Characters. Head round ; muzzle pointed ; eyes very large ; 

 ears also very large, long, nude, and membranaceous ; ringers 

 and toes very long, slender, and fine. Tail thick, round, and 

 longer than the body ; ankle-bones elongated. Length of body, 

 8J^ inches; tail, 10 inches. Head brownish-grey; a narrow black 

 ring round the eyes ; a streak from the forehead down the nose 

 whitish ; back greyish-brown, washed (sometimes markedly) with 

 rufous on the upper back, fading out towards the root of the 

 tail; the latter black or greyish-black. Outside of arms and 

 legs washed with rufous, sometimes with a white spot on the 

 shoulder-joint and over the groin; posterior aspect of legs sooty- 

 black ; cheeks, sides of nose, entire under surface, and inner 

 side of limbs creamy-white with a rufous-washed bar across the 

 chest. Muzzle shorter than the diameter of eye-socket. Incisors 

 seen from the side, more or less hidden by the canines; anterior 

 upper pre-molar very canine-like, relatively much produced lon- 

 gitudinally, with an interval between the anterior and median 

 pre-molars ; posterior upper pre-molar four-cusped, and with an 

 intermediate cusp on the oblique ridge ; posterior upper molar 

 almost equal in size to the median one. 



Distribution. This species has been recorded from the 

 Gaboon, in West Africa, and from Fernando Po, whence it was 

 first obtained by Captain Allen, R.N., in 1837. 



Habits. Although little or nothing has been recorded of its 

 habits, it is unlikely that they differ much from those of the 

 species already known.
