The transference of this well-distributed species from genus to 
genus is at least some testimony that the genera concerned 
belong to a single family. There is general agreement as to the 
variability of the telson, to which Mr. Vallentin’s collection bears 
further witness.

Among the specimens which I refer to this species, one had 
calceoli on fourteen consecutive joints of the flagellum in one of 
the first antenne, while in the other the calceoli were only on 
alternate joints. In another specimen, calceoli were present on 
alternate joints of both members of the second pair of antenne, 
while on the one remaining member of the first they were, if 
present, very inconspicuous. 
Locality. Low water at top of Roy Cove creek, Aug. 1, 1910.
