on the dorsum of the hand. The long hairs are rather lighter in colour, their bases 
being brownish, out passing into yellow-grey; the apex of each being black with a 
yellow band below it, succeeded by a dark brown band. The throat is greyish white 
and the cheeks yellowish grey. There is in this young female an absence of the same 
vivid yellow generally present in the males on the outsides of the hind limbs. The 
tail is browmish grey, and the under parts are more or less silvery grey. The animal, 
although young, measured 750 mm. from snout to vent, and the tail 270 mm. 
Matschie, when he described it, considered it to be nearly related to P. hahuin and to 
P. cynocephaUis, each of wdiich he regarded as distinct, but that it differed from both 
in colour. He stated, how^ever, that Dr. Stuhlmann had called his attention to the 
fact that the baboon of East Africa differs in its colouring according to its age and sex, 
He gave the following as a diagnosis of the characters of this female:—“ Cynocephalns, 
sordide olivaceo-canus, dorsi capillis elongatis, cauda brunneo-cana, artubus externe 
ffavo-brunneo lavatis.” 
Five years afterwards ^ he identiffed this young female from Unguru and the skull 
from Ukami with P. thoth, Ogilby; and as he had received further materials from the 
interior of German East Africa, he was led to regard the two skulls, male and female, 
from Usukuma as belonging to a distinct species, for which he suggested that the term 
langheldi should be reserved to the exclusion of the real type from Unguru 
With the invaluable assistance of Mr. Matschie, I was enabled to go over the wEole 
of the material contained in the Berlin Museum, with this result, that I am disposed 
to agree with him that the female skull from the neighbourhood of the Victoria Nyanza 
belongs to a baboon of the Papio anubis type, allied to, if not identical wuth, his 
P. nemnanni^ and distinct from the Unguru baboon, Avhich is unquestionably P. cyno- 
cephalus. We may therefore accept the Unguru baboon as undoubtedly the type of 
P. langheldi. About 90 kilom. to the Avest of Unguru, the district Avhere P. langheldi 
was obtained, is Mpapwe, whence three skins of this baboon exist in the same 
collection. About 220 kilometres to the south of the latter locality is Perondo, also 
represented in the same collection by another skin and skull; and still further 
south, at the northern end of Lake Nyassa, is the German station of Langenberg, 
from which another skin was presented to the same institution. 
The skin collected at Perondo, 350 kilom. inland from the coast-line, presents the 
following characters:— 
The animal Avas an adult male with a well-deA^eloped mantle on the shoulders, 
the hair on the lumbar and sacral regions being very much shorter. The hairs on the 
upper surface of the neck, and on part of the shoulders and humerus, are also long, 
and the sides of the body, and outsides and hinder margins of the hind limbs, are
