beginning of 1880, and hence falls within the scope of this record. 
It gives an account of the Crustacea collected by Professor H. E. 
Webster of Union College, in Virginia, North Carolina and 
Florida, together with a revision of the genera of shrimps. 
This paper has been noticed by Professor Smith (29). It may be 
well to say that the genus Azphocaris, which in the article is 
merged with Caulurus, really is distinct, and belongs to the 
Atyide, near Caradina, as an examination of the mandibles has 
shown. 
The four remaining papers to be noticed treat of the grapsoid 
Crustacea. The first (14) is on the Thelphuside, describing 
some new forms and giving notes on the habitats of others. The 
next (15) is a revision of the fiddler crabs of the world, in which 
the known species are reduced to forty-one. A further examina- 
tion of types ard more complete series would probably reduce 
the number still further. Two new species are described. The 
Ocypodz are next treated in the same manner (16), II spe- 
cies (I new) being recognized. The last of the series (17) takes 
up the family Grapsidz, giving descriptions and analytical keys to 
the majority of the forms. The nominal species of Sesarma are 
merely enumerated in alphabetical order, the task of simplifying 
and straightening them out being too much for the writer. Sev- 
eral genera and many species are thrown into synonymy, and the 
geographical distribution of many is greatly extended. Two new 
genera and species are characterized, and, including the Sesarme, 
159 species are enumerated. 
Professor Packard, who has in progress a monograph of the 
North American Phyllopoda, describes (19) Streptocephalus flort- 
danus as new, and gives notes on other Phyllopods. 
Professor Smith, our oldest publishing American carcinologist, 
contributes several short articles which, like all of his papers, add 
greatly to our knowledge of the Crustacea. In the first of these 
articles to be noticed (26), the presence of the destructive Chelura 
terebrans, a wood-eating Crustacean, is recorded on our shores. 
In the next (31) some forms of British Columbia are discussed. 
A single new genus and species of Cumacea, Diastylopsis daw- 
Soni is described, and the notes on the other forms enumerate 
throw much light on our knowledge of the west coast species. 
In his paper on Pinnixa (32), to be referred to again, the New 
England species, two in number, are described. The next paper
