contrast to their sombre livery. The Red Colobi are the rarer, and 
there is no considerable collection of them in any Museum, but the 
black species are evidently more easily captured, and in a few collections 
are fairly well represented. 
The Guerezas are forest loving animals, and striking as the 
coloring of their coats may be, and large as is their size, they are not 
easy to see amid the foliage, thus illustrating the well known fact, 
that the most brilliantly colored creatures, such as the tiger and zebra, 
are by no means the most conspicuous. Not many individuals are 
found together, and they usually keep to the tops of the loftiest trees. 
Their food consists of various fruits and leaves, and their peculiar 
stomachs are admirably fitted to digest the latter, for great quantities 
are rapidly swallowed at a time, as monkeys always eat in a hurry, 
whether impelled by greediness or fear. The Black Colobi appear to 
bear extremes of temperature without difficulty and are found at an 
elevation of 9,000 feet on the great Uganda mountain of Ruwenzori, 
and on the Elgon Plateau; but they are equally at home in the tropical 
forests of the same Protectorate, bearing well the extremes of cold 
and heat. In Uganda, according to *Sir Harry Johnston, these 
monkeys live entirely on leaves, and seem to dislike animal food. 
Some native tribes eat them, and among the Andorobo it is the favorite 
article of diet. As a rule they do not live long in captivity and require 
much care; since deprived of an arboreal existence, they are not 
reconciled to a life upon the ground. Of the Red Colobi very little is 
known, as but few Europeans have met with them in the wild state.
