S. I. Smith — Crustaceans of the Atlantic Coast. 
41 
In the vicinity of Noank, Connecticut, it was occasionally found 
dead upon the shores and was several times obtained from “ lobster- 
traps.” 
The largest specimens I have seen are two males, of almost exactly 
the same size, one from Casco Bay, the other from near Noank, Con- 
necticut. The carapax of the specimen from Casco Bay is 9T6 nlm 
long and 144*5 mm broad.

A careful comparison of three of the original specimens of C. liehrin- 
gianus with specimens from our North Atlantic coast, and with 
Kroyer’s figure and description, convinces me that Stimpson’s species 
is perfectly identical with the C. opilio of Greenland. The differ-
