discovered in any country, which adds an entirely new phase to the 

 series of variations known in the family Viviparidse. The success 

 of these researches is attributable to the excellent facilities placed at 

 our disposal by Mr. Clarence B. Moore. 



Accessions to our series of American shells have been received 

 from Messrs. A. G. Wetherby, E. G. Vanatta, Morris Schiek, H. 

 F. Stupakoif, H. E. Sargent, C. W. Johnson, O. A. Ny lander, S. 

 N. Rhoads, W. J. Raymond, and numerous others, whose names 

 appear in the list of accessions to the museum. A collection of 

 New Jersey shells has been made and presented by Messrs. Witmer 

 Stone, S. and F. H, Brown. It is now arranged in the Pennsyl- 

 vania and New Jersey department of the museum. 



From Prof. H. W. Gwatkin, of Cambridge, England, we have 

 received a large number of mounted radulae of mollusks, in ex- 

 change for material for mounting. 



Mr. H. Suter and Prof F. W. Hutton, of New Zealand, and 

 Mr. C. Hedley, of Sydney, New South Wales, have continued dur- 

 ing the year to send us new and rare forms of antipodal mollusks.' 

 A series of Sandwich Island forms, collected by Dr. B. Sharp, has 

 added sevei-^l rare or new species. 



Except in the proper placing of new material in the cases, and the 



determination of new and old material, but little work has been 



done in the museum during the year; this has been owing partly to 



the pressure of other work, but mainly to the fact that little can be 



done advantageously until more space is allotted to the Conchological 



department. It is believed that this will be accomplished during the 



coming year. 



Respectfully submitted, 



H. A. PiLSBRY, 



Conservator.
