134 ORTMANN — AFFINITIES < >F 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.
