CEECOPITHECUS ^ETHIOPS.

the land of the Troglodytae, to the south of Ptolemaicus Theron; and there was, likewise, 
the town Saba, somewhere in the immediate vicinity of the present Massowah. The 
Grivet might well be associated with the last-mentioned locality, as it was situated in 
the very region over which this monkey is widely distributed. The appropriateness of 
Linnaeus’s name thus becomes apparent. 
[There can be no question as to the species indicated by Linnaeus in his account of 
Hasselquist’s journey to Egypt and Palestine, published after the death of that 
traveller. In the 10th edition of the ‘ Systema Naturae ’ the same name (S. cethiops) 
is applied to this animal, which is unquestionably the green monkey of the Upper Nile 
Valley and Abyssinia. In the 12th edition of the ‘Systema’ Linnaeus unfortunately 
only mentions this name in connection with a variety of another species from West 
Africa. 
Simia sabcea, Linn., ed. 12, should therefore lapse into a synonym of Cercopithecus 
(Bthiops, for Egypt is referred to primarily as the habitat, and there is no mention of 
yellow in the whiskers or tail, the colour of the latter being described as “ cinerea ” 
and “ cana ” = hoary. 
For some unknown reason Simia cethiops has been applied by most modern writers 
to a species of Mangabey {Cercocehus). There is nothing in the original description 
applicable to any member of that genus, while every word agrees perfectly with 
the monkey under notice, which, as Hasselquist mentions, is so frequently seen in 
captivity in Egypt. It has been said, in excuse for this view, that Linnaeus described 
the eyelids as white. This is an error, for not only did the white band mentioned not 
affect the eyelids, but it was placed above the eyebrows. The description runs: 
“ linea Candida tenuis, proximo super supercilia, transvaliter per frontem extensa.” 
The Mangabey referred to has no claim, therefore, to the name cethiops, and should be 
called Cercocebus lunulatus, Temm. (Esquis. Guin. 1853, p. 37).— W. E. de W.] 
The following are some of the facts bearing upon our knowledge of this species 
since the days of Linnaeus:— 
Browne in his account of the wild animals met with in Dar-Eur, mentioned a 
monkey under the name of Siniia cethiops, the term applied by Hasselquist to this 
species, and also under the native designation of ‘ Abu-lang,’ an Arabic word 
applied in the Nile Valley, and in the region of Nubia generally, both to this species 
and to C. pyrrhonotus. 
Cailliaud, writing in 1827, gave a short account of the different objects of natural 
history collected by himself on his travels in the Libyan Desert and in the Nile Valley
