58 REPORT OF NATIONAL MUSEUM, 1921. 
During the year two shipments were received from Mr. Hoy. A 
total of 571 mammals, well prepared, several of which were hitherto 
unrepresented in our collection, together with a series of skeletal 
and embryological material. The birds numbered 534 specimens and 
represented considerably over 100 species and subspecies. A num- 
ber of interesting reptiles, amphibians, fishes, and marine inverte- 
brates were also collected. 
The Smithsonian African expedition, the organization and start- 
ing out of which were detailed in my last year’s report, completed 
its biological work on July 14, 1920. 
In the vicinity of Cape Town, Mr. Raven was able to collect only 
insects and invertebrates, and from there he went to the Addo Bush, 
where 19 days were spent in collecting small mammals and birds. 
Going through Durban and Johannesburg, Mr. Raven spent two 
weeks collecting at Ottoshoop in the Transvaal, after which he pro- 
ceeded to Victoria Falls, and from there he left for the Kafue River 
region, where he camped for several weeks. After spending some 
weeks along the Congo, he reached Lake Tanganyika, where camp 
was made for about a month. The next stop of any length was in 
Uganda, where a few days over a month were spent in collecting in 
the Budongo Forest. 
Though not numerically large, the collections are of unusual in- 
terest on account of the manner in which they supplement those ob- 
tained by other expeditions in which the Smithsonian Institution has 
been interested. Among the most important material may be men- 
tioned 699 mammals (including 272 specimens from South Africa, 
a region hitherto very imperfectly represented in our collection; 152 
from Lake Tanganyika; the chimpanzee of Uganda) ; 567 birds, 206 
reptiles, and 193 fishes, the latter from Lake Tanganyika. About 
100 lots of mollusks were also collected. 
A few new expeditions undertaken during the year have been in- 
strumental in adding valuable material to our collections. 
Late in 1920 Dr. W. L. Abbott undertook personally another ex- 
pedition, this time visiting the north side of Santo Domingo (Villa 
Riva, Pimentel, Catui, Mao in the Yaqui Valley, and several points 
on the Samana Peninsula) and returning in May, 1921. He brought 
back a small but select collection of birds, but his main efforts were 
devoted to the collecting of plants, approximately 4,000 of which 
have been received and will doubtless prove of great value. 
The Biological Survey, Department of Agriculture, anxious to ob- 
tain first-hand information concerning the movements of North 
American migratory birds in southern South America, in the spring 
of 1920 sent Dr. Alexander Wetmore to Argentina, where he col- 
lected information and specimens in the Provinces of Chaco and For- 
mosa, as well as in the Paraguayan Chaco, during the winter season.
