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 
lai-ger 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 during 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 algae. 
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 
operations 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. For 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. Ilarger and I were present and took part in the work. 
During the last of August and September, a series of dredgings 
were made, on hoard 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 which 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. Ilarger 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 4 I ' 25' to 42' 11', 
and from west longitude 08' 10 to 05° 42'0'; on Le Have Bank, in
