Galago allenii, Waterhouse, P. Z. S. 1837, p. 87- 



Fur dark, blackish brown ; forehead, rump, and base of tail grey ; 

 arms and legs reddish-washed ; nose-streak and underside of body 

 whitish ; tail black ; toes and fingers very slender, free ; ears mo- 

 derate. 



Length of hind foot 2" 1 0'". Skull (imperfect), length about 2" 2'", 

 breadth 1" 5'". 



Var. gabonmsis. Skull small, 2" 0"', width 1" 4i'". 



Hab. West Africa : Gaboon ; Fernando Po. 



There is a considerable difference in the two skulls of this species 

 which we have, though the skins resemble each other very closely, 

 so much so that it would not be easy to distinguish them as varieties. 

 The one from Fernando Po is larger, and the upper cutting teeth 

 form an arched series, and the grinders are very large and broad. 

 The one from the Gaboon is rather smaller in size, the upper cutting 

 teeth are in nearly the same straight transverse line, and the grinders 

 are scarcely three- fourths of the general width of those of the other 

 skull. Both skulls seem to have their perfect and permanent teeth. 

 Probably this may arise from the sex of the specimen ; but the sexes 

 are not marked, and there is no external character to distinguish 

 them. In a third and younger specimen the upper cutting teeth are 

 subequal, and placed one before the other ; so that this seems to be 

 the normal position of the teeth. 



** Tail clavate, hair of lower part adpressed, of end spreading ; 

 the fingers and toes broader, shorter; upper cutting teeth very 

 slender, in a straight cross Line.
