 has been published during the year in the Bulletin of the Museum 

 (Vol. VIII. No. 1, 2 plates). The Report includes descriptions 

 of twenty-eight new genera and one hundred and sixteen new 

 species. The Oxyryncha^ Cancridce, and Portunidce, together 

 with fifty-five other species, have been returned. 



The Crustacea collected by the " Blake " in 1880, belonging 

 to the more northern fauna investigated by the United States 

 Fish Commission, have been assigned to Professor S. I. Smith of 

 New Haven. 



A part of the Cymothoids of the Museum, sent to Copenhagen 

 in January, 1879, at the request of Drs. Schioedte and Meinert, 

 have also been returned. These were used in the preparation of 

 a monograph of the Cymothoids, contributions to which have 

 appeared in the Naturhistorisk Tidsskrift, Ser. III. Vol. XII., 

 Copenhagen. 



An account of the large collection of Crustacean deformities in 

 the Museum has been published by the Museum (Bulletin, Vol.
