PAPIO ANUBIS. 
53 
The last lower molar of the Fio Hill specimen has only a feebly developed last talon, 
whereas the talon on the same tooth in the Elmetaita baboon is strongly developed 
and the whole tooth 2 mm. longer. 
The skull is fully adult, but the position of the basioccipital suture is still marked. 
The canines are much worn, especially the upper ones, which have been much cut 
away on their interno-posterior surfaces by the action of the first lower premolars. 
The cusps of the molars are also considerably worn away and also the incisors. The 
last upper molar has its posterior border on a line with the palato-maxillary suture, 
and in a line with the middle of the anterior root of the zygoma. There is a short 
(13 mm.) triangular edentulous area behind it. 
[In the above observations on the Anubis-group of baboons it is clearly shown 
that the large black-faced dark green baboons with purple-brown callosities are all 
considered to belong to one widely distributed species, ha'v'ing slightly modified local 
forms which are in themselves variable, and thus none too well-defined. As far as 
the material contained in the Museums of Europe shows, the baboons of Abyssinia 
and the Nile Valley (P. doguera and P. heuglini) may be considered to belong to 
the typical form of Papio anubis ; those of the neighbourhood of Victoria Nyanza and 
Lake Rudolf to a slightly modified form, P. anubis subsp. neumanni ; while a large 
form with strongly developed teeth, ranging from Nigeria to Dar Fertit, may be 
known as P. anubis subsp. olivaceus. —W. E. db W.]
