skull is about intermediate in age between the two skulls of this collection. But if 

 the measurements recorded on the accompanying table above are directly compared 

 with those in Anderson's table of measurements (1. c. p. 40, specimens 1 and 4) it 

 will be seen that the former as a rule are somewhat smaller. If due regard is paid 

 to the changes which are connected with increasing age (conf. above) this difference 

 in size appears to indicate among other things a somewhat shorter snout and less 

 width of the facial parts in the specimens from Guaso Nyiri. It is not excluded 

 that such differences are due to individual variation as the material for comparison 

 is not great and I have therefore used the same subspecific name for my specimens 

 as for the Abyssinian representatives of the anubis-gr oup. 



These Baboons lived in numerous herds in the thornbush country north of 

 Guaso Nyiri. Sometimes they inhabited high and steep rocks and had their strong- 

 hold among gigantic blocks to which they took their refuge when danger threatened. 

 In other places they fled into the dense thornbush in similar cases. In localities 

 where there were no rocks suitable as night quarters the Baboons used to ascend 

 some of the trees growing near the river and sleep in them, and it seemed as if the 

 same trees were used night after night. The reason why a tree is selected for night 

 quarter is evidently because it affords protection against attacks from Leopards. If 

 a man aproached the tree the Baboons bounded to the ground and ran into the thick 

 bush as quick as possible. This happened even if it was so late at night that the 

 sun had set, as I observed myself once when it was so dark that I could not see 

 to aim and shoot. Before they ascended the tree for the night they used to drink 

 their fill in the river. I found that the Baboons in the thornbush north of Guaso 

 Nyiri fed largely on a fruit which had a plum-like appearance. Their ventricles 

 were filled with masticated bits of such »pluras» and the cheek pouches contained 

 intact fruits of the same kind. They were green, of the size of an olive and con- 

 tained a stone like that of a plum. It was, however, no plum as the leaves of the 

 bush which I saw once or twice in early development (otherwise the branches were 

 naked) were pinnate. When not fully ripe it had a very strongly adstringent taste 

 but in fully ripe condition it had a sweetish and not unpleasantly aromatic flavor, 

 something reminding about Italian vermouth.
