specimens of Eutaenia sir talis agreeing with several of the 

 subspecin'c descriptions, or differing from all of them. 



20a Eutaenia sirtalis graminea (Cope) 

 Green garter snake 

 Above, light green, with no stripes or spots on upper side of body 

 or head ; below yellow, clouded with green. Lips, chin and throat 

 uniform yellow. 



Cope (1900, p. 1067) lists specimens from Ohio, Massachusetts 

 and Maine. I have never seen a New York specimen of Eutaenia. 

 sirtalis approaching the coloration of this form. 



20b Eutaenia sirtalis ordinata (Linn.) 



Spotted garter snake 

 Jordan. Tharnnophis sirtalis ordinatus 



General color greenish brown or olive ; stripes faint ; three series, 

 of small square dark blotches on each side ; beneath, greenish white, 

 with spots of black near each end of the gastrosteges ; upper labial 

 plates all edged prominently with black. 



I have found this "subspecies" at Yernon, Oneida co., Peekskill, 

 Westchester co., Central Yalley, Orange co. A specimen is in the 

 museum collection, taken by Dr M. S. Farr at Kenwood, Albany 

 co., and another, less typical, taken by Dr Tarleton Bean at Pat- 

 chogue, Long Island. Ditmars ('96, p. 20) mentions specimens taken 

 on Long Island, and at Fort Lee IS". J.; while Wallace (1901) 

 notes the occurrence of the subspecies in Rockland county. 



20c Eutaenia sirtalis sirtalis (Linn.) 

 Striped garter snake
