. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. remaining countries (Ghana, Ivory Coast, Cameroon, Liberia and Togo) indicates, that if a subspecific difference should occur, it cannot be found between West and East Africa. The large overlap between Cameroon and all other groups, furthermore indicates that the differences with Central Africa are also small. Similar results are obtained from analyses on all the skull and the external measurements. Therefore, one can conclude that there is no justification for subdivision into subspecies. In the small size group, the situation is more complicated. As a result of the vast distribution area, many different forms were described, of which the East African aurita is discussed more thoroughly. A first principal components analysis on the tooth measurements of 46 specimens from East Africa is represented by figure 3. For this analysis, 24 specimens from Kenya ("1", including the holotype of aurita "Tl"), 12 specimens from Tanzania ("2") and 10 specimens from Uganda ("3") were used. All five original variables are cor- related positively with the first principal component (P. — from for c-c to for Mand), indicating that the first P. C. is a good indicator for the size of the animals. From the graph one can see that the material from Tanzania ("2") can easily be divided into two groups. In the Kenyan material ("1"), where the separation is less clear, the specimens on the extreme left represent animals from Kilifi and Tana river, which are also found in the cluster on the right, indicating sympatric occurrence of two different forms. On the other hand, the specimens from Uganda are very.
