LYMN^EHXE OF NORTH AMERICA.

TYPE LOCALITY : Twelve miles west of Cleveland, Ohio. 



ANIMAL, JAW, RADULA and GENITALIA : Unknown. 



RANGE (figure 23) : Central New York to Minnesota, south to 

 Tennessee. Sterkii is typically a species of the Carolinian division of 

 the Upper Austral life zone, extending northward in Minnesota and 

 New York into the Alleghanian division of the Transition zone. This 

 range may be greatly extended when the species becomes well known 

 and special search is carried on for it. Thus far it has been seen only 

 from Illinois, Minnesota, New York, Ohio and Tennessee, and appears, 

 therefore, to be characteristic of the Upper Mississippian, Hudsonian 

 and Canadian regions.
