From the end of May to the middle of June 19'12, Frank M. Setz- 

 ler, head curator of the department of anthropology, was detailed 

 to the National Park Service for the purpose of directing a rapid 

 archeological reconnaissance within the canyons formed by the 

 Yampa and Green Rivers in northwestern Colorado and eastern 

 Utah, to locate and evaluate the prehistoric caves, shelters, and vil- 

 lage sites within an area that may be inundated eventually, if pro- 

 posed dams are built along these rivers. The expedition traveled by 

 boat through the various rapids within the canyon, and discovered 

 and tested numerous sites. A detailed report covering the results 

 of these investigations was prepared and submitted to the National 

 Park Service before the close of the fiscal year. 



Biology. — In March, M. A. Carriker, Jr., carrying on the work 

 begun last year with Dr. Wetmore, continued the study and collec- 

 tion of birds in northeastern Colombia. From Codazzi, in the De- 

 partment of Magdalcna, he traveled into the mountains to establish 

 a base that gave access to the higher peaks along the Venezuelan 

 border. These investigations were supplemented by collections from 

 the lowland areas, which were of value in connection with materials 

 obtained in March 1941 at Caracolicito. in the drainage of the Rio 

 Ariguani. At the close of the fiscal year these studies, which were 

 made possible by the W. L. Abbott fund of the Smithsonian Insti- 

 tution, were still in progress.

 ary 1 to May 28 in Venezuela in connection with the program of the

 he consulted with various scientific groups, and the remainder of 

 his time in the Maracaibo Basin, studying the fish fauna of tliat region.

 Lago Petroleum Corporation at ]Maracaibo and Lagunillas. For 8' 

 days Dr. Schultz collected in the valleys of the Rio Motatan, Rio 

 Chama. Rio Catatumbo. and Rio Torbes. all in the Andes. He ob- 

 tained about 10,000 fish specimens, including approximately 115 

 species, and other natural-history material. The fish collection is 

 the most complete one tliat has been made in this region and will 

 afford valuable new information in this field. 



Dr. E. A. Chapin, curator of insects, worked for 6 weeks in 

 Colombia, in connection with the above-mentioned program of the 

 Department of State. For 5 weeks he was in the vicinity of Bogota,
