Molhisks. — The most interesting acquisition was the collection of 

 mollusks made by Dr. Paul Bartsch, assistant curator of the divi- 

 sion, on the expedition of the Carnegie Institution to the Bahama 

 Islands. Though not containing a very large number of species, it 

 comprises many thousands of specimens, mainly of land shells, and 

 furnishes important material for the study of variation. Another 

 large collection from the same region, but consisting chiefly of small 

 marine forms assembled by the late Lieut. Madison Rush, United 

 States Navy, was presented by Mrs. John Biddle Porter, of Washing- 

 ton. In the collection of the Rainey expedition to British East 

 Africa were many land and fresh-water shells, of which, it is found, 

 none of the species duplicates any obtained by the Smithsonian 

 African expedition, though the regions traversed were not far apart. 

 A large number of well-preserved specimens of marine mollusks 

 from New England and an exceptionally fine specimen of the rare 

 Murex hednalli from Australia, ail of which were greatly desired 

 for the exhibition series, were donated by Mr. John B. Henderson, jr., 

 of Washington. Mr. Arthur Haycock, of Whitby, Bailey Bay, con- 

 tinued to supply desiderata in the Museum collection of Bermuda 

 shells and also presented a number of types and cotypes of new 

 species from that locality. Of the land shells obtained by the Yale 

 Peruvian expedition and studied and described by the curator of the 

 division, Dr. William H. Dall, a good representation was received as 

 a gift. The Department of Agriculture, through the Bureau of 

 Plant Industry and the Biological Survey, transferred a number of 

 lots of land shells from Porto Rico and Panama, which included 

 several new forms from the latter region. 



The routine work of the division was greatly advanced through 

 the temporary assignment of additional clerical help. Over 3.3,000 

 lots of specimens were labeled, registered, and made ready for incor- 

 poration in the reserve series, and a very large quantity of small 

 material contained in siftings, bottom samples, etc., was roughly 

 sorted preliminary to its study and classification. The entire collec- 

 tion of Naiades, the largest in the world, occupying 514 half-unit 

 trays, was cleaned, revised, and rearranged in accordance with the 

 Synopsis of Mr. Charles T. Simpson, and the trays were so labeled 

 as to furnish better means than heretofore for referring to the
