134 ORTMANN — AFFINITIES OF CAMBARUS. [April 13, 
Ohio, as first indicated by Osburn and Williamson (6 Ann. Rep. 
Ohio Ac. Sci., 1898, p. 21), in Sandusky, Erie, and Lorain Cos., 
and in Lake Erie. I have seen specimens (Mus. Oberlin) from 
Huron River, Huron, Erie Co., and from Oberlin, Lorain Co. 
(Waterworks Reservoir and Plum Creek). 
Doubtful Records. — Hagen (1870) gives Huntsville, Madison 
Co., northern Alabama. This is possibly not this species, at any rate 
it is ‘not normal’’ (Faxon, 1885, p. 100). The locality is too far 
separated from the rest of the range, to be accepted without hesitation. 
Faxon (1885) gives: New York (L. A. Lee); Laramie, Wyo- 
ming (U.S. Mus.) ; Orizaba, Mexico (U.S. Mus.), and further in 
1898 he adds: small stream flowing into Oneida Lake, N. Y. The 
locality in Wyoming may be correct, but we have to try to connect 
it with the rest of the range, before accepting it. Orizaba, Mexico, 
is no doubt wrong, and I do not hesitate for a moment to drop it. 
Oneida Lake in New York seems very strange, since there are no 
connecting localities with northwestern Ohio. I cannot accept this 
locality unless verified by unequivocal evidence. 
C. palmeri longimanus Fax.

New Locality. — Rockcastle River, Livingston, Rockcastle, Ky.,

son, Ohio Natural., 5, 1905, p. 310.)
