REPORT OF THE CONCHOLOGICAL SECTION. 



The Recorder of the Conchological Section respectfully reports 

 that during the past year, the Academy has, as heretofore, con- 

 tinued to publish such papers upon the subject of the Mollusca 

 as have been approved by its Publication Committee. 



One member and seven correspondents have been elected. 

 We have no deaths to report ; neither has there been any change 

 made in the By-Laws governing the Section. 



From the eighteenth annual report of Mr. Geo. W. Tryon, Jr., 

 Conservator, we find that during the year ending December 1, 

 1884, sixty donations of mollusks and shells have been received 

 from thirty-one persons. The number of trays and labels thus 

 added to the collection is 1126, of specimens 5224 ; larger acces- 

 sions in both cases than for several previous years. The 

 Conchological Museum now contains 42,448 trays and written 

 tablets, with 151,015 specimens. 



The most important accession of the year is a remarkably fine 

 suite of shells, collected last winter by Mr. Henrj' Hemphill, on 

 the West Coast of Florida. Most of the specimens are in much 

 finer condition than those previously in our Museum, from the 

 same region ; manj'^ of them, hitherto known as West Indian, 

 are now first ascertained to inhabit our coast, and not a few are 

 new species. During the last summer, at the instance of Mr 

 Wm. G. Binney, Mr. Hemphill explored the mountains of North 

 Carolina for Helices, collecting a number of rare and fine specimens, 

 of which, by Mr. Binney's generosity, we have obtained a share. 

 This winter Mr. Hemphill is again spending on the Florida 

 Coast, southward of his last year's operations, and arrangements 

 have been made by which we shall receive a series of his 

 collections. 



A very complete suite of the shells of our national capital 

 were presented by Mr. F. Lehnert.
