S. J. Smith — Crustaceans of the Atlantic Coast. 29 



Harbor, New Jersey; a special object of the excursion being the 

 determination of the species described from that region by Say. 



The systematic exploration of the waters of our coast were this 

 year begun, in connection with the investigations concerning the 

 coast fisheries, under the direction of Professor Baird, United States 

 Commissioner of Fish and Fisheries. Under these auspices, the 

 larger part of the collections referred to in this paper have been 

 made. In 1871, this work was carried on in the region of Vineyard 

 Sound and Buzzard's Bay, from late in June to the middle of Sep- 

 tember. The dredging operations and the care of the collections of 

 invertebrates were in my charge dui'ing the first part of the season, 

 later in care of Prof. J. E. Todd, and finally under the direction of 

 Professor Verrill, more or less assisted by Professors A. Hyatt and 

 A. S. Packard, Jr., and particularly by Prof. W. G. Farlow, who 

 was specially engaged in collecting and studying the algre. 



1872. Under the auspices of the Commissioner of Fisheries, large 

 collections were made, during July and August, at Eastport, Maine, 

 and in the whole neighboring region of the Bay of Fundy. As in 

 the succeeding years. Professor Verrill had charge of the dredging 

 opei'ations and the collections of invertebrates. For a large part of 

 the season Dr. T. M. Prudden cared for the crustaceans and made 

 valuable notes on the stations and color of the species. P^'or a part 

 •of the season Prof. H. E. Webster was at the island of Grand 

 Menan where he made valuable additions to the collection of crus- 

 taceans, particularly among the species of Hippolyte. Several other 

 gentlemen aided in the general work of collecting, and, for a time in 

 August, Mr. Harger and I were present and took part in the work. 



During the last of August and September, a series of dredgings 

 were made, on board the Coast Survey steamer Bache, in the region 

 of St. George's Banks and the adjacent waters. An account of these 

 dredgings has already appeared in the third volume of these Trans- 

 actions. This, the earliest exploration with the dredge, of the region 

 referred to, was carried out through the cooperation of Professor 

 Baird and the Superintendent of the Coast Survey. During the first 

 cruise, on Avhich dredgings were made on, and east of, St. George's 

 Banks ; at Halifax, Nova Scotia; and on Le Have Bank, the dredg- 

 ing was in charge of Mr. Harger and the writer. On the second 

 cruise, dredgings were made by Prof. A. S. Packard, Jr., and Mr. 

 Caleb Cooke, in the region of St. George's Banks. In the latter 

 region the dredgings extend from north latitude 41° 25' to 42° 11' 

 and from west longitude 68° 10' to 65° 42-3'; on Le Have Bank, in
