Academy of Sciences enters upon a new era of activity. Its publica-

Dr. Joseph F. James begs to inform his friends and correspondents 
that he has removed from Washington, D. C., and that after May 10, 
1896, his address will be Hingham, Mass. 
I desire to secure good sets, cleaned or uncleaned, numbering fifteen 
or more specimens each, of your local representatives of Campeloma 
(Melantho of Authors), Lioplax aud Vivipara. Where extra large sets 
can be sent they will be of especial value since the present object is 
monographic. Exchanges are offered in southern Unionide and Stre- 
pomatide. The rarer forms of the last named groups are also desired.
