I9 o 5 ]' URTMANN — AFFINITIES OF CAMBARUS. 135 



Wissahickon, Philadelphia Co.; Shoemakersville, Berks Co.; Valley 

 Forge, Chester Co.; Grenoble, Bucks Co.; New Hope, Bucks Co.; 

 West Manayunk, Montgomery Co.; Wallingford, Delaware Co. 

 Other new localities in eastern Pennsylvania are : Headwaters of 

 Loyalsock Creek and Ganoga Lake, Sullivan Co. (Ac. Philad.); 

 Pinegrove, Cumberland Co. (Ac. Philad.). 



Doubtful Record. — Lake Superior, given by Hagen on the au- 

 thority of L. Agassiz, is undoubtedly wrong. As to records of this 

 species from Ohio see C. bartoni robustus. 



C. bartoni robustus ( Hag. ) . 



New Localities. — Small stream tributary to Rockcastle River, 

 Livingston, Rockcastle Co., Ky., coll. by E. B. Williamson, June 

 21, 1904 (Carn. Mus. ) . These specimens agree well with young 

 individuals of this variety ; adult ones are not in the lot. (See 

 Williamson, Ohio Natural., 5, 1905, p. 310.) Oberlin, Lorain 

 Co., Ohio (Mus. Oberlin). This form was doubtfully reported 

 from Knox Co., Ohio, by Osburn and Williamson (1896). All 

 specimens from Oberlin seen by the writer belong to this variety. 

 The typical form seems to prevail in southern Ohio. 



Doubtful Records. — Faxon (1885) gives Decatur, Macon Co., 

 111., but this needs confirmation. Further it is doubtful, whether 

 the form called by this name in Maryland and Virginia is identical 

 with the true (northern) robustus. 



C. bartoni longirostris (Fax.). 



Doubtful Record. — Pollard, Escambia Co., Alabama, seems 

 doubtful, since it is close to the Gulf coast, and far away from the 

 original mountain home of this form. 



C. latiinanus (Lee). 



The locality, Ocean Springs, Miss., is doubtful for the same reason. 



C. carolinus Er. (= dubius Fax.). 



The reported occurrence of this species in Indian Territory 

 (Faxon, 1890) seems strange. It must be looked upon as doubtful 

 till the connection with the rest of the range is established. 



C. diogenes Gir. 



New localities. — Cooper, Greene Co., Iowa, coll. by J. B. 

 Hatcher (Carn. Mus.); Seaford, Sussex Co., Delaware, coll. by S. 

 N. Rhoads, June 18, 1903 (Ac. Philad. and Carn. Mus.). — Ober- 

 lin, Lorain Co., Ohio (Mus. Oberlin). — The specimens from this 

 locality have been mentioned by Osburn and Williamson (1898) 

 as C. dubius ?, but they are typical C. diogenes.
