traces of the typical vertebrate fauna being found near Paul's Valley, 

 Oklahoma, and Blue Grove, Texas. Recognizable fragments were 

 also found south of Abilene, Texas, near Buffalo Gap. 



From this point the observations were carried south to San Angelo 

 and thence west to Pecos, Texas. From Pecos the trip was extended 

 north and west into the Rustler Hills and then to Roswell. From 

 Roswell the party turned west through the Capitan and Oscura 

 Mountains to Soccoro, New Mexico. Near Carthage, New Mexico, 

 Red Beds were examined, at the suggestion of Mr. N. H. Darton, of 

 the U. S. Geological Survey, and remains of vertebrates were found 

 for the first time, which showed these beds to be Triassic in age. 

 Other beds were examined in the Valle del Ajo de la Parida region, 

 northeast of Soccoro. Here typical Permian bones were found in the 

 lower part of the beds, the first that have been found in this region ; the 

 upper part of the beds was shown to be barren and possibly Triassic. 



The expedition resulted in the accumulation of considerable valuable 

 data upon the paleogeography of the Red Beds and in the determina- 

 tion of the age of a part of the Red Beds of New Mexico which have 

 hitherto been called Penno-Triassic. 



Hay, Oliver P., U. S. National Museum, Washington, District of Columbia. 

 Investigation of the vertebrate paleontology of the Pleistocene epoch. (For 

 previous reports see Year Books Nos. 11-14.) 



During the past year Dr. Hay has pursued his investigations on 

 the vertebrate paleontology of the Pleistocene epoch in North Amer- 

 ica. The holding of the Panama Pacific Exposition at San Francisco 

 offered the opportunity to visit various museums on that coast. Small 

 collections were examined at Salt Lake City and at Portland. Some 

 interesting materials were studied at Leland Stanford University. 

 At San Francisco free access was given to the fossil vertebrate collec- 

 tions at the Museum of the CaUfornia Academy of Sciences and at 

 the Memorial Museum, both in Golden Gate Park. 



However, the principal purpose in going to that coast was to study 

 the materials which have been collected from the asphalt pits near 

 Los Angeles. These materials are principally at the University of 

 California, at Berkeley, and at the Museum of History, Science, and 

 Art at Los Angeles. An astonishing amount of vertebrate remains 

 has been gathered, the study of which will extend greatly our knowl- 

 edge of the life of Pleistocene time. 



Recently Dr. Hay visited Baltimore and Rutgers College, in order 

 to examine various collections. 



A week at the end of October was spent in investigating the verte- 

 brate fauna of Pleistocene beds in Florida in which human remains 

 occur, either by primary or secondary deposition. 



Since the last report a considerable amount of vertebrate remains, 

 other than that mentioned above, has been studied, much of it sent
