S. I. Smith — Crustaceans of the Atlantic Coast. 123 



anywhere near the south coast of New England or the coast still 

 further south, whether they properly belong to the fauna south of the 

 Cape or are northern species which occur only in exposed situations, 

 in deep water, or in winter; but to distinguish these two classes of 

 species, the northern ones are indicated by an asterisk (*). Under 

 " Massachusetts Bay," two or three rare species taken off Cape Ann, 

 but not as yet actually in the Bay, are included. Under " Nova 

 Scotia," only those species which have been observed on or near the 

 southeast coast are included ; the species of the northern, or Gulf-of- 

 St. Lawrence, coast being included in the eighth column, while a few 

 species taken only in deep water (one hundred or more fathoms) far 

 off the Atlantic coast, are included in the seventh column. Under 

 " Gulf of Maine, etc.," are included the species found in the Gulf of 

 Maine proper (the great region of comparatively deep water, but 

 with numerous banks and " ledges," between St. George's Banks and 

 the shallow waters of the coast from Cape Cod to Nova Scotia), and 

 also the species found on St. George's Banks, LeHave Bank, etc., and 

 the deep waters outside of them. Under " Gulf of St. Lawrence and 

 Labrador," are included the species found in the Gulf and on the east, 

 or Atlantic, coast of Labrador, though in the present list all the spe- 

 cies known from the east coast of Labrador have been found also in 

 the Gulf. A few species whicli have been found in the shallow south- 

 western part, including Northumberland Straits and the Bay of 

 Chaleurs, and not in other parts of the Gulf, are indicated by a dag- 

 ger (f). Under " Bering Sea," species known from any part of the 

 North Pacific or from the Arctic Ocean immediately north of Bering 

 Straits are included. The number of species common to this region 

 and the North Atlantic will undoubtedly be very largely increased 

 by subsequent investigation. 



In checking in the table the occurrence of the species, a mark of 

 affirmation (!) is used, as in the previous pages, when I am myself 

 responsible for the identification of the species; the plus sign (+), 

 when the species has not been seen by me but has been recorded on 

 good authority ; and by a mark of interrogation (?), when there is 

 doubt in regard to the identification of the species. 



In the bathymetrical distribution, under " Fathoms," the depths 

 within which the species have been found upon our coast only are 

 o-iven.
