SECRETARY'S REPORT 33 



Gifts from collectors outside the Smithsonian Institution include: 

 221 type specimens of planktonic Foraminifera from Recent bottom 

 sediments of the Pacific Ocean from J?kliss Frances Parker of the 

 Scripps Institution of Oceanography; 1,000 Upper Cretaceous mol- 

 lusks from Tennessee and Mississippi arranged by Margaret J. Hall 

 through Mid-South Earth Science Club ; 6,000 Silurian brachiopods 

 from Czechoslovakia collected by Dr. A. J. Boucot of the California 

 Institute of Technology; 134 type specimens of Foraminifera from 

 the Cretaceous Adelphia Marl of Arkansas from Dr. H. C. Skinner, 

 Tulane University; 500 specimens of Middle Devonian brachiopods 

 and corals from northern Ohio from Bernard Keith ; 100 Early Devo- 

 nian invertebrates from Flute Cave, W. Va., from the Potomac Spele- 

 ological Club; 50 specimens of early Ordovician brachiopods from 

 Kielce, Poland- from Dr. R. B. Neuman; 23 rare and unusual Miocene 

 mollusks from Virginia from Mr. and Mrs. W. M. Rice; and 62 thin 

 sections of type Foraminifera from the Mississippian of southern 

 Illinois and Kentucky from Mrs. D. E. N. Zeller of the University 

 of Kansas. 



Outstanding specimen exchanges brought 76 specimens of Pliocene 

 moUusks from the Scaldesian formation of Belgimn, through Dr. S. 

 Amelmckx; 99 specimens of fossil invertebrates from Argentina 

 through Dr. A. J. Amos ; 13 anunonites from the Cretaceous of Russia 

 through Dr. D. P. Naidin ; and the Harris collection of type specimens 

 of fossil crinoids, from the University of Houston. 



In the division of vertebrate paleontology, the major specimens of 

 fossil vertebrates accessioned this year consist of two skulls and a 

 skeleton of three different tetrapods from the Permian of Texas, 

 and two partial skeletons of Mississippian amphibians, probably new 

 to science, from West Virginia. The Texas material is of superior 

 quality and will be most useful in morphological work. These speci- 

 mens were collected by associate curator Nicholas Hotton III and 

 James Kitching of the University of the Witwatersrand, Johannes- 

 burg, South Africa. 



A remarkably good collection comprising remains of a variety of 

 Eocene mammals found by W. L. Rohrer in the Big Horn Basin 

 of Wyoming was transferred from the U.S. Geological Survey. Note- 

 worthy are skull portions of the large pantodont Goryphodon^ jaws 

 and maxillae of the early horse Eyracothermtn and the lemuroid 

 primate Pelycodus^ and the greater part of a skull of a rare leptictid 

 insectivore. 



Science a7id technology. — ^The division of physical sciences received 

 from the Bell Telephone Laboratories the apparatus used by Dr. 

 Clinton T. Davisson in his 1927 investigations of interference phe- 

 nomena in crystals irradiated by electrons, for which he received
