REPORT OF NATIONAL MUSEUM, 1924 87 



revised a paper by Thomas Oldroyd, of Stanford University, on the 

 Pliocene of San Pedro, Calif. 



Dr. Mary J. Eathbun has nearly completed an account of the 

 fossil decapod crustaceans of the Pacific Coast States and Alaska, 

 based on material collected by the United States Geological Survey ; 

 by the State universities of Washington, Oregon, and California; 

 Stanford University; the California Academy of Sciences; the San 

 Diego Society of Natural History, and by various individuals, as 

 well as specimens in the collections of the United States National 

 Museum and the Yale University Museum. 



Dr. T. Wayland Vaughan has continued his work on the Na- 

 tional Museum collection of the larger foraminifera, and hopes soon 

 to begin forwarding his papers for publication. 



Due to absence from the office for nearly six months of the fiscal 

 year, C. W. Gilmore prepared no papers based on museum material. 

 Such time as he has been able to devote to research work was spent 

 on his study of the fossil lizards of North America, the monographic 

 work undertaken under a grant from the National Academy of 

 Sciences. This is now nearing completion. Mr. Gilmore's studies 

 of the dinosaurian collections at the Carnegie Museum, Pittsburgh, 

 upon which he was engaged for a period of six weeks, resulted in 

 the preparation of two papers giving information concerning little 

 known forms from the Morrison formation. These will be pub- 

 lished by the Carnegie Museum. A short paper for the University 

 of British Columbia, descriptive of a new species of Laosaurus, was 

 also completed. 



Dr. J. W. Gidley has revised and completed his paper descriptive 

 of the Proboscidea and Edentata from the San Pedro Valley, Ariz., 

 with important notes on the geology of that region. The revision 

 was made necessary by additional observations and data obtained 

 from a second expedition to the Valley conducted by Doctor Gidley 

 for the American Museum of Natural History. He also reports con- 

 siderable progress in the technical study of the remaining Pliocene 

 material from the San Pedro Valley and the Pleistocene collections 

 from Sulphur Springs Valley, in Arizona. 



Eemington Kellogg, of the Biological Survey, has continued 

 his study of the fossil cetaceans. He has submitted four papers 

 for publication based on this material. Dr. Alexander Wetmore, also 

 of the Biological Survey, has studied certain of the fossil birds, 

 and Dr. O. P. Hay has' continued his researches under the auspices 

 of the Carnegie Institution. 



Dr. F. H. Knowlton completed his monograph on the Miocene 

 flora associated with the Columbia lavas near Spokane, Wash. His
