. eluding a number of rare East Indian shells, some of them 

 undescribed. 



Paul Terver. One hundred and seventy-six species of Euro- 

 pean land and fresh-water shells. 



Smaller collections have been received from Gabriel Duqu^, 

 E. H. Jenks, Prof. J. Powell, Edw. D. Cope, G. A. Lathrop, 

 Mrs. Lewis, Dr. Jos. Leidy, C. W. Peale, Dr. James Lewis, Dr. 

 Samuel Lewis, A. H. Smith, John Wolf, J. R. Willis, Dr. 

 Harrison Allen and W. L. Mactier. 



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 Pholadidce to the end of the Tellinidce. 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 refer- 

 ence to the list of donations given above. The following collec- 

 tions have been sent in exchange by the Section : One hundred 

 species of American shells to Luigi Benoit, accompanied 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 duplicate Veneridce has been forwarded to Dr. 

 Edw. Romer, to assist him in preparing for the Section a cata- 

 logue and synonymy of the Veneridce^ which work he has kindly 

 undertaken to perform. 



All of which is respectfully submitted. 



Edward J. Nolan, 



Conservator.
