92 REPORT OF NATIONAL MUSEUM, 1920. 



Museum (Bulletin 99) based largely on the material collected by 

 the Smithsonian African Expedition under the direction of Col. 

 Theodore Roosevelt, 1909-10, and the Paul J. Rainey African Ex- 

 pedition, 1911-1912. He also made some progress on the Artio- 

 dactyla, but is seriously hampered by the present inconvenient ar- 

 rangement of the specimens on three different floors of the Museum. 

 Dr. O. P. Hay, of the Carnegie Institution of Washington, District 

 of Columbia, has made constant use of the collection in connection 

 with his work on the Pleistocene fauna of North America. Dr. 

 W. W. Graves, of St. Louis, Missouri, spent about a week examining 

 the shoulder blades of the primates and certain other mammals in 

 connection with his study of human scapulae. 



Dr. W. L. Abbott, of Philadelphia, Pennsylvania, associate in 

 zoology, examined the birds of Haiti and Santo Domingo in con- 

 nection with work he had recently done on the island, and with 

 respect to further needs of the Museum. Mr. A. C. Bent, Taunton, 

 Massachusetts, spent three days examining the eggs and terns, and 

 selecting specimens for illustration in the next bulletin on life his- 

 tories of North American birds. Mr. Francis Harper, of the Bio- 

 logical Survey, worked out the identifications of various specimens 

 collected in France, and of diving petrels. Dr. Alexander Wet more, 

 also of the Survey, continued his volunteer work among the skele- 

 tons and alcoholics, particularly the former, and in making special 

 determinations of skeletal material as needed by the Museum. Dr. 

 H. C. Oberholser, of the same survey, continued to determine speci- 

 mens in the Museum collections, both in the North American series 

 and in the Malayan material collected by Dr. W. L. Abbott and 

 others. Mr. W. H. Osgood, Field Museum of Natural History, 

 Chicago, Illinois, was instrumental in furnishing information that 

 led to the recovery of the important type material of birds from the 

 Chicago Academy of Sciences, mentioned above. 



Dr. Thomas Barbour, of the Museum of Comparative Zoology, 

 during several visits examined and identified reptiles and amphibi- 

 ans in connection with his studies of West Indian herpetology. 

 Mr. E. R. Dunn, of the same museum, identified a number of sala- 

 manders during his visits to the Museum, and Mr. G. K. Noble, of 

 the American Museum of Natural History, New York, was likewise 

 helpful in connection with South American amphibians. 



In the division of fishes Mr. Walter Koelz examined the white- 

 fishes in connection with his work for the U. S. Bureau of Fisheries. 

 Doctor Kendall, of the same bureau, examined certain Scorpaenoid 

 fishes of the west coast for the purpose of more certain identification 

 of specimens collected by Doctor Coker in Peru. Dr. Carl H. Eigen- 

 mann, State University of Indiana, determined 47 specimens of fishes 

 collected in South America by Dr. J. N. Rose.
