The number of species presented during the year amounts to about 2150, 

 many of them new to the collection, and a yet greater number from localities 

 not heretofore represented. 



The systematic arrangement of the collection has proceeded from the JPho- 

 ladidce to the end of the Tellinidm. The thanks of the Section are due to 

 Messrs. Parker, Roberts, and Hassler, who have devoted a considerable amount 

 of time to this work, and have succeeded in perfecting an arrangement of the 

 specimens which has been much admired for its neatness, as well as for the 

 opportunity it gives the student of studying, without disturbing the shells. 



During the year we have continued to receive collections from many of our 

 foreign correspondents, as will be seen by reference to the list of donations 

 given above. The following collections have been sent in exchange by the 

 Section : One hundred species of American shells to Luigi Benoit, accompa- 

 nied by a list of Sicilian species desired by us ; eighty species to Aug. Brot, 

 and types of Mr. Gabb's new species to H. Crosse. A collection of our dupli- 

 cate Vmeridie has been forwarded to Dr. Edw. Romer, to assist him in pre- 

 paring for the Section a catalogue and synonymy of the Veneridiv, which work 

 he has kindly undertaken to perform. 



All of which is respectfully submitted. 



Edward J. Nolan, Conservator.
