CAMBARUS UHLERI Faxon. 
Mr. W. P. Hay captured one specimen of this species near Beaufort, N. C., 
Aug. 17, 1912. This specimen, a female, was taken from a hole in the bank of a 
pond on the south side of Adley’s Creek, about fourteen miles north of Beaufort. 
On the other side of the same creek, about a mile away, Mr. Hay collected three 
specimens of C. diogenes (also females) in holes on the edge of aswamp. The 
specimen of C. whleri differs from the type specimens from Maryland but very 
slightly, the rostrum being a trifle more concave above, and the foveola at the 
base of the rostrum rather more pronounced. 
Uhler’s Crayfish has heretofore been known only from the tidewater Ocean 
and Bay counties of eastern Maryland.
