The character of the accessions to tliis departmeiit duriii;»' the past 

 year is, as usnal, fairly enough iudicated in the list of accessions,* and 

 includes about 75 accession entries. 



As usual, the collecition is indebted -to the U. S. Fish Coinniissiou 

 and its officers for the largest enHcmhlc of donations from a single source. 

 The material received is all from south of Cape Ilatteras, all that from 

 north of this ])oint being retained for study at New Haven, by Prof. 

 A.E. Verrill. This collection, besides the common littoral shells brought 

 back in quantity, contained a fair proportion of deep-water species, ihe 

 study of which is of extraordinary interest. 



Among the named species received during the year and which are of 

 more than ordinary interest may be mentioned a selection of 71 species 

 of shells from Bering Sea, illustrating a recent report by Dr. A. Krause 

 of the exi)edition sent out by the Bremen Geographical Society ; a 

 small series of land and fresh-water shells from Manitoba, illustrating 

 yi paper by the donor, Mr. Kobert Miller Christy, and a very line series of 

 Madagascar land-shells of remarkable character received from Edward
