18 ANNUAL REPORT SMITHSONIAN INSTITUTION, 195 3 



fossils from Iowa, Tertiary invertebrates from Trinidad, and Foram- 

 inif era from the Gulf of Mexico. 



Through funds provided by the Springer bequest, the Museum ac- 

 quired 11 type specimens of Carboniferous and Ordovician crinoids 

 and 45 metatypes of other Ordovician crinoids from Oklahoma. The 

 Museum purchased under the Walcott bequest Mesozoic invertebrates 

 from the Austrian Alps and Tertiary and Mesozoic brachiopods from 

 Sicily. Fieldwork financed by the same bequest resulted in the col- 

 lection in Mexico of 900 rock samples containing Foraminif era by Dr. 

 A. R. Loeblich, Jr., and Dr. David H. Dunkle, and 10,000 invertebrates 

 by Dr. G. A. Cooper, Arthur L. Bowsher, and William T. Allen in 

 New Mexico, Texas, and Missouri. 



Six transfers were received from the United States Geological Sur- 

 vey, among which were specimens sorted out from the deep-sea cores 

 obtained in the North Atlantic. Another transfer, received from the 

 Office of Naval Research, contains the type specimens of fossil woods 

 from the Cretaceous of Alaska described by Dr. C. A. Arnold, of the 

 University of Michigan. 



One of the largest accessions, 500,000 Arctic Foraminifera, includes 

 materials obtained during cruises of the U. S. S. Albatross vessels 

 under the command of Capt. R. A. Bartlett and Comdr. David C. 

 Nutt, and specimens obtained by Dr. A. R. Loeblich, Jr., under a grant 

 from the Office of Naval Research. 



New and interesting specimens have been acquired by exchange, in- 

 cluding many genera and species of Foraminifera not hitherto repre- 

 sented in the collections, 158 invertebrates from the Triassic of Eng- 

 land and the Tertiary of Germany, 355 Austrian Triassic brachiopods 

 from the Naturhistorisches Museum, and 69 Paleozoic and Cenozoic 

 brachiopods from Japan from the National University, Yokohama. 



Transfers from the Smithsonian River Basin Surveys include, 

 among others, a nearly complete skeleton of the fossil reptile Gharaf- 

 sosaurus from the Paleocene of North Dakota, a plesiosaur skeleton 

 from the Upper Cretaceous of Wyoming, and some 70 specimens of 

 mammals from Oligocene and Miocene strata of the Canyon Ferry 

 Reservoir area in Montana, all collected by Dr. T. E. White. An im- 

 portant assemblage of Paleocene mammalian jaws and teeth from the 

 Bison basin in central Wyoming as well as several small collections 

 of mammals from Eocene beds of the Powder River and Wind River 

 basins in Wyoming and from the Eocene and Oligocene in Montana 

 were transferred by the United States Geological Survey. Lower and 

 Middle Cretaceous fishes were collected in Mexico by Dr. David H. 

 Dunkle under the income of the Walcott bequest. An excellent col- 

 lection of cetacean and other mammalian remains from the Miocene 

 of the Chesapeake Bay region made by the late Dr. R. Lee Collins 

 was presented to the Museum by his wife.
