384 Field Museum of Natural History — Reports, Vol. IV. 



Oryx, 2 Dik Dik, 1 Klipspringer, 4 Gerenuk, 1 Buffalo, and 1 Jackal. 

 Mr. E. B. Williamson of Bluff ton, Indiana, presented a number of 

 birds during the year, and his continued interest is much appreciated. 

 Judge R. M. Barnes of Lacon, Illinois, presented a body of the rare 

 Trumpeter Swan. An albino crow was purchased. The Osteological col- 

 lection was enlarged by 445 skulls cleaned for the study collection, and 

 5 skeletons were prepared and installed in the exhibition collection. 



expeditions and field Work- — At the beginning of the year the 

 Museum had two zoological collectors in the field: Malcolm P. Ander- 

 son in Venezuela, and Robert H. Becker in Brazil. In January Mr. 

 Anderson proceeded to Peru and worked in high altitudes in the Andes 

 Mountains east of Chimbote, later going to Lake Junin (altitude 

 14,000 feet). After leaving Lake Junin May 7th, he spent a month 

 collecting in the vicinity of San Ramon on the Rio Chanchamayo, and 

 sailed for home early in June. While Mr. Anderson secured valuable 

 material, the specimens were less in number than could have been 

 expected, owing largely to a series of unfortunate accidents. In Janu- 

 ary, Mr. Becker proceeded from Rio de Janeiro, Brazil, to Lagoa 

 Santa in the State of Minas Geraes, where he made an important col- 

 lection of birds and mammals. He then proceeded up the Rio San 

 Francisco to Barra, and from there pushed on up the Rio Preto to and 

 beyond Formosa, a small native town in a very little known region in the 

 interior of Brazil. This country has not been worked by collectors, and 

 it is unfortunate that after surmounting difficulties in reaching there, 

 his stay had to be limited to two weeks. Interesting mammals 

 and birds were secured, some of which are new and will be the subject of 

 a publication in due time. Coming down the Rio Preto on a raft, which 

 he built, Mr. Becker reached Barra safely, and from there went on to 

 Bahia and took a steamer to Trinidad, where he had been directed to 

 secure material for a group of Oil Birds (Steatornis caripensis). The 

 birds, eggs, nests, and accessory material were obtained, also photo- 

 graphs of the caves in which the birds live, and the group is now in 

 process of construction. 



installation, rearrangement, and permanent Improvement. — A most en- 

 couraging feature of the work performed in the Department of 

 Anthropology during the current year is that, despite the reduction of 

 the force rendered necessary in January, the progress of installation 

 has been fully maintained to a remarkable degree, and, in fact, the work 

 in every line of activity has been pursued with energy and devotion. 

 A total of 70 new cases has been placed on permanent exhibition, all 

 fully and completely labeled. The material installed in these cases is 

 distributed as follows: Southwest Ethnology, 5 cases; New Hebrides, 12
