 undescribed species. The first was characterised as

Obs. This specimen, which has four incisors in the upper jaw. and 

 six in the lower, is about the same size as the Galago Senegalensis, but 

 may be readily distinguished from that species by the greater size 

 of the ears, (the length of which is equal to the distance between 

 the tip of the muzzle and the base of the ear,) and the great length 

 of the fingers and toes. In the colouring there is also a difference, 

 G. Senegalensis being grey, washed with yellow, whereas G. Alleni is 

 of a deep slate grey, all the hairs of the upper parts being of a rusty 

 yellow at the apex, or, as on the fore legs, rusty at the tip. The 

 under parts of the body are of a paler hue than the upper, the hairs 

 being of a dirty yellow colour at the tip ; but like those of the upper 

 parts, they are of a slate grey for the greater portion of their length : 

 on the throat and chin each hair is whitish at the apex. The hairs 

 covering the feet are of a deep brown colour. The tail is dusky 

 brown. 



The animal here described was presented to the Zoological So- 

 ciety by Lieut. Wm. AUen, R.N., Corres. Memb.
