N. HoUister, in making a preliminary examination of the Celebesian 

 mammals collected several years ago by Mr. H. C. Eaven and 

 presented by Dr. W. L. Abbott. Dr. Robert Eidgway, curator of 

 birds, continued liis work on the ninth part of Bulletin 50, The 

 Birds of North and Middle America. The matter relating to the 

 higher groups, including genera of the Falconiformes, with the 

 illustrations, w^as nearly finished. A large number of bibliographic 

 references for the synonymies not only for part 9, but part 10 also, 

 were collected. It is pleasant to be able to report that the manuscript 

 for part 9 of this monumental work is nearing completion. Dr. 

 Charles W. Eichmond, associate curator, owing to the press of the 

 routine curatorial work, found but little time for research. He 

 made some progress, with Mr. B. H. Swales, in their proposed joint 

 work on the birds of the island of Haiti, but not so nmch as they had 

 hoped. Progress was also made on their proposed list of type 

 specimens of birds in the National Museum, as mentioned in last 

 year's report. Mr. J. H. Eiley, aid, continued his studies of the 

 birds of Celebes and also furnished the curator with certain data 

 on generic characters of vultures and hawks. The study of the 

 North American turtles by Leonhard Stejneger progressed but 

 slowly, due to the lack of leisure from routine work. Miss Doris 

 Cochran, aid, besides identifymg the African and Malaysian 

 snakes in the collection, devoted special attention to the reptiles 

 and amphibians of Haiti with a view to a herx3etology of that 

 island. Mr. B. A. Bean, assistant curator of fishes, reports satisfac- 

 tory progress of the report by himself jointly with Dr. Henry W. 

 Fowler, of the Academy of Natural Sciences, Philadelphia, on the 

 fishes of the Wilkes exijloring expedition and other collections. 



Dr. J. M. Aldrich, associate curator of insects, when not occupied 

 with general routine duties, identifications, etc., devoted his time 

 mostly to the study of the muscoid group of Diptera, publishing two 

 short papers and nearly completing several others. Bulletin 116 of 

 the Museum, being a monograph of the dipterous genus Dolichofus, 

 the result of the joint labors of Mr. M. C. Van Duzee, Mr. Frank 

 E. Cole, and himself, was completed and published during the year. 

 The scientific activities of the honorary custodians of the various 

 sections will appear from the appended bibliography. 



Dr. Mary J. Eathbun, honorary associate in zoology, has completed 

 the second paper in the series on crabs obtained by the fisheries inves- 

 tigation ship Endeavour^ 1909-1914; it covers the Brachyrhyncha, 

 Oxystomata, and Dromiacea, and, like the first paper on the Oxyrhyn- 

 cha, will be published by the Commonwealth of Australia. Consid- 

 erable progress has been made on a bulletin on the spider crabs of 

 America. This is the second of her series of valuable monographs, 

 which, when completed, will describe and figure all the species of
