REPORT OF THE CONSERVATOR OF THE CONCHO- 



LOGICAL SECTION. 



Since the last annual meeting of the Conchological Section, 

 specimens have been received from thirty persons ; the entire num- 

 ber of trays added to the museum being 1,150, a detailed list of 

 which is hereto appended. 



A valuable accession to the museum during the year is the col- 

 lection of mollusks both dry and alcoholic, dredged in Greenland 

 waters, by Professor Angelo Heilprin, of the Peary Relief Expedi- 

 tion. Although they have not yet been studied, the writer has 

 ascertained the presence of a number of species not before in the 

 collection of the Academy, of the genera Margarita, Buccinum, 

 Sipho and other Arctic groups. The specimens being preserved in 

 alcohol, are in excellent condition for the examination of the soft 

 parts. 



Various correspondents of the Conservator have supplied a con- 

 siderable number of our desiderata in United States mollusks ; but 

 the greater number of additions from this country have been through 

 the American Association of Conchologists. The special exhibit of 

 American mollusks, being formed by this Association, has been 

 increased during the year by 443 trays, representing nearly that 

 number of species. The total number of trays now in this American 

 exhibit is 1,510, representing 730 recent and 425 fossil species. 



From Messrs G. E. and A. H. Verrill, we have received several 

 rare species from Dominica, W. I., and from Professor Jose N.
