7905-] ORTMANN— AFFINITIES OF CAMBARUS. 133 
following localities in this region and the state of Ohio: Water- 
works reservoir, Oberlin, and Plum Creek, Oberlin; further: Ver- 
million River, Beaver Creek, French Creek, all in Lorain Co.; 
Killbuck Creek, Creston, Wayne Co.; Tuscarawas River, Gnaden- 
hutten, Tuscarawas Co. ‘The latter two localities belong to the 
Ohio drainage, while the rest is lake drainage. This variety forms 
a morphological link between C. propinguus typicus and C. obscurus, 
and seems to be intermediate also in its range. 
C. rusticus Gir. 
The locality Lake Superior (L. Agassiz) given by Hagen (1870) 
needs confirmation. As I have shown elsewhere (Ann. Car. Mus., 
V. 3, 1905, p. 387), the locality Pittsburgh is wrong. 
C. neglectus Fax. 
New Locality. — Rogers, Benton Co., Arkansas, coll. by H. A. 
Pilsbry, March 25, 1903 (Acad. Philad. and Carn. Mus. ). 
C. putnami Fax. 
New Locality. — Rockcastle River, Livingston, Rockcastle Co., 
Ky., coll. by E. B. Williamson, June 21, 1904 (Carn. Mus.). 
(See Williamson, Ohio Natural., 5, 1905, p. 311.) 
C. virilis Hag. 
New Locatty. —Sandy Lake, Ontario, Canada, coll. by G. H. 
Clapp (Carn. Mus.). This species has been reported by Ward 
(Bull. Mich. Fish Comm., 6, 1896, p. 15) from Lake Michigan 
and Pine Lake, Charlevoix Co., Mich. 
The locality Lake Superior, given on the authority of L. Agassiz by 
Hagen (1870), has been confirmed by Faxon (1885 ) on the authority 
of C. L. Herrick, and falls within the known range of the species. 
Doubtful Records. — Lake George, N. Y. (L. Agassiz) has been 
recorded by Faxon (1885) with a?. It surely is very doubtful. 
Faxon also mentions this species from Laramie City in Wyoming ; 
this may be correct, but needs confirmation. He records it further 
from near Bridgeport, Jackson Co., in northern Alabama, in the 
Tennessee drainage (U.S. Mus.) ; I seriously doubt the correct 
ness of this locality, since it is the only one east of the line formed 
by the Mississippi and Ohio rivers, and is far remote from the rest 
of the range. 
C. cmmunis Hag. 
New Localttes. —WLamoni, Decatur Co., Iowa, coll. by J. B. 
Hatcher (Carn. Mus.). This species is also found in northern
