Specimens resulting from the field expedition to the Paleocene 

 (Dragon) and Upper Cretaceous (North Horn) of central Utah and 

 collections from the Uinta of the Uinta Basin, under the direction 

 of C. Lewis Gazin, constituted the outstanding accession of this year. 

 The Paleocene fauna was increased by a considerable number of new 

 forms (Gazin, C. L., Journ. Washington Acad. Sci., vol. 29, pp. 273- 

 286, 1939). Specimens worthy of special mention are a nearly com- 

 plete articulated skeleton of the extinct lizard Polyghiplumodon; two 

 well-preserved crocodile skulls; a complete skull of Bmna in-flata. 

 The Uinta collection formed the bulk of the collection consisting of 

 the usual run of skulls, jaws, and parts of skeletons. 



An unusually well-preserved skull and lower jaw of Trigonias was 

 received in exchange with the Colorado Museum of Natural History; 

 a collection of mammalian specimens from the Pliocene of Pikermi, 

 Greece, was received in exchange with the British Museum of Natural 

 History; a skull and other bones of Buettnerki was received in ex- 

 change with the Museum of Comparative Zoology. 



Two incomplete cetacean skulls from the Miocene of Maryland were 

 presented by Arlton Murray; and a partial skeleton of Turslops 

 from the Pleistocene of Maryland presented by Dr. S. F. Blake. A 

 nearly complete type skull of Felichfhys (Lynn, W. G., and Melland, 

 A. M., Journ. Washington Acad. Sci., vol. 29. pp. 14-20, figs. 1-3, 

 1939) from the Miocene of Calvert County. Md., and 25 dental 

 plates of Phyllodus from the Eocene of Virginia were presented by 

 Dr. W. Gardner Lynn. A slab of fossil bird tracks was presented by 

 V. H. Housholder.
