forested valleys in the true Temperate Zone. Here quetzals, jays, 

 and a variety of little-known, high-mountain birds ranged through 

 trees grown heavily with- moss and dense undergrowth constantly wet 

 from misty rain. Morning temperatures ranged down to 45° F. 



Following this, a few days were devoted to Cerro Chame, a low, 

 isolated mountain on the coast below Bejuco, and a day each to the 

 La Jagua marshes, near Pacora, and the high ridge of the Cerro Azul, 

 beyond Tocumen. The latter mountain is especially interesting as 

 the haunt of an unusual species of hummingbird, known first from its 

 discovery by E. A. Goldman during investigations for the Smithsonian 

 in 1912, and named Goldmania violiceps. 



The field investigations concluded with two days on Barro Colorado 

 Island, the Smithsonian biological station in Gatun Lake, the time 

 being devoted mainly to observation from cayuco along the island 

 shoreline. The work, during which Armageddon Hartmann served 

 again as assistant, was completed on April 5. During the 3-month 

 period notes were secured on approximately 400 species of birds. 



During the last week of September 1954, Dr. David H. Jolinson, 

 acting curator, division of mammals, devoted a week at the Chicago 

 Natural History Museum to the study of types and other specimens 

 of mammals in that collection from Formosa, Borneo, and Siam. On 

 the recommendation of the Commission on Hemorrhagic Fever, 

 Armed Forces Epidemiological Board, military air transportation to 

 London and return was furnished on March 29, 1955, to Dr. Johnson 

 for the purpose of studying the types and other related specimens 

 from northeastern Asia in the collections of the British Museum 

 (Natural History). This commission requested Dr. Jolinson, with 

 the assistance of Lt. J. Knox Jones, to undertake a review of Koreap 

 mammals collected by Army field teams between 1952 and 1954. 



From March 27 to April 8, 1955, Dr. Charles O. Handley, Jr., 

 assistant curator, division of mammals, was engaged in comparative 

 studies of foxes, bats, and marsupials in the collections of the Museum 

 of Comparative Zoology and the American Museum of Natural 

 History for tlie purpose of advancing completion of revisionary 

 studies. 



Dr. Ernest A. Lachner, associate curator, division of fishes, assisted 

 by Frank Schwartz of the University of Pittsburgh, collected in the 

 interval between September 9 and 14, 1954, several thousand fishes 

 in furtherance of his projected study of the fresh- water fishes of the 

 mountain streams of Virginia, the Carolinas, and Georgia. 



Dr. J. F. Gates Clarke, curator, division of insects, left Washington 

 on May 25, 1955, for an extended field trip to the Pacific Northwest, 

 financed by a grant-in-aid from the American Philosophical Society. 

 This research project involved the collection of larvae of small moths
