Four specimens, three males and one female (including 

 the type), taken togetlier on the same day, are very like one 

 another in all essential features, one only amono^st them 

 showing a rusty suffusion all over the body due to bleaching. 

 The constant absence of buffy colouring on the hands and 

 feet is very noticeable. The disproportionate breadth of the 

 skull is equally present in all four specimens. 



Some specimens from the adjoiriing Nyarsa-Tanganyrka 

 Plateau aj)pear to belong to this race.
