CRUSTACEA. 



The following catalogue of the Crustacea has been prepared by Mr. S. 

 I. Smith, excepting the portion relating to the Isopoda, which lias been 

 written by Mr. O. Ilarger.* The list is by no means complete, even for 

 the higher groups which are treated, and no attempt has been made to 

 enumerate the Ostracoids and free-swimming Copepods. Among the 

 Amphipods, the difficult group of Lysianassinse has not been studied, 

 as the species require careful comparison with those of our northern, 

 coast and of Europe. The same is true of the species of Ampclisca, and 

 partially of some other genera. In several cases species are omitted 

 which are as yet only represented in our collections by imperfect, young, 

 or too few specimens. The catalogue is intended, however, to include 

 ivery species which has been mentioned, on good authority, in any pub- 

 lished work as inhabiting the southern coast of New England.

Southern coast of New England to Florida. This species, the largest 

 of our "fiddler-crabs," lives upon salt marshes, usually farther from the 

 sea than the others, and frequently where the water is most of the time 

 nearly fresh.

From Cape Cod to Florida, the Gulf of Mexico, and the West Indies. 

 It makes its burrows only upon salt marshes, but is often seen in great 

 companies wandering out upon muddy or sandy flats, or even upon the 

 beaches of the bays and sounds.

 are taken from Mr. Smith's unpublished manuscript, and his name, therefore, appears 

 as authority in these cases.
