under way, and has prepared and submitted three papers for pub- 

 lication, as follows : A new genus and species of sauropodous dino- 

 saur from the Upper Cretaceous of New Mexico ; The mounted skele- 

 ton of Brachyceratops ; and A new fossil turtle from Arizona. The 

 first two have been published, the last is in press. Mr. Gilmore's 

 monographic study of the fossil lizards of North America, under 

 a grant from the Marsh fund of the National Academy of Sciences, 

 has been his chief work of investigation during the year. 



Of specialists outside the Government service whose scientific re- 

 searches have added to the value of the collections, Prof. James Per- 

 rin Smith, of Leland Stanford University, has submitted to the United 

 States Geological Survey for publication a monograph on the Upper 

 Triassic marine invertebrate faunas of North America, which is in 

 large part based on Museum material; Dr. O. P. Hay, of the Car- 

 negie Institution, has continued his studies of the Pleistocene verte- 

 brates ; Dr. Robert T. Jackson has described fossil echini ; Dr. J. A. 

 Cushman, foraminifera; Dr. August Foerste, Silurian cephalopods; 

 Ferdinand Canu, bryozoans; and Drs. Arthur Hollick and E. W. 

 Berry, fossil plants. 



Many outsiders, including graduate students from various uni- 

 versities, have made use of the collections and laboratories during 

 the year. Mr. A. Rodolfo Martinez, of the Geological Institute of 

 Mexico, continued his studies for several months, and Mr. Seitaro 

 Tsuboi, of the Imperial University of Tokyo, spent considerable 

 time in the chemical laboratory, Avhile shorter visits were made by 

 Professors Nakamura and M. Watanabe. Mr. and Mrs. Robert Bar- 

 rett spent three weeks studying collections of California rocks, pre- 

 paratory to teaching in a boys : summer camp in California. 



Prof. Henry Fairfield Osborn and Dr. W. D. Matthew, of the 

 American Museum of Natural History, studied our vertebrate col- 

 lections in connection with their special researches; Dr. Ralph 

 Chaney, of the University of California, Miss E. Round and Miss 

 Weston, of Brown University, and Prof. A. E. Douglas, of the Uni- 

 versity of Arizona, have examined the paleobotanic collections, the 

 last named studying especially the fossil woods with reference to 

 their bearing on past climates. 



In addition to research work on the collections, all members of 

 the staff have been called upon to do a considerable amount on ma- 

 terials submitted by outsiders for examination and report. Within 

 the year, 473 lots have been reported on, 395 of which were geological 

 or mineralogical, and 78 paleontological. 



Distributions. — For purposes of scientific research or as loans for 

 exhibition or other usage, there were sent out during the year 39 

 lots of material, aggregating 2,978 specimens, and 500 pounds of 

 material in bulk. These were distributed amono- workers in other
