Descviftion. — This is the best known form of the genus, and the 

 one of which the most specimens have been available for study. The 

 following summary of the scutellation is based upon the examination 

 of about 400 specimens: Ventrals, 180 to 213; caudals, 29 to 54 

 (males average about 47 and females about 44); supralabials 7, 

 rarely 8; infralabials 9, occasionally 8, less often 10, very rarely 11; 

 1, very rarely 2, preoculars; 2, rarely 1, postoculars; temporals com- 

 monly 2 + 3 + 4, often some lower combination, as 2 + 3 + 3, 2 + 2 + 3, 

 1 + 2 + 3 : posterior chin shields usually shorter than anterior, in 

 contact with each other or separated by 1 or 2 small scales; loreal 

 distinctly longer than high, rarely absent; scale rows on middle of 

 body usually 21, occasionally 23, rarely only 19 (the formula is most 

 commonly 21-19-17 or 19-21-19-17, often 21-19, sometimes 

 21-23-21-19, rarely 19-17). 



This snake is of moderate size. An adult is commonly 2\ to 3 

 feet long. The largest specimen examined was 1,085 mm, in length, 

 and was taken at Cold Spring, New York. Proportions: Head but 

 slightly distinct from the neck, tapering from the temples forward, 

 and truncate at the end; bod}^, rather slender, tapering slightly to- 

 ward the neck and toward the tail, cylindiical above or very slightly 

 compressed; belly flat, and meeting the sides at right angles; tail
