Pp. Ch. — Dorsal rows 15 ; tail about one-third of the total length. A broad brown dorsal stripe margined by a darker line. 

 The four outer rows of scales on each side yellow, with a darker line through the centre of each. A dark line along the edge 

 of the abdiMuen, making six dark lines on each side. Beneath yeUowish.

DIADOPHIS PULCHELLUS, Baird & Girard. 



The Western Ring Snake. 



Diadophis pulchcllus, B. & G. Cat. N. Am. Serpents, 1855, p. 115. 



Sh. Cii — Dorsal scales in fifteen rows; occipital rins; broad; colors, (in ale ,) above uniform dark greenish brown, beneath 

 orange with small black spots irregularly scattered both above and below from head to tail, BOmetimea wanting. Color of abdo- 

 men extending on to lateral dorsal scales. 



A living specimen had the following colors: Top of head glossy, of a dark brownish olive 

 with a bluish tinge, several cf the plates being indistinctly spotted with black. Occipital 

 ring deep reddish orange, having a diagonal width of three scales. A band along the back 

 eleven scales wide of a slaty brown, rather pale, and with a slight greenish tinge anteriorly; 

 posteriorly it becomes more bluish, losing its greenish cast and narrowing on the tail from 

 9 to 2 scales in width. Chin, belly, and first two rows of dorsal scales bright, fiery orange. 

 This color deepens posteriorly, becoming more red, the sub-caudal scutella being almost the 

 color of red sealingwax. A row of black sjjots on each side, each spot being on the posterior 

 edge of the first row of dorsal scales. The abdominal scutelUe have two well-marked rows 

 of small black spots besides several other partial or irregular rows. All these spots are found 

 on the posterior edges of the scales. 



The occipital ring is margined posteriorly by a series of black spots, showing an apparent 

 attempt in nature to form a black linear margin. 



This is the only specimen of the genus or the species that I have seen west of the Rocky 

 mountains. The natives do not say that it is abundant, and the white settlers have only 

 occasionally observed it. Fort Dalles, Oregon Territory, May, 1855. — S.
