. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. Anja C. Schunke & Rainer Hutterer: Geographie Patterns of Coat C olouration in Anomalurops and Anomalurus 179 In N- and C-Democratic Republic of Congo, W-Angola, Uganda and Kenya specimens of A. derbianus arc re- markably uniform except for a tendency towards ears of the same colour as the rest of the head from NE- Democratic Republic of Congo to Kenya. Finally, one borderline separates specimens from fi-Angola, S- Democratic Republic of Congo, Zambia, and Tanzania from the rest of the distribution area. This is best shown by the frequencies of the ear colouration, but it is also parallelled by the occurrence of silvery specimens which are restricted to this southern area. Differences are less pronounced for the ventral and throat colouration, which is partly due to the smaller data set. This caused problems for a reliable calculation of statistically significant differences. However, in Tan- zania specimens from the Usambara Mountains show mainly yellow and yellow mixed with grey underparts. while those from further south are whitish or greyish without yellow. Anomal urns pelii This species is generally black with while margin ol the patagia, a white tail and a ventral colouralmn rang- ing from white to blackish grey. White markings can also be completely absent. The variation in A. pelii is mainly defined by the relative portions of black and white (Plate III)..
