 Red River, near Pembina (?) . The bird, was sick and not able 

 to fly ; so the crayfish were supposed to have been taken in that

 in Souris or Mouse river, in Dakota : "In bed of stream among 

 stones, in shallow water. Very abundant." 



Bundy ('83) says: "One of our most abundant species, fre- 

 quenting running streams." 



Faxon ('90) reports two small specimens of Cambarus, with 

 well-developed eyes, taken, together with C. setosus, by Miss 

 Ruth Hoppin, in Jasper county, Missouri, as probably belonging 

 to this species. 



Hay ('96) reports C. virilis as being confined in Indiana to 

 lakes and streams in the northern part of the state, where it is 

 extremely abundant and attains a large size. 



According to Harris ('00), C. virilis is found principally in 

 running streams, although frequently taken in the same locali- 

 ties as C. immunis. While he never took C. virilis from bur- 

 rows, he has no doubt that the great numbers of burrows which
