REPORT OF NATIONAL MUSEUM, 1925 65 



of material of the tribe Telamonini. C. Howard Curran, of the 

 Canadian Department of Agriculture, worked material in the 

 Tachinid genera Gonia and Archytas^ and M. C. Van Duzee's revis- 

 ions of the genera Argyva and Syntormon were largely based upon 

 Museum material. James Waterston, of the British Museum, con- 

 tinued cooperation in identifying species of Chalcid flies. Clarence 

 E. Mickel, St. Paul, Minn., has undertaken study of the collec- 

 tion of Oriental wasps of the family Mutillidae. Dr. M. W. Black- 

 man, Syracuse, N. Y., identified all the bark beetles of the sub- 

 family Micracinae, and many species of the genus Pityophthorus,- 

 Dr. J. M. Swaine identified material of the genus Ifs. Dr. T. J. 

 Psota identified many forms in the genus Theodosia, Dr. W. P. 

 Funkhouser studied Membracidae from Mexico and Central America, 

 and Drs. Carl J. Drake, Paul B. Lawson, H. B. Hungerford, and 

 others identified many species in various groups. 



The divison of marine invertebrates, which includes in its collec- 

 tions more phyla than all the other divisions combined, is dependent 

 on outside voluntary assistance more than any other, as the members 

 of the Museum staff have specialized to a great exent in Crustacea. 

 For coelenterates, worms, and sponges especially it is necessary to 

 appeal for outside help. The names of the specialists who have 

 favored us during the present year are as follows : Dr. Henry Bige- 

 low (Medusae, Ctenophora) ; Dr. H. Boschma (Rhizocephalids) ; 

 Dr. L. R. Cary. (Alcyonarians) ; Dr. R. V. Chamberlain (Annelids 

 and Gephyrea) ; Dr. Henri Coutiere (Crangonidae) ; Dr. Joseph A. 

 Cushman (Foraminifera) ; Prof. G. S. Dodds (Fresh-water Ento- 

 mostraca) ; Dr. A. G. Huntsman (Ascidians) ; Frits Johansen 

 (Fresh- water Entomostraca) ; T. Kaburaki (Turbellaria) ; Dr. C. 

 D wight Marsh (Fresh-water Copepods) ; Dr. Maynard M. Metcalf 

 (Salpa, Pyrosoma, Protozoa) ; Dr. J. Percy Moore (Leeches) ; Dr. 

 Charles C. Nutting (Hydroids) ; Dr. Raymond C. Osburn (Bryo- 

 zoa) ; Dr. Henry A. Pilsbry (Barnacles) ; Capt. F. A. Potts (Rhizo- 

 cephalids) ; Prof. Frank Smith (Earthworms, fresh-water sponges) ; 

 Miss Caroline E. Stringer (Turbellaria) ; Dr. W. M. Tattersall 

 (Mysidacea) ; Dr. Aaron L. Treadwell (Annelids) ; Dr. C. B. Wilson 

 (Parasitic and free-swimming marine copepods). 



The curator of mollusks acknowledges the assistance of several of 

 his students at the George Washington University. Mrs. Paul Bow- 

 man assisted in the anatomic study of Cerions and Zonitoides, Miss 

 Harriet Bundick worked on Philippine Epitoniums, Miss Lucy Rear- 

 don on Philippine Acmaeas and Patellas, and Mrs. Mary Gibson on 

 Philippine Neritinas. Several correspondents also have helped with 

 identifications, as follows: Dr. Bryant Walker, Detroit, Mich., 

 speciments from the Alabama drainage; Dr. Frank C. Baker, Uni-
