AQ REPORT OF NATIONAL MUSEUM, 1910. 
obtained should come into the possession of the National Museum. 
The funds for the expedition on the part of the Institution were secured 
entirely from private sources, and the great collections turned over 
to the Nation as a result of the undertaking, essentially as a donation 
from a few friends, compose one of the largest and most important 
single gifts of natural history specimens ever received. As this mat- 
ter has been fully treated in the report of the Secretary, only a brief 
account of the expedition need be given here. 
Col. Roosevelt was accompanied by his son Kermit. The natural- 
ists designated by the Smithsonian Institution were Lieut. Col. 
Edgar A. Mearns, surgeon, United States Army (retired), Mr. Edmund 
Heller, and Mr. John Alden Loring. The itinerary, as reported by the 
director, was briefly as follows: The party landed at Mombasa, 
British East Africa, on April 21, 1909, and reached Khartum on 
March 14, 1910. It was joined at Mombasa by Mr. R. J. Cuning- 
hame, who remained with it throughout the entire trip, and by Mr. 
Leslie J. Tarlton, who continued with the expedition until it left east 
Africa, both of these gentlemen working zealously and efficiently 
for the success of the expedition. Eight months were spent in British 
East Africa. Collecting was carefully done in various parts of the 
Athi and Kapiti plains, in the Sotik, and around Lake Naivasha. 
Dr. Mearns and Mr. Loring made a thorough biological survey of 
Mount Kenia, while the rest of the party skirted its western base, 
went to and up the Guaso Nyero, and later visited the Uasin Gisbu 
region and both sides of the Rift Valley. Mr. Kermit Roosevelt and 
Mr. Tarlton visited the Leikipia Plateau and Lake Hannington, and 
Dr. Mearns and Mr. Kermit Roosevelt made separate trips to the 
coast region near Mombasa. The expedition left east Africa on 
December 19, 1909, passed through Uganda, and thence down the 
White Nile. Over three weeks were spent in the Lado north of 
Wadelai, and, crossing again into the Lado at Gondokoro, Colonel 
and Kermit Roosevelt remained about 10 days in the neighborhood 
of Redjaf. On the journey from Gondokoro to Khartum, which was 
made in a steamer placed at the disposal of the party by the Sirdar, 
collections were obtained at Lake No and on the Bahr-el-Ghazal and 
Bahr-el-Zeraf. Col. Roosevelt speaks in the warmest terms of the 
generous courtesy shown the expedition and the assistance freely 
rendered, not only by the Sirdar, but by all the British officials in 
_ east Africa, Uganda, and the Sudan, and by the Belgian officials in 
the Lado. 
It is impossible in this connection to give a complete inventory of 
the specimens obtained, as the collections from Uganda and the Sudan 
were not received until after the close of the fiscal year, and had not 
been fully unpacked and assorted at the time of writing. In his 
report, however, Col. Roosevelt gives the following tentative enumera-
