420 REPORT OF NEW JERSEY STATE MUSEUM. 



In Maryland it is very abundant about most all the Chesa- 

 peake Bay region. I have examined examples at Baltimore in 

 the Patapsco River, the Bohemia River, Cape Charles, Old Point 

 Comfort, and Norfolk, near many of which places are important 

 industries. It is also abundant in the Chincoteague Bay region, 

 as on Chincoteague Island, Assateague, Wallops, and further 

 south as at Cedar Island, Parmores Island and Watchapreague 

 Inlet. Mr. W. T. Davis says this crab is still to be found in num- 

 bers in the salt creeks of Staten Island, N. Y. In winter a great 

 many dead are often w^ashed ashore on the south Side. 



Megalops and Zoea of crabs before me, taken in great abund- 

 ance at Point Pleasant and in Great Egg Harbor, are very likely 

 of this species.
