THE GALAGOS, OR AFRICAN LEMURS 227 



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 con- 

 siderably thicker and shorter than in Allen's galago. In color the typical Senegal 

 galago is gray, 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 

 southern form is the Maholi galago (G. maholi}, which is a distinctly inland species 

 found as far south as Natal, and also met with in Nyasaland and the adjacent 

 districts. A galago from the neighborhood of Titi, some distance up the Zambesi, 

 has been identified with the Sennaar variety of the Senegal galago, but it would ap- 

 pear more probable that it is one of these. The prevailing color is brownish, 

 or yellowish gray, becoming darker on the back, and still more so on the tail ; while 

 a broad streak on the nose, the cheeks, and the throat are white, and the inner sur- 

 faces of the limbs and the under parts are whitish, with a faint tinge of yellow. In 

 the male specimen in the British Museum brought home by the late Sir Andrew 

 Smith, the original describer of this animal, the fur surrounding the eyes is. 

 of the same color as that on the other parts of the head. In other examples in 

 the national collection there are, however, dark rings round the eyes. This variabil- 

 ity shows that we must not regard the presence or absence of such rings as in- 

 dicating a specific distinction between the Senegal and Sennaar galagos. 



DEMIDOFP'S GALAGO {Galago demidoffi) 



The smallest and the last of these lemurs that we shall mention is Demidoff's 

 galago, from the west coast of Africa. This animal differs from the two species 

 just considered by its more slender and cylindrical tail and smaller ears. The 

 length of the head and body is five inches, and that of the tail seven and one-half. 

 The general color is brown, darker on the sides of the face ; the white streak on 

 the nose being narrow, and the chin, throat, and under parts of a reddish gray 

 color. The so-called G. murinus, from Old Calabar, is probably identical with this 

 species.
