pods, and, collaborating- with Dr. Bartsch, a joint report on the mol- 

 lusks of the region about Beaufort, North Carolina. Miss Julia A. 

 Gardner, United States Geological Survey, studied the recent mol- 

 lusks in connection with work on the Alum Bluff formation during 

 the first few months of the year, and Dr. Charles W. Cook, also of the 

 Geological Survey, similarly consulted the collection for the purpose 

 of comparison with the Eocene and Oligocene faunas. 



Other specialists prosecuting investigations, who were given the 

 facilities of the division and the subjects which had their attention, 

 were as follows: Dr. Joseph A. Cushman, of the Boston Society of 

 Natural History, marine deposits for the monograph of the North 

 Atlantic foraminifera ; Prof. C. C. Nutting, of the State University of 

 Iowa, the hydroids for the next part of his monograph, data for 

 trip to the Island of Barbados, and determining material secured 

 during the trip; Dr. Walter K. Fisher, of Leland Stanford Junior 

 University, starfishes of the Albatross Philippine expedition; Dr. 

 Maynard M. Metcalf, of Oberlin College, Salpa and Pyrosoma, and 

 protozoans; Mr. George H. Clapp, of Pittsburgh, American land 

 shells, especially the polygyrids, assisting the Museum in bringing 

 up to date the identifications and nomenclature of the latter; Dr. 

 L. R. Cary, of Princeton, New Jersey, the alcyonarians, aiding the 

 Museum in the preliminary segregation of the group; Mr. Bryant 

 Walker, of Detroit, Michigan, the Unionidae; Miss Ruth Bennett, 

 of George Washington University, the West Indian operculate land

 Hawaii, Mr. Herbert N. Lowe of Long Beach, California, and Mr. 

 William F. Clapp of Cambridge, Massachusetts, mollusks of vari- 

 ous groups. 



The Museum continued with great success and to mutual advan- 

 tage availing itself of the kind assistance of a great number of spe- 

 cialists in various parts of the country and abroad for the purpose 

 of indentification and report upon material in groups not covered 

 by its regular staff of scientific workers. A number of such reports 

 have been received and some of them published during the year, 

 among them Dr. Alfred Goldsborough Mayer's "Report upon the 

 Scyphomedusae collected by the U. S. Bureau of Fisheries steamer 

 Albatross in the Philippine Islands and Malay Archipelago"; Dr. 

 S. S. Berry's "Chitons taken by the U. S. Fisheries steamer Albatross 

 in the Northwest Pacific in 1900"; Prof. G. S. Dodd's "Altitudinal 

 distribution of Entomostraca in Colorado"; Dr. W. G. Van Name's 

 "Ascidians from the Philippines and adjacent waters." In addition
