REPORT OF NATIONAL MUSEUM, 1918. 35 



suited in two papers now in press, one on mammals and reptiles col- 

 lected by Mr. Theodoor de Booy in the Virgin Islands and one in 

 which the alleged human characters of the Piltdown jaw are given 

 detailed analysis. Mr. Ned Hollister, superintendent of the National 

 Zoological Park, completed and submitted for printing the manu- 

 script of Part 2 of the report on African mammals in the National 

 Museum. It includes the rodents, the lagomorphs, and tubulidentates. 

 He has also done some work on the lemurs for Part 3. Dr. C. Hart 

 Merriam, associate in zoology, in continuance of his work, has pub- 

 lished a synopsis of the members of the grizzly and brown bear 

 groups. The zoologists of the Biological Survey have as usual had 

 unrestricted access to the collections, and Dr. O. P. Hay, of the Car- 

 negie Institution of Washington, has made constant use of them in 

 connection with his studies of the North American Pleistocene fauna. 

 Dr. J. L. Wortmann studied the skulls of primates, insectivores, and 

 marsupials, and Dr. Milo Hellman, of New York, examined the skulls 

 of anthropoid apes with reference to the form of their dental arch. 

 During the year he published a paper giving his observations on the 

 orang, primarily based on material in the Museum collected by Dr. 

 W. L. Abbott. Mr. Roy Andrews, of the American Museum of Na- 

 tural History, New York, compared specimens of Chinese mammals 

 with material collected by Mr. Sowerby, and Mr. Leon Augustus 

 Hausman spent several days in going systematically through the 

 collection to obtain samples of hair for microscopic examination. 

 Specimens were lent for study to Mr. CI. Gaillard, director of the 

 Natural History Museum, Lyon, France ; Dr. J. A. Allen, American 

 Museum of Natural History, and Dr. Milo Hellman, New York City ; 

 Mr. Leon Augustus Hausman, Cornell University ; Mr. W. H. Osgood, 

 Field Museum of Natural History, Chicago ; Prof. Frank Blair Han- 

 son, Washington University, St. Louis, Missouri; and Mr. Joseph 

 Grinnell, Museum of Vertebrate Zoology, Berkeley, California. 



Birch. — The birds collected by Mr. H. C. Haven in Celebes con- 

 tinue to occupy the first place among the ornithological accessions. 

 This year the new material comprises 767 skins and 32 skeletons and 

 is of particular interest, because it includes quite a number of 

 species from the higher altitudes, some of them new to the Museum. 

 Among such novelties are at least two new genera, Media and Andro- 

 philus, with another possibly hitherto undescribed genus. The col- 

 lection is also of interest through having been made in the border 

 country between North and South Celebes, the faunas of which 

 differ considerably, though the full significance of the material will 

 not be appreciated until the entire Celebes collection has been care- 

 fully studied. As in former years, Dr. W. L. Abbott's own collec- 

 tions in Haiti have resulted in important additions— namely, 394
