length of 388 millimeters; postorbital length, 60; and a postorbital 
breadth, flat area, of 24.5. The percentages to total length of skull 
were as follows: Postorbital length, 15.4; postorbital breadth, flat 
area, 6.3; interorbital breadth, 31.7. His comparative relative pro- 
portions for typical massaicus are: Postorbital length, 14.0; post- 
orbital breadth, flat area, 14.5; and interorbital breadth, 38.8 per 
cent of total length. In a study of our series of 24 large males 
from British Kast Africa we find the following facts: The skulls most 
closely approaching typical xliani in the various proportions come 
from widely scattered localities, from the Guas Ngishu Plateau, 
Sotik, and Kilimanjaro regions. The skulls in the series most 
closely approaching the recorded proportions of massaicus come from 
the same three areas. Skulls with the postorbital length 15 per cent 
or more of occipitonasal length (#liani) are as follows: Nzoia River, 
Guas Ngishu Plateau, 15.9; Southern Guaso Nyiro, 15.1; Amala 
River, Sotik, 15.0. Skulls with postorbital length less than 14 per 
cent of occipitonasal length (‘‘massaicus’’) are from Nzoia River, 
13.1; Kedong River, 13.1, 13.0, 11.9; Olarakeri, Loita Plains, Kaba- 
lolot Hill, and other localities in the Sotik, 13.5, 13.6, 13.4, 13.2, 11.9, 
12.3, 13.1, 11.4, 12.4, and 11.9; Taveta, 13.9. Skulls with post- 
orbital breadth, flat area, less than 9 per cent of occipitonasal length 
(eliant skull, 6.3) come from Olarakeri, 7.5; Lime Springs, 8.1; 
Telek River, 8.6, all Sotik; and Taveta, 7.3. The Taveta skull, 
practically a topotype of massaicus, is the nearest approach among 
the 24 skulls to typical exlianv in this character, and all of the four 
skulls with least relative postorbital breadth come from extreme 
southern localities. In the entire series there is no specimen with 
the postorbital breadth, flat area, more than 14 per cent of total 
length of skull (said to be a typical condition in massaicus). True 
zliani is said to have interorbital breadth, measured from center of 
rim of orbits, 31.7 per cent of total length of skull, while in massaicus 
it is 38.8 per cent In our series we find 12 male skulls from Guas 
Ngishu Plateau, Mau Summit and Kedong Valley, the Sotik, and 
from Taveta, Kilimanjaro, with the interorbital breadth less than 
31.7 per cent.of occipitonasal length; and only two skulls, from 
Kedong Valley and Telek River, in which it is more than 34 per cent. 
In his notes on the wart-hog killed at Kapiti Plains Colonel Roose- 
velt has written: ? 
Wart-hogs are common throughout the country over which we hunted. They are 
hideous beasts, with strange protuberances on their cheeks; and when alarmed they 
trot or gallop away, holding the tail perfectly erect with the tassel bent forward. 
Usually they are seen in family parties, but a big boar will often be alone. They 
often root up the ground, but the stomachs of those we shot were commonly filled 
with nothing but grass. If the weather is cloudy or wet they may be out all day
