S. I. Smith — Crustaceans of the Atlantic Coast. 
31 
As in 1873, the steamer Bache continued the dredgings in the Gulf 
of Maine. Professor Packard, assisted by Mr. Cooke and Mr. Robert 
Rathbun, had charge of the work and made large collections between 
Cape Ann and the Isles of Shoals, on Jeffrey’s Ledge, on Cashe’s 
Ledge, and at numerous localities in the deep waters of the Gulf of 
Maine. 
1875. The work under the direction of the Commissioner of Fish- 
eries was in the same region as in 1871, but the dredgings extended 
further to the eastward and included the region east of Nantucket. 
In addition to this, Professor Merrill and Mr. C. Hart Merriam, 
during a short excursion to Barnstable, on the north side of Cape 
Cod, made collections of many of the species inhabiting the shores 
and shallow waters of the southern part of Cape Cod Bay. 
1876. Mr. C. Hart Merriam and Mr. E. B. Wilson made some col- 
lections at Eastport, Maine, in April, and very kindly submitted the 
crustaceans to me. The collection was particularly interesting on 
account of the season at which it was made, all the other collections 
which I have examined from the same region having been made late 
in the summer or early in the autumn. 
1877. The extensive collecting prosecuted under the direction of 
the Commissioner of Fisheries was resumed, the collections of the 
invertebrates being, as before, in charge of Professor Verrill, who 
was this year assisted by Mr. E. B. Wilson. Extensive collections 
were made at Salem, Massachusetts, and in the neighboring waters 
of Massachusetts Bay and the Gulf of Maine. During a part of the 
season the work was transferred to Halifax, Nova Scotia, where large 
collections were made and whence the dredging was extended to the 
deep waters one hundred and twenty miles south of that city. On 
the passage from Salem to Halifax, dredgings were made in the deep 
waters of the Gulf of Maine and off the southern portion of the 
Nova Scotia coast. 
1878. The work in connection with the investigation of the fish- 
eries was continued in the vicinity of Cape Ann, the field investigated 
being contiguous to, and partially overlapping, that in the vicinity of 
Salem in 1877. In addition to the material obtained upon the shores 
and by dredging, valuable collections were procured, at Gloucester, 
Massachusetts, the head-quarters of the Commission for the season, 
from vessels engaged in the bank-fisheries. Professor Verrill was 
specially assisted by Mr. Richard Rathbun and Mr. Sanderson Smith. 
The collections of this year came to hand too late to be used to any 
considerable extent in the present paper, and consequently only occa- 
sional references are made to them.
