THE GALA G OS, OR AFRICAN LEMURS 223 



This distinctive peculiarity of the ears is, of course, sufficient to enable us at 

 once to separate a galago from a mouse-lemur, and, indeed, from every other kind 

 of lemur. Zoologists are, however, by no means satisfied with distinguishing 

 animals merely by external characters ; and they have succeeded in finding a feature 

 in the teeth by which a galago differs markedly from a mouse-lemur, although, 

 unfortunately, this point of distinction can only be seen in a dried skull. If, how- 

 ever, we take the skull of a mouse-lemur, we shall find that while the last three- 

 upper teeth, or molars, have broad crowns and are alike, the tooth in advance of 

 these, which is the last premolar, has a smaller and simpler crown, of a triangular 

 shape. In a galago' s skull, on the contrary, this last upper premolar, although 

 slightly smaller than the molars, has a similarly shaped crown, broad on the inner 

 side, and nearly quadrangular in shape. 



The galagos are widely distributed over the " Dark Continent," one kind being 

 found as far south as Natal, while there are several on the western side and two 

 on the eastern. Like the mouse-lemurs, they are essentially nocturnal ; and are, of 

 course, confined to those regions where thick forest prevails. When not enjoying 

 their diurnal repose, they are lively and interesting. They subsist on a mixed diet, 

 including fruits, insects, and small birds and their eggs. Some of the smaller 

 species will readily devour locusts, and the peculiar leaf-like mantides, or praying 

 insects. When on the ground the galagos recall the lemurs of the indri group, in 

 that they generally sit in the upright position, and progress by a series of leaps or 

 hops. They usually have two or three young at a birth, and are stated to have 

 bred in captivity in Africa, although we are not aware whether they have done so 

 in Europe. Many of them, however, thrive well in our menageries, where some 

 have been represented by a considerable number of individuals. It is stated that 

 the galagos resemble the mouse-lemurs in building nests, which are situated in the 

 forked branches of trees ; but it is probable that this is only true of the smaller 

 species. They appear, however, to be peculiar in that several individuals will 

 inhabit the same nest, out of which they all rush when suddenly disturbed. The 

 total number of teeth, both in the galagos and the mouse-lemurs, is the same as in 

 the true lemurs. 



THE GREAT GALAGO {Galago crassicaudata*) 



With the exception of a closely-allied kind from the West Coast, the great, or 

 thick-tailed galago, of Mozambique and the Lower Zambesi valley, is the largest of 

 all the species. This animal, of which a figure is given on p. 224, is, in point of 

 size, about equal to a cat of average dimensions ; and, indeed, the peculiar manner 

 in which it carries its thick bushy tail high above its back is highly suggestive of a 

 pampered Persian cat. This bushy tail is about one-fourth longer than the head 

 and body. The great galago belongs to a group of three or four species, in which 

 the ears are unusually long, and the muzzle is considerably elongated, while the 

 feet are comparatively broad and short, and the fingers and toes have broad 

 disk-like expansions at their extremities. The color of the fur is a uniform dark 

 brown.
