the name, callosa, being preoccupied, would have to be 

 changed). 

 Vertigo decora (Gould, Pupa). Columbus, cited by Surface. 

 The place seems to be outside of the range of its distri- 

 bution, and probably pygmcea was mistaken for it, 

 which I received, as "modesta," fromthelate Hy.Moores. 

 fVertigo tridentata Wolf. 



Summit Co.! (Pettingell) ; Cincinnati! (Billups) ; Troy! 

 (Shepherd); Tuscarawas Co., Columbus, Hamilton 

 (St.). Probably all over the state. 

 fVertigo parvula Sterki. X 



Summit Co.! (Pettingell). 

 Vertigo gouldii (Binney, Pupa). 



Summit Co.! (Pettingell); Portage and Tuscarawas Co.s 

 (St.). Probably over the state. 



COCHLICOPID.E 



Cionella lubrica (Muller, Helix), Cochlicopa lubrica, Ferussacia 

 subcylindrica auctt, not Linne. 

 Over the state. 



SUCCINEID.E. 



Succinea ovalis Say, obliqua Say. 



Cincinnati; Medina and Tuscarawas Counties, (rare, St.). 

 Succinea retusa Lea, ovalis Gould. 



Over the state, common and variable. 

 Succinea retusa higginsi Bland. 



Sandusky; Put-in Bay; South Bass Id. (Walker). Seems to 

 be a form of retusa. 

 Succinea aurea Lea. X 



Cincinnati. The Cincinnati conchologists have regarded it 

 as a distinct species; others regard it as a form, or 

 variety of retusa. Not being familiar with it, I am 

 unable to judge on its merits. 

 Succinea avara Say. 



Over the state, common everywhere. 

 Succinea avara vermeta Say. X 

 Tuscarawas Co. (St.). 



It seems that this form is not simply an incidental form of 

 avara, being absent at many places where that sp. is 

 common, but more or less prevalent, or common at 

 some stations, and consequently a variety.
