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-group. 
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 gigantice 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 »plums» 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.
