258 Lloyd's natural history. 



Baboons are confined to the African continent and to 

 Arabia, to the region, indeed, termed Ethiopian, as defined 

 by Sclater and Wallace. They live chiefly on the ground, 

 especially in rocky and barren hills, and less frequently among 

 trees, for which their equally long front and hind limbs are not 

 so well adapted. Mr. H. H. Johnson, C.B., now H.M. Com- 

 missioner in Nyasa-land, found, however, on his Kilimanjaro 

 Expedition, that Baboons were singularly abundant in the big 

 trees at Taveita, on the rise to that mountain. Their food consists 

 of fruits and Lizards, but principally of insects, which they 

 search for under stones, turning these over with their hands. 

 They are, indeed, nearly omnivorous, as the reader will have 

 gathered from Dr. Hclub's observations.
