66 REPORT OF NATIONAL MUSEUM, 1922. 



Dr. J. M. Aldrich, associate curator of insects, has completed a 

 classification of the neotropical genus MesetnhrineUa, a group of 

 large flies that seem to take the place of the blowflies in the tropical 

 parts of the New World. In collaboration with Eay T. Webber, of 

 the Bureau of Entomology, he has almost completed an extensive 

 paper on the Tachinid genus Phorocera and its allies. He has also 

 completed several minor papers, part of them now published. The 

 scientific activities of the honorary custodians of the various sections 

 will appear from the appended bibliography. 



Dr. Mary J. Rathbun, honorary associate in zoology, has prepared 

 manuscripts for the following reports: On the Brachyura collected 

 by Dr. E. Mjoberg's Swedish Scientific Expeditions to Australia, 

 1910-1913, which will form one of the series published in the Kungliga 

 Svenska Vetenskapsakademiens Handlingar; on the Brachyura col- 

 lected by Dr. C. J. van der Horst in Curacao, to be published by the 

 Zoological Society at Amsterdam; on the Brachyura collected in 

 1911 on a cruise to Lower California by the United States Bureau of 

 Fisheries steamer Albatross in collaboration with the American Mu- 

 seum of Natural History, to be published by the American Museum. 

 Of her contemplated series of monographs on American crabs she 

 has nearly completed a second volume on American spider crabs. 

 The first monograph of the series dealt with " The grapsoid crabs 

 of America," and was issued as Bulletin 97, United States National 

 Museum, 1917. In addition, Doctor Eathbun has named the crabs 

 received during the year, of which there have been no small number. 

 The papers prepared by Miss Rathbun and published during the year 

 are listed in the accompanying bibliography. Dr. Waldo L. Schmitt, 

 curator of marine invertebrates, has revised the first part of a report 

 on the Macrura and Anomura of the Australian Museum collected 

 by the Endeavour, in the light of certain further and earlier type 

 material later received from the Australian Museum. Work on the 

 Macrura and Anomura of the American Museum Congo Expedition 

 has been carried along, and it is expected that it will be completed 

 during the ensuing year. A bare beginning has been made on the 

 Macrura collected by the Bureau of Fisheries steamer Albatross in 

 1911 in the Gulf of California under the direction of the American 

 Museum of Natural History. C. R. Shoemaker, assistant curator, 

 has in an advanced state of preparation a report on the amphipods of 

 the Cheticamp Expedition in the Gulf of St. Lawrence. Dr. Harriet 

 Richardson Searle has given some time in continuation of her studies 

 on the Isopoda. She is at present preparing a report on the isopods 

 collected by the Albatross in the Gulf of California in 1911, to be 

 published by the American Museum of Natural History. Her report 

 on the terrestrial Isopoda collected in Java by Dr. Edward Jacobson
