INTRODUCTION. 
The first part of this bulletin, published August 16, 1918, dealt with 
the mammals of the orders Insectivora, Chiroptera, and Carnivora 
contained in the East African collections of the United States National 
Museum. The second part, published May 16, 1919, dealt with the 
orders Rodentia, Lagomorpha, and Tubulidentata. This third part, 
which completes the work, consists of reports on the specimens from 
East Africa belonging to the Orders Primates (lemurs and monkeys), 
Artiodactyla (swine, hippopotamuses, giraffes, buffaloes, antelopes, 
and their allies), Perissodactyla (zebras and rhinoceroses), Probos- 
cidea (elephants), and Hyracoidea (hyraxes). 
The plan of arrangement of the text is the same as in the earlier 
parts, and has been fully explained in the introduction to Part I. 
The geographical limits are also the same. All specimens of mam- 
mals from Eritrea, Somaliland, Sudan, Abyssinia, Lado Enclave, 
Uganda, British East Africa, and German East Africa, including 
Zanzibar, contained in the collection have been critically examined 
and listed. The territory included is shown in Figure 1. 
Since the publication of the earlier parts, there have been con- 
spicuous changes in the political aspect of Africa. As one of the 
results of the World War the names of countries, as well as their 
boundaries, have been altered. The principal changes that affect the 
region covered by this report are as follows: The greater part of 
British East Africa is now known as Kenya Colony; the strip of coast 
land, 10 miles wide, leased from the Sultan of Zanzibar, remains a 
Protectorate under the title of Kenya Protectorate. Most of the for- 
mer German East Africa, now under British control, is known as 
Tanganyika Territory. A small section of the northwestern part, 
including Ruanda and Urundi, is transferred to. Belgium; and 400
