The relative age was estimated from tooth wear if the skull was available (details to be published else- where). In addition, slides were taken of 128 specimens of A. pusillus and compared but not used in the final analysis because it was not possible to define any dif- ferences in colouration. The data basis for the analyses is given in Table 1. The maps given in Figures 3 to 5 are based exclusively on skins with coordinates of the col- lection locality. Statistics Relationships between the various colouration charac- ters and sex, age, and month of collection were checked with chi-square tests performed in SPSS In the re- ported results the number of specimens used for the and P values are given ( = not significant). Additionally, the percentage of cells with an expected frequency less than five (CEF<5) is given when it is higher than 0 analysis (n), the statistic {-£), degrees of freedom () and the minimum expected frequency (MEF) if it is less than 1. The same test was performed to check for statis- tically significant differences between geographically neighbouring populations. 3. COLOURATION CODING AND RESULTS Anomalurops beecrofti The most frequent colouration of A. beecrofti is a sil- very-grey on the back with a central stripe of golden brown from the neck over the larger part of the back. The ventral side is basically greyish or yellowish with an orange throat and chest. Colour variation in A. beecrofti can be defined by the extent of the golden brown stripe on the back and the amount of orange colour on the ventral side (Plate I)..
