Fig. 4. Trunk vertebra of Notophthalmus cf. N. viridescens (Rafinesque) 

 (USNM 404727) from Unit W3. Upper left, ventral; upper right, dorsal; middle 

 left, posterior; middle right, anterior; bottom, lateral. Line equals 2 mm and 

 applies to all drawings. 



Remarks. — Holman (1967) gave vertebral characters that distinguish 

 this species from others in the genus. The Northern Water Snake occurs 

 in the area today and is found in many aquatic situations. Large popu- 

 lations are often to be found where protective shelters occur near aqua-

Storeria sp., Brown Snake or Red-bellied Snake 



Material — Trunk vertebra: USNM 404744,a from Unit W3, SV-1. 



Remarks. — Holman and Winkler (in press) discuss the separation of 

 isolated vertebrae of the closely related genera Storeria and Virginia. 

 We are unable to separate the vertebrae of the two species of Storeria;
