1J8 DR. J. E. GRAY ON THE SPECIES OF I.KMVROinS. [April 21, 



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, 

 and I think they may easily be distinguished by the length and colour 

 of the tail. G. maholi and G. senegalensis have the tail only rather 

 longer (not more than one-fifth) than the body and head. In G. 

 maholi the tail is rather dark, but grey ; in G. senec/ulensis 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.
