324 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 9Q 



peditions have covered a wide area, collections having been made 

 in Alabama, Alaska, Arizona, Cuba, Florida, Idaho, Indiana, Mary- 

 land, Montana, Nebraska, New Mexico, Oklahoma, Siberia, South 

 Dakota, Utah, Virginia, and Wyoming. 



Although much of the exploratory work of later years has been 

 done in well-known fossil-producing areas, these collecting activities 

 have also resulted in the development of important new fossil areas 

 and faunas. The more important of these are: Jackson, Eocene 

 fauna, near Melvin, Choctaw County, Ala. (1894, 1896, 1929) ; the 

 Cumberland Cave Pleistocene fauna near Cumberland, Md. (1912, 

 1913, 1914, 1915) ; Paleocene fauna from Sweet Grass County, Mont. 

 (1908, 1909, 1910, 1911, 1934) ; Pliocene and Pleistocene faunas of the 

 San Pedro Valley, Ariz. (1921, 1936) ; footprints from the Permian 

 of the Grand Canyon, Ariz. (1924, 1926, 1927) ; fauna of the Upper 

 Cretaceous, Two Medicine formation, Mont, (1913, 1928, 1935) ; 

 Pliocene fauna and development of the famous Plesifpus Quarry 

 near Hagerman, Idaho (1929, 1930, 1931, 1934) ; fauna of the Upper 

 Cretaceous, North Horn formation, and Paleocene, Dragon forma- 

 tion of the Wasatch Plateau region of central Utah (1937, 1938, 1939, 

 1940) ; Miocene fauna of the Chesapeake Bay area (1905-1940). 



Although early collecting was intermittent and consisted largely 

 in accepting opportunities as they arose, with the exception of the 

 Marsh collecting parties for the Geological Survey the work of re- 

 cent years has been planned witli the idea of filling in gaps and of 

 rounding out the permanent collections, so that they will be more 

 fully representative of all the better-known North American faunas 

 and fossil-producing areas. As a result of this planned collecting, 

 the vertebrate collections of the National Museum are gradually 

 reaching a standard that is in keeping with the national character 

 of the Institution.
