The type specimen of Neurankylus wyomingensis from the Upper 

 Cretaceous of Wyoming was transferred by the United States Geo- 

 logical Survey (Gilmore, C. W., Proc. U. S. Nat. Mus., vol. 56, 

 p. 113,1920).*

The Fort Union collection from Montana was further increased by 

 the purchase of 400 specimens from the collector A. C. Silberling 

 (Simpson, G. G., U. S. Nat. Mus. Bull. 169, pp. 1-279, 1937) . A most 

 important collection of Pleistocene mammals, representing 22 genera, 

 several of which were new, was made by James W. Gidley from the 

 "Cumberland Cave" near Cumberland, Md. A collection of Pleisto- 

 cene fossils made by Copley Amory, Jr., for the Museum along the 

 Old Crow River, Yukon Territory, was transferred as a gift from the 

 Smithsonian Institution. It contained a unique specimen, the foot 

 bone of a camel, the first evidence of the former occurrence of this 

 animal north of the Arctic Circle (Gidley, J. W., Smithsonian Misc. 

 Coll., vol. 60, pp. 1-2, 1913). C. P. Snyder presented a skull of 

 Equus niohrarensh alashae (Hay, O. P., Smithsonian Misc. Coll., 

 vol. 61, No. 2, pp. 1-18, 1913) and a mastodon tooth, both from the 

 Pleistocene of Alaska. Cetacean specimens, including the type of 

 Panetobalaena 'palmeri (Kellogg, R., Proc. U. S. Nat. Mus.. vol. 63, 

 pp. 1-14, 1924) from the Calvert, Miocene, of the Chesapeake Bay 

 region, were presented by William Palmer and A C. Weed of the 

 Museum staff. 



An upper molar of a mastodon and a skull of Symhos cavifrons^ 

 both from the Pleistocene of Mason County, 111., were presented by 

 John Wiedmer (Hay, O. P., Carnegie Inst. Washington Publ. ;'>22, 

 pp. 103-104, 1.923).

The important accession of this year was a collection of dinosaur 

 remains collected by Charles W. Gilmore, working under the auspices 

 of the United States Geological Survey, from the Two Medicine 

 formation. Upper Cretaceous, of Montana, inside from filling an 

 important gap in the collections, this assemblage furnished the type 

 of a new genus and species {BrdchyGeratops mo n fane mis) of the 

 Ceratopsia (Gilmore, C. W., U. S. Geol. Surv. Prof. Pap. 103, pp. 

 1-38, 1917). 



Another installment of Pleistocene fossils from the Cumberland 

 Cave deposit was collected by James W. Gidley. The specimens 

 included a mountable skeleton of Pl-atygonns cumherlandensh (Gid- 

 ley, J. W., Proc. U. S. Nat. Mus., vol.' 57, pp. 651-678, 1920), and 

 many good skulls and articulated limbs and feet, in part belonging 

 to genera and species not previously recognized from this locality 

 (Gidley, J. W., and Gazin, C. L., U. S. Nat. Mus. Bull. 171, pp. 

 1-99.1938).
