EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 17 
In Heller’s journal of the Rainey expedition are the following notes 
on this species at Ndi, October 30, 1911: 
Weather cloudy so that the moon was obscured. Shined with the head light the 
whole way through the bush. Shined five or six small lemurs, four of which I shot. 
Their eyes shone brilliant fire-red and are the most brilliant of all animal eyes. I did 
not hear any of them call. 
At Maji-ya-chumvi the animals were found in the dry acacia bush 
country; here also no call was heard.

Specimens.—Ten, as follows: 
Britrtso East Arrica: Mazeras, 10 (Heller). 
This distinct lemur is not intimately related to Galago braccatus, 
which occurs less than 15 miles inland from Mazeras at Maji-ya- 
chumvi. It is probably more closely related to Galago gallarum 
Thomas! from the Boran Galla country. The skins are very uni- 
formly colored, the limbs scarcely brighter than the back. An 
immature specimen, with the last molar not yet in place, has the tail 
almost blackish, very much darker than in any of the adults. Single 
embryos were found in females collected at Mazeras December 21 
and 22. 
Family LASIOPYGIDA. 
Genus PAPIO Erxleben. 
1777. Papio ERXLEBEN, Syst. Regni Anim., Mamm., p. 15. (P. sphinx Erx- 
leben=P. papio.) 
Five closely related forms of baboons are represented in these col- 
lections. No evidence of direct intergradation is to be found and it 
seems better to treat them all as species until the group is properly 
monographed and their relationships with earlier named forms are 
better understood.
