2,2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 76 



The classic Silurian area, the Island of Anticosti, was made the 

 subject of detailed geological and paleontological surveys by the 

 Canadian Geological Survey, in cooperation with various specialists. 

 To Dr. R. S. Bassler was assigned the study of the large collections 

 of Bryozoa and Ostracoda, the results to be published by the Cana- 

 dian Government, but the type specimens to remain in the National 

 Museum. 



At the request of the Canadian Survey, Mr. C. W. Gilmore was 

 detailed for a period of two months for the purpose of studying and 

 describing dinosaurian remains in the collections of the Survey at 

 Ottawa. 



VcrUhratc Studies zvith the Natioval Park Service.- — At the re- 

 quest of the National Park Service, Mr. Gilmore was detailed to con- 

 duct a paleontological survey of an area temporarily withdrawn from 

 settlement and known as the " Mastodon National Monument," in 

 north central New Mexico. As a result of this investigation and 

 unfavorable report, the area was returned to the public domain. 



Studies of North Carolina Vertebrate Fossils. — On the invitation 

 of the State Geologist of North Carolina, Mr. Gilmore prepared a 

 report on the Extinct Reptilia of the state, to be a part of a forth- 

 coming publication on the geology and extinct life of North Carolina. 



Vertebrate Studies at the University of Alberta, Canada. — For 

 two months during the year 1922, Mr. Gilmore was released from 

 his duties at the National Museum to assist in the arrangement and 

 installation of the fossil specimens in the museum of the University 

 of Alberta, and to describe the dinosaurian remains. 



Cooperation zvith the U. S. Geological Survey. — Cooperative work 

 between the Department of Geology and the U. S. Geological Survey 

 is so constant, and the relationship so close, that specific instances are 

 difificult to enumerate. About one-half of the space allotted to the 

 department is occupied by members of the Survey stafif whose work 

 requires access to the classified collections, utilized as ofiice rooms 

 and for storage of their materials, paleobotanical library, etc. Since 

 the Survey has on its stafif no research workers in vertebrate paleon- 

 tology, all of their collections of this nature must be sent here for 

 identification, and members of our stafif have been detailed to ac- 

 company their field parties in order to identify vertebrate remains 

 and thus assist in the proper determination of formations. In this 

 connection mention may be made of trips by Mr. Gilmore with 

 Messrs. Lee and Stanton in northeastern New Mexico, in 1909 ; with 

 Mr. Lloyd in the Judith Basin, Montana, in 191 7 ; and to northeastern
