from the west coast of Africa, donated by Chester W. Washburne, 

 New York City. A further addition to the Cretaceous collections 

 consisted of approximately TOO specimens from the Island of Rugen, 

 gift of Ehrhard Voigt, Dessau, Germany, while the Tertiary col- 

 lections were enriched by 500 specimens of Pliocene fossils from 

 Suffolk, England, donated by Prof. P. G. H. Boswell, of Liverpool. 

 Other gifts of foreign material include 150 specimens from Nova 

 Zembla selected from the material secured by the Norwegian expedi- 

 tion of 1921 and described by Secretary Walcott and Doctor Eesser ; 

 a collection of fossil insects from the Tertiary of Argentina, received 

 from George L. Harrington, Buenos Aires; and a small collection 

 of invertebrates from the Tertiary rocks of Sakhalin Island, pre- 

 sented by Prof. T. D. A. Cockerell. 



By bequest of Col. Thomas L. Casey, Washington, the series of 

 Tertiary invertebrates was increased by several thousand specimens 

 from the classic localities at Vicksburg, Jackson, and Claiborne, 

 Miss., including types described by the donor. 



Casts representing 425 type specimens of rare early Paleozoic 

 fossils from North Greenland and Nova Zembla were made in the 

 paleontological laboratory by Dr. C. E. Eesser, through the courtesy 

 of Dr. Lauge Koch and Dr. Olaf Holtedahl. 



The geological and geographical range of the study series was 

 considerably extended through exchanges which included inverte- 

 brates from the Carboniferous, Chalk, and London Clay of England, 

 and the Tertiary of Florida, France, and Nigeria. These were 

 received from the British Museum (Natural History) ; Arthur G. 

 Davis, London; the Royal School of Mines, South Kensington; and 

 the Florida State Geological Survey. 



Purchases comprised 500 specimens of miscellaneous fossils from 

 the Ordovician and Silurian, and 25 echinoderms from the Creta- 

 ceous of Germany. ■^ 



The notable accessions of paleobotanical material are composed 

 entirely of type specimens. The Miocene plants from the Latah 

 formation near Spokane, Wash., described by Dr. F. H. Knowlton, 

 were in part presented by the Spokane Public Museum and in part 

 transferred by the United States Geological Survey, and Prof. 

 E. W. Berry of Johns Hopkins University donated his types of 

 plants from the Pleistocene of Trinidad and the Cretaceous of Henry 

 County, Tenn. 



The most notable accession to the vertebrate collections is the 

 large series of slabs containing tracks of extinct animals collected 

 by C. W. Gilmore, under the auspices of the National Park Service, 

 from the Coconino sandstone of the Hermit Trail, Grand Canyon 

 National Park, Ariz. These tracks are of unusual interest, not only
