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



I was not able to assist in the work of collecting either in 187V 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- 

 ei-al years had charge of the woi'k upon the fishes, should be j^artic- 

 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 N. 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 Eui-ope, 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 sei-ies of the Crustacea of the coast of Norway, received from
