papers have been published dealing with these various collections, 
and also with certain points in the distribution, coloration, ecology, 
and structure of these animals. In connection with these investiga- 
tions, negotiations have been entered into with the Copenhagen 
Museum, the Bergen Museum, the Berlin Museum, the Indian Museum, 
the Australian Museum, and the Liverpool Museum, and with Prof. 
Déderlein, of Strassburg, and Prof. Koehler, of Lyons, whereby the 
National Museum will receive about 300 specimens, representing 
some 50 species, most of which are new to the collection. 
Dr. Harriet Richardson continued studies on the isopod crustaceans,
