Genus Diadophis Baird and Girard. 



4. Diadophis pujictatiis (Linnaeus). Ring-necked snake. 



This species is found occasionally in damp or mossy woods. About 

 a dozen specimens of this species are in the Museum collection, com- 

 ing from various points in the county. The writer found ten eggs in 

 a female specimen taken July 9, 1896. The thickness of the shell 

 enveloping these eggs would indicate that the species is oviparous. 

 The ring-necked snake lives under stones and logs, from which hid- 

 ing-places it emerges in the evenings to hunt. The food appears to 

 be insects and worms : one specimen contained eight beetles, another 

 an earth-worm. Length as much as twenty inches. 



Genus Liopeltis Cope. 



5. Liopeltis vernalis (De Kay). Smooth-coated green-snake. 



This species has not yet been taken in Allegheny County, but the 

 writer took a specimen at Stewart Station, P. R. R., on the borders of 

 a small swamp, which is within one hundred yards of the Allegheny 

 County line. In Fayette and Somerset Counties it is not a rare snake, 

 occurring chiefly on the sides and tops of the mountains. The stom- 

 ach of the specimen captured at Stewart Station contained three grass- 

 hoppers. Its length is twelve and one-half inches. 



Genus Cyclophis Giinther. 



6. Cyclophis cestiviis (Linnaeus). Rough-coated green-snake. 



A specimen of this species was captured near Carnegie, June 17, 

 1897. This is the. only record of this species for Allegheny County. 

 This snake frequently climbs on bushes and vines. It is said to eat 

 insects. The form is very slender ; length about two feet.
