27. Crayfish are not at all common in the lower part of the Kansas river, at least near Lawrence, where I have had opportunity to observe it. The fishermen, as a rule, say there are 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. Cambaras rusticus Girard.
Reported only from Osage river.
9. Cambaras pilosus Hay.
This somewhat questionable species has been reported from two localities comparatively close together in the north-central portion of the state.
