fornia, Oregon, Washington and British 

 Columbia, securing data and photographs for 

 the purpose of the construction of a number 

 of relief models, showing most interesting geo- 

 logical formation in these states. Associate 

 Curator Reeds is working in the vicinity of 

 New York, collecting data for a museum ex- 

 hibit to show the "Climates Past and Present," 

 and Mr. Foyles is continuing his studies in 

 northwestern Vermont on the Fort Cassein 

 terrain. 



For the department of vertebrate paleon- 

 tology, an expedition in charge of Albert 

 Thomson is at work in western Nebraska, seek- 

 ing fossil mammals from the Snake Creek beds 

 of the Pliocene age. Working in the same 

 vicinity is Curator Matthew, who will shortly 

 he joined by Mr. Olsen. Mr. Barnum Brown, 

 who is well known from his success in securing 

 most of the Brontosaurian material now on ex- 

 hibition in the musemn, is at work in the 

 Siwalik Hills of India, obtaining fossil mam- 

 mals and other invertebrates from a famous 

 fossil bearing formation. In the late autumn, 

 it is the intention of President Henry Fairfield 

 Osborn to join the Third Asiatic Expedition, 

 which has connected with it, in charge of 

 paleontology, Mr. Walter Granger. Working 

 with Mr. Granger at the present time are Pro- 

 fessors Chai-les P. Berkey and Frederick K. 

 Morris. Already extensive shipments have 

 been made bj' this expedition. Mr. Childs 

 Frick, one of the trustees of the institution, 

 will continue fossil collecting in southern Cali- 

 fornia, where he has already obtained an ex- 

 tensive collection from the Pliocene. 



Dr. Frank M. Chapman, curator of the de- 

 partment of birds, accompanied by Mr. George 

 K. Cherrie and Captain O'Connell, are in 

 Ecuador continuing their studies on the distri- 

 bution of bird life in the Andes. They will 

 iii'st investigate southern and southeastern 

 Ecuador and will then conclude their work by 

 a boat trip from Guayaquil along the coast to 

 Paita, Peru. Assisting in the investigations in 

 bird life in Ecuador, Henry Watkins is now 

 engaged in the mountains of Peru. His latest 

 shipment comes from the humid regions north- 

 east of Lake Junin. Ernest Holt, formerly of 

 the United States Biological Survey, is engaged 



in collecting birds and mammals for the mu- 

 seum in the mountains of eastern Brazil. A 

 collection was recently received from him 

 which was secured around Mt. Itatiaya. Later 

 Mr. Holt will explore still higher peaks. The 

 museum's representation of bird life from this 

 important region has until now been confined 

 entirely to specimens in the old Prince Maxi- 

 milian Collection. Jose G. Correia is under- 

 taking the collection of birds at the Cape Verde 

 Islands, and Rollo H. Beck, who is working 

 under the auspices of the Whitney South Sea 

 Expedition, is collecting in the Society Islands. 

 Mr. Beck is accompanied by Mrs. Beck and 

 Mr. Quayle. Mr. Griscom is doing work in 

 New Foundland, while other members of the 

 department are engaged in the local field. 



The department of mammals has G. H. Tate 

 in Ecuador. He will later be joined by an 

 assistant in order that more intensive investi- 

 gations of the life of mammals in this region 

 may be studied. H. C. Raven, who accom- 

 panied Dr. W. K. Gregory to Australia last 

 year, has nearly completed a systematic collec- 

 tion in Queensland and will next go to the 

 great Nullaboa Plain in South Australia. He 

 has already obtained for exhibition and study 

 a series of the marsupial mammals. 



In September, Herbert Lang, assistant cura- 

 tor of African mammals, will leave for British 

 Guiana for a three months' trip. At George- 

 town he will join William La Varre and will 

 go up the Essequibo River through the diamond 

 mining district along the Mazaruni. He hopes 

 to go through the savannah country and Mt. 

 Koraima. By studies of the conditions in this 

 section at first hand, Mr. Lang has an oppor- 

 tunity to compare the ecological conditions in 

 the great South American forests and savan- 

 nahs with those of equatorial Africa, a com- 

 parison which has long been needed in connec- 

 tion with the preparation of his reports on his 

 Congo expeditions. 



Dr. F. E. Lutz, of the department of ento- 

 mology, is engaged in work in the vicinity of 

 Boulder, Colo. F. E. Watson, of this depart- 

 ment, recently returned from a four months' 

 trip to Haiti where he secured approximately 

 eleven thousand specimens of the lower inver- 

 tebrates, chiefly insects, and about three hun-
