HARRIS : DISTRIBUTION OF KANSAS CRAYFISHES. 7 



none in the river. I have, however, seen the casts of C. virilis, 

 and think it hardly probable that they could have washed in 

 from any of the small tributaries. 



No. 18 was collected in a small stream. 



8. Cambarus rusticus Girard. 

 Reported only from Osage river. 



9. Cambarus pilosus Hay. 



This somewhat questionable species has been reported from 

 two localities comparatively close together in the north -central 

 portion of the state. 



Mr. Sutton informs me that his material (2) was collected 

 in Kelos Fork, a "wet weather" stream of fresh water which 

 Hows into Salt creek, which empties into the Saline river about 

 four or five miles from where the specimens were taken. At 

 the time the material was taken there was no water flowing 

 from the pools into the creek. During the summer of 1901, 

 Mr. Sutton took material from a well about five feet in depth, 

 near the above region. The water from the pools would over- 

 flow into the well when the water was high. 



10. Cambarus neglectus Faxon. 



4. Wildcat creek, about two miles west of Manhattan, Riley 

 county. Collected with the specimens of C. virilis mentioned 

 above. Presented by J. N. Westgate. 



( '. neglectus, so far as reported, is quite closely confined to the 

 Republican river valley. The Republican river drains Chey- 

 enne ( 2) and Decatur ( 3 ) counties. Mill creek (1) , in Wabaun- 

 see county, empties into the Kansas river about fifty miles east 

 of the Republican. Cat creek (4) empties into the Kansas river 

 about twelve miles from the Republican. Tributaries of the 

 Republican approach to within six miles of the upper part of 

 < 'at creek, but I know nothing of the nature of the country sepa- 

 rating these streams. 



With the exception of the Republican river, in Cheyenne 

 county (2), C. virilis has also been taken from all the above lo- 

 calities. 



The Republican river, in Cheyenne county, wherever I have 

 seen it, is a shallow stream, perhaps 50 to 100 feet wide, with a
