62 REPOET OF NATIONAL MUSEIJM, 1925 



of this group. He also devoted some time to the identification of 

 the Oriental Ichneumonidae received through Dr. C F. Baker. Dr. 

 W. M. Mann received considerable unworked material of Australian 

 ants through Dr. J. Clark, and during the year identified many 

 of these, and restudied much Australian material. The material 

 from Doctor Clark will form the basis of a synoptic paper on 

 Australian ants. 



Dr. Mary J. Rathbun, associate in zoology, in addition to complet- 

 ing a monograph of the fossil decapods of the Pacific slope of North 

 America, saw through the press the second of her monographic trea;^- 

 tises on American crabs, a volume devoted to the so-called spider 

 crabs, printed as United States National Museum Bulletin No. 129. 

 She furthermore determined numerous miscellaneous accessions. Dr. 

 Waldo L. Schmitt published four papers and made investigations on 

 large collections of East Asiatic macrura and stomatopoda, in par- 

 ticular on a valuable collection of Siamese macrura, to be published 

 in connection with Dr. Hugh M. Smith's investigations of Siamese 

 fisheries. Through the Carnegie Institution, of Washington, D. C, 

 he was enabled to spend during the year 10 weeks at the Tortugas 

 laboratory in furtherance of a series- of studies on the crustacean 

 fauna of the region. Clarence E. Shoemaker, assistant curator, in 

 spite of heavy curatorial and routine work completed reports on am- 

 phipods collected by Frits Johansen in Hudson Bay in 1920 and on 

 amphipods secured during the Albatross cruise in the Gulf of Cali- 

 fornia in 1911. Considerable progress was made on reports on am- 

 phipods collected by the Biological Board of Cailada during fisheries 

 research in the Gulf of St. Lawrence in 1917, as well as on those 

 collected by the curator at Tortugas in the sunmier of 1924. The 

 time of the aide, J. O. Maloney, was mostly taken up in cataloguing, 

 and work in the storage room, but he was able to devote some time 

 to much-needed studies in certain groups of isopods in connection 

 with the many demands by the Federal Horticultural Board and 

 others for determinations of these forms. Dr. Harriet Richardson 

 Searle, collaborator, continued studies as time permitted. Dr. Max 

 M. Ellis, collaborator, made progress with his report on the collec- 

 tions of discodrilid worms secured during several transcontinental 

 collecting trips he has undertaken. The second part of the report 

 on the rotifers of Wisconsin, prepared by H. K. Harring, custodian 

 of Rotatoria, with Frank J. Myers, of the American Museum of 

 Natural History, was issued early in the year. The manuscript and 

 illustrations for a third part have been completed and early publi- 

 cation is expected. The authors last summer at the request of Dr. 

 U. Dahlgren, director of the Desert Island biological laboratory.
