GERMAN Hast Arrica: I[koma, southeast of, 1 (KH. Clark); Mbala- 
geti River, head of, at western edge of Serengeti Plains, 1 skull 
(EK. Clark); Seregeti Plains, 2 skulls (E. Clark). 
The flesh measurements of an adult male from the Loita Plains 
were as follows: Head and body, 2,000 millimeters; tail vertebra, 
645; hind foot, 515; ear, 200. 
Writing of this animal in the Southern Guaso Nyiro, Colonel 
Roosevelt has said:? 
Wildebeest are the oddest in nature and conduct, and in many ways the most 
interesting, of all antelopes. There is in their temper something queer, fiery, eccen- 
tric, and their actions are abrupt and violent. A single bull will stand motionless 
with head raised to stare at an intruder until the latter is quarter of a mile off; then 
down goes his head, his tail is lashed up and around, and off he gallops, plunging, 
kicking, and shaking his head. He may go straight away, he may circle round, or 
even approach nearer to, the intruder; and then he halts again to stare motionless, 
and perhaps to utter his grunt of alarm and defiance. A herd when approached, after 
fixed staring will move off, perhaps at a canter. Soon the leaders make a half wheel, 
and lead their followers in a semicircle; suddenly a couple of old bulls leave the 
rest, and at a tearing gallop describe a semicircle in exactly the opposite direction, 
racing by their comrades as these canter the other way. With one accord the whole 
troop may then halt and stare again at the object they suspect; then off they all go 
at a headlong run, kicking and bucking, tearing at full speed in one direction, then 
suddenly wheeling in semicircles so abrupt as to be almost zigzags, the dust flying 
in clouds; and two bulls may suddenly drop to their knees and for a moment or two 
fight furiously in their own peculiar fashion.

Two groups of duikers, that may well be recognized as subgenera, 
are represented in the collection. The typical forest duikers (sub- 
genus Cephalophus) include the reddish forms, johnstoni, ignifer, and 
harveyi, and the larger, darker colored spadiz. The smaller blue 
duikers, xquatorialis and musculoides, belong in the subgenus Phal- 
antomba.
