38a- 



specimens of Eutaenia sirtalis agreeing with several of the- 

 subspecific descriptions, or differing from all of them.

 Green ga/rter 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

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

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