The specimens thus agree apparently with those mentioned 
by Faxon (189S) from Big Cahawba River, central Alabama, 
(Alabama River drainage), which are said to be intermediate 
tewteen extraneus and girardianus. The typical extraneus is 
reported from Etowah River, Rome, Floyd Co., Ga. (Alabama 
River drainage); the var. girardianus Fax. is known from 
Cypress Creek, Lauderdale Co., Ala., and from Eastanaula Creek,, 
near Athens, McMinn Co., Tenn. (both belonging to the Tennes- 
see River drainage). The new locality belongs to the Cumber- 
land River, and it is remarkable that instead of finding here 
girardianus , we have a transitional form, which rather resembles 
extraneus.
