to it, because of its habits. The case is directly the reverse 
of that of the steinbok, which does continually hide and 
skulk and try to escape observation, and yet has a colora¬

Nyiro River and the northern slopes of Mount Kenia north¬

closely allied to the Abyssinian klipspringer, with which 
it is in agreement in the character of the hornless female,
