112 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1933 



by Dr. A. A. L. Mathews, Oberlin College; examples of the fresh- 

 water limestone crowded with fossils, used to build the new Alormon 

 Church in Washington, secured through the builders; and finally a 

 valuable lot of Tennessee Cambrian fossils collected by Prof. George 

 M. Hall, University of Tennessee. 



The Springer fund purchased the important Keyte collection of 

 Paleozoic fossil crinoids from Colorado. The assistant curator during 

 his field expedition obtained 10,000 to 15,000 fossils in Gaspe and 

 New York. These supplied many important specimens for the bio- 

 logic and stratigraphic series and also needed material for exchange. 

 A trip into the Ohio Valley by the head curator also furnished a 

 valuable lot of late Paleozoic fossils. 



Of the eight accessions of fossil plants, mention may be made 

 of those received from Prof. Ralph Chaney, University of California, 

 which contain many counterparts of types described in several 

 papers. Prof. G. R. Wieland, of Yale, donated two examples of the 

 interesting fern Tempskya, and the Santa Barbara Museum of Natural 

 History gave some Pleistocene plants excellently preserved in asphalt. 



Material resulting from the field expedition of 1932 is of first 

 importance in the division of vertebrate paleontology, especially 

 benefiting the mammalian collections. Specimens worthy of especial 

 mention are: Much of the skeleton of a hawldike bird, of which the 

 skull, lower jaw, pelvis, sternum, and other bones are present, un- 

 questionably the most perfect skeleton of a bird yet collected from 

 the Oligocene of North America; a skull and skeletal parts of Eusmilus, 

 a rare saber-toothed cat of which only three or four specimens were 

 previously known; two articulated skeletons of Mesohippus; two 

 articulated skeletons of Menjcoidodon; one skeleton each of Lep- 

 tomeryx and Ischyromys; 120 skulls, many partial skeletons, articu- 

 lated limbs and feet, in all representing more than 20 genera of verte- 

 brates. Some forms new to science will probably be found when a 

 study is made of these materials. 



Through exchanges arranged with various institutions, the division 

 obtained a number of specimens of outstanding merit. From the 

 American Museum of Natural History came a mountable skeleton 

 of Moropus, a rare mammal from the Miocene of Nebraska, and a 

 skeleton of the giant reptile Gorgosaurus libratus from the Upper 

 Cretaceous of Canada. The former has all the broken and missing 

 bones restored so that the skeleton is ready for mounting. Both 

 genera were previously unrepresented in our collections. The Los 

 Angeles Museum of History, Science and Art furnished a mountable 

 composite skeleton of Equus occidentalism from the famous Rancho La 

 Brea asphalt deposits; and the Colorado Museum of Natural History, 

 Denver, a composite skeleton of the Oligocene rhinoceros, Trigonias 

 osborni. From the Royal Ontario Paleontological Museum were
