CRUSTACEA. 
The following catalogue of the Crustacea has been prepared by Mr. 8. 
I. Smith, excepting the portion relating to the Isopoda, which has been 
written by Mr. O. Harger.* 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 Lysianassinze 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 Ampelisca, 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 
every 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.

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

beaches of the bays and sounds.

are taken from Mr. Smith’s unpublished manuscript, and his name, therefore, appears 
as authority in these cases.
