REPORT ON THE CRUSTACEA. 



By Walter Faxon. 



The principal additions to the Crustacea since the last Report 

 consist of a large collection made by the Rev. B. G. Snow at the 

 Marshall Islands, and by the Rev. A. A. Sturgis at Ascension 

 Island ; a lot of forty-three Norwegian species (all identified) 

 from the Bergen Museum ; the dredgings of the United States 

 Coast Survey steamer Blake " in the Gulf Stream (now in 

 the hands of M. Alphonse Milne Edwards, Paris) ; a collection 

 from Professor Lov^n ; and Cladocera from Wisconsin, deter- 

 mined by Mr. E. A. Birge. 



During the winter of 1876-77, I determined and catalogued 

 the large collection of the Cancroids of the Museum, and set 

 apart a series of dry Crustacea to illustrate the fauna of North 

 America. 



During the academic year 1877-78, most of my time has been 

 devoted, as Instructor in Zoology, to the students in that de- 

 partment. Little has been done with the collection of Crustacea, 

 beyond the care necessary for its safe-keeping.
