7. GALAGO. 85 
The upper front cutting-teeth are very slender, longer and more 
produced, the upper grinders are broader and squarer, and the 
hinder one is more triangular than in G. maholi. 
There are three specimens of this species in the Museum, unfor- 
tunately not in a good condition ; but they all decidedly differ from 
G. maholi, especially in the length of the toes, and in the fingers 
and toes being more slender. These three species are very similar, 
but I think they may easily be distinguished by the length and 
colour of the tail. G. maholi and G. senegalensis have the tail 
not more than one-fifth as long again as the body and head. In G. 
maholi the tail is rather dark, but grey; in G. senegalensis it is much 
darker, being blackish brown. In G. sennariensis the tail is much 
longer than the body and head, and black. There seems also to be 
some difference, although difficult to describe, in the proportion of 
the ears and the head.
