GALAGOS.

Allen’s Galago (Galago alleni). 
With the West African species we come to the first representative of a group 
distinguished from the preceding one by the more rounded head, shorter muzzle, 
and larger eyes, as well by the longer and more slender form of the foot. 
Allen’s galago is found at Fernando Po and the Gabun, and is characterised 
by the tail being thick and bushy, and also by the extreme length and slenderness 
of its fingers and toes. The prevailing colour of the fur is blackish-brown, with 
the forehead, rump, and the root of the tail grey, a tinge of red is on the limbs, the 
tail is black, and a streak on the nose and all the under-parts are whitish. 
If we examine the skull of this species it will be noticed that the last 
molar tooth on each side of the upper jaw is nearly equal in size to the tooth in 
advance of it. This will be found an important point of distinction between 
Allen’s galago and all the remaining species, in which the last upper molar is much 
smaller than the tooth in front of it. 
The Senegal Galago (Galago senegalensis). 
The longest-known of all the galagos is the Senegal galago. It was originally 
described so far back as the year 1796, from specimens brought from Senegambia, 
which may be regarded as its headquarters. Subsequent discoveries have, however, 
shown that a galago exists on the east side of Africa to the south of the Sudan, 
which, although described as a distinct species under the name of the Sennaar 
galago ( G . sennariensis), is so closely allied to the Senegal galago that it may 
probably be regarded as a mere local variety or race. Indeed, it is probable 
that when we are fully acquainted with the zoology of the vast stretch of country 
lying to the south of the Sahara desert, it will be found that this galago extends 
right across Africa. 
In addition to the distinctive character of the upper molar teeth already 
mentioned, the Senegal species has certain marked external features by which it 
differs from Allen’s galago. Thus, in the tail the hairs near the root are pressed 
down, only those nearer the end spreading out on all sides, so that the whole tail 
assumes a somewhat club-like form. Then, again, the fingers and toes are consider¬ 
ably thicker and shorter than in Allen’s galago. In colour the typical Senegal 
galago is grey, with the under-parts and a streak on the nose white, and the tail, 
hands, and feet blackish-brown. The Sennaar race appears to have a rather bluer 
tinge to the fur, with a darker face, and black rings round the eyes; while the 
tail is described as being relatively longer. It is of comparatively small size, 
and appears to be common in the forests of Senegal, and in those on the Blue 
Nile in Kordofan, and the White Nile in Sennaar. Its chief food consists of 
various kinds of insects; but it is stated that it will also eat the gum of various 
kinds of acacia, which we have already noticed as forming part of the diet of 
the baboons of the Sudan. Its habits are said to be similar to those of the other 
species. 
In South Africa the Senegal galago is represented by a species so nearly allied 
to it that some writers have thought that the two forms are only varieties. This
