is no trace on either side of the small anterior lower premolar, 

 a peculiarity not occurring in any other specimen of the

 breadth 23 ; breadth of palate across outer corners of m 1 35*5 ; 

 front of canine to back of »* a 41 ; greatest horizontal diameter 

 of p 4 10, m 2 8-3, p A 8-2, m 1 8'9, m 2 7'5.

The above division into "subspecies" is, of course, only 

 provisional, until such time as sufficient material is available 

 for the true relations of the different forms to be made out. 

 Probably the north-eastern type, paler in colour, rather 

 smaller, and with very small m 2 , should in any case be looked 

 upon as a distinct species. Whether it overlaps the larger 

 and darker animal remains to be seen.

In his classical paper on the mammals of Angola, Prof, du 

 Bocage stated that the squirrels he referred to Sciurus congicus, 

 Kuhl, presented several different types of coloration, and I 

 am inclined to think that these are so different as to deserve 

 recognition by name. For the moment I shall treat them as 

 subspecies of congicus, though I think it probable that when
