broader anteriorly and more tapering 

 posteriorly. Dorsal rows of scales 27, the five or eight medial rows alone 

 , carinated; the carination obsolete. Greenish yellow, with four longitudinal 



brown bands.

 Chicken Snake, Baktr. Trav. in Carol., Geo. & Florida, 1791, 275. 



Body slender, tail very slender, about the fifth of the total length. 

 Head elliptical, quite detached from the body by a slender neck. 

 Eyes large. Vertical plate pentagonal, slightly concave on the sides, 

 equalling in length the commissure of the occipitals. The lower por- 

 tion of the anterior orbital is narrower than in S. Isetus. Loral tra- 

 pezoidal. Two elongated and small temporal shields. Upper labials 

 8, 7th largest; lower labials 10, 5th largest. Rostral hexagonal. 

 Scales very thin, lozenge-shaped, constituting 27 dorsal rows. Slight 

 traces of carination may be observed on the five or eight medial rows. 

 The outer row is composed of scales as high as long; in the second 

 row they are perceptibly larger than the remaining ones. 



Ground-color above greenish yellow, with four longitudinal brown 

 bands, covering each one entire row of scales and the half of the ad-
