Upper Nile Valley. Mansfield Parkyns ^ observed it in Tigre in a spot highly 
characteristic of its proclivities, viz., a deep well-wooded ravine with a brook running 
through it. On the banks of the Nile and on the margin of the desert it is found 
only where there is vegetation, and generally trees. [In some recent letters to 
Dr. Anderson he is told that since the war with the Dervishes the apes have been 
scared from the banks of the Nile, which have been denuded of trees.—Gr. S. A.] Its 
food consists largely of the fruits and leaves of three genera of trees, viz., Zyzyplius, 
Ficus^, and Tamarindus, and the gum of the latter, but it robs the Sorghum fields and 
the gardens of the natives and is occasionally very destructive. 
It is known in Arabic as (‘Abu-Lang’), which is the name generally applied 
to it in the Nile Valley, but it is occasionally also known under the same name in 
Abyssinia. According to Plartmann^, the term ‘ Nisnas-cughajir ’ is also given to it. 
Salt, Riippell, Plarris, Parkyns, Heuglin, Brehm, and Hartmann state that it is known in 
Amharic as ‘ Tota’; on the authority of Lefevre it is called ‘ Amado ’ and ‘ Hhamedo ’ in 
the Tigre modification of Geez. Salt says that it is called in Tigre ‘ Alesto,’ and Parkyns 
and Heuglin ‘Woag.’ It is noticeable, however, that Hemprich and Ehrenberg apply 
‘ Tota ’ and ‘ Halestijo’ or ‘Alectijo,’ evidently the ‘Alesto’ of Salt, to the baboon, Paggio 
hamadryas.

General colour of the first of these specimens is cold greyish, due to the black and 
white speckled character of the head, trunk, and outsides of the limbs. Whiskers, 
chin, throat, chest, under surface of belly, and lower portion of sides of body pure white. 
There is a not very well-marked greyish-yellow frontal band, margined below with 
long black superciliary hairs. The face is dusky and covered rather thickly with short 
adpressed dark brownish hairs on the nose and external to it from the interorbital 
space downwards, the hairs along the upper lip being more or less whitish, also those 
on the chin. Although the general hue of the top of the head and of the back is 
cold greyish, these parts in certain lights manifest a slightly greenish tint. On the 
extremities, the grey passes into greyish brown on the upper surface of the feet. The 
tail on its upper surface is greyish brown, darkest at the base, whilst the tip is greyish 
with a faint yellowish tint. Owing to this specimen being stuffed in a seated position, 
to measure it was useless. 
The second specimen, from the White Nile (no. 63), is much the same as the previous
