June, 1901] Griggs — Vernation of Salix 127 



Fam. CoLUBRiD^. 



Carphophiops amoenus (Say.)- This specimen is marked C. helenae 

 Kenn. The internasal scutae are wanting. The specimen is from 

 Meigs Co. Another specimen is in the collection but without label. 



Diadophis punctatus (L. ) Sugar Grove. 



Heterodon platyrhinus Jj?bt. Cedar Point. Both the spotted and 

 the blacli forms occur on Cedar Point. 



Liopeliis vernalis (DeKay.). Sandusky and Columbus, 



Zamenis constrictor (Linn.). Hocking County. 



Coluber vulpinus (B. and G.). The range of the fox snake, as 

 given by Cope (Kept. U. S. Nat. Mus., '98, p. 832) is '' over the north- 

 west of the Eastern district, not being known from east of Illinois***." 

 Specimens are taken from Cedar Point and vicinity nearly every 

 summer. Those in the collection are from Castalia and Cedar Point. 



Coluber obsoletus obsoletus Say. Columbus. 



Osceola doliata triangula (Boie.). Columbus and London. 



Natrix fasciata fasciata (Linn.). Warren County. 



Natrix fasciata sipedon (Linn.). This is the common "water 

 snake" of central Ohio. Specimens are from Sandusky and Columbus. 



Natrix fasciata erythrogaster (Shaw.) Put-in-Bay. Among the 

 islands of Lake Erie this seems to be the prevailing form. One 

 young Natrix was taken during the summer of 1900 which resembled 

 N. f. sipedon L., but aside from this all other forms were erythro- 

 gaster. It may be possible that the young of these two sub-species 

 are not distinquishable — the differences arising later. 



Natrix leberis (Linn.). Columbus and Sandusky. 



Natrix kirtlandii (Kenn.). New London and Sugar Grove. 



Storeria dekayi (Holb.). Columbus. 



Storeria occipitomaculata (Storer). Sugar Grove and Kent.

Eutaenia sirtalis ordinata (Linn.). Columbus. 



Eutaenia sirtalis obscura Cope. Cedar Point and Columbus.
