32 S. I. Smith — Crustaceans of the Atlantic Coast. 
I was not able to assist in the work of collecting either in 1877 or 
1878, but the crustaceans in the collections of these years have nearly 
all been placed in my hands in the original packages in which the 
specimens collected at each special locality were placed, so that I am 
alone responsible for the determination of the species from each of 
these special localities. 
Several gentlemen, in addition to those above mentioned in connec- 
tion with the work of the Fish Commission, aided in collecting during 
different seasons; the gentlemen who were specially engaged in inves- 
tigating the fishes, also, gave every season, more or less assistance in 
collecting the invertebrates. Mr. G. Brown Goode, who has for sev- 
eral years had charge of the work upon the fishes, should be partic- 
ularly mentioned in this connection. 
Mention should also be made of the small collections which have, 
from time to time, been made, in the interest of the United States 
Fish Commission, by Mr. Vinal X. Edwards in the vicinity of Wood’s 
Holl, Massachusetts (Vineyard Sound and Buzzard’s Bay). These 
collections have been made mostly in the winter and spring and for 
this reason have proved of special interest, often containing species 
rarely or never taken in summer, and in several cases materially help- 
ing to complete the annual history of a species. 
For the use of a few specimens of rare species, not fully represented 
in the collections above referred to, and also for the freest access to 
the collections under their charge, I am under obligation to the officers 
of the Boston Society of Natural History, the Peabody Academy of 
Science at Salem, and the Portland Society of Natural History. In 
addition to the use of the collections made under the auspices of the 
United States Fish Commission, I am indebted to Professor Baird for 
the opportunities of examining several collections from our southern 
coast and from Europe, for the loan of books, and for the use of sev- 
eral of the drawings made by Mr. Emerton, which appear in the 
accompanying plates. To Professor Verrill, I am indebted for the 
constant use of the valuable collection of crustaceans, of which I 
formerly had charge, in the Museum of Yale College, as well as for 
his advice and assistance in many ways. The Museum, in addition to 
the collections above referred to, contains large collections made in 
the vicinity of New Haven during many years ; an authentic set from 
the collection which served as a basis for Professor Packard’s work 
upon the invertebrate fauna of Labrador, contained in the first volume 
of the Memoirs of the Boston Society of Natural History; a very 
valuable series of the Crustacea of the coast of Norway, received from
