. Bonner zoologische Monographien. Zoology. 34 Canonical Discriminant Analyses The principal results of the first canonical discriminant analysis for the xanrhina species-group is the discrimination of three major aggregations along the first two axes (Fig. 11). The first aggregation, to the right, represents the western Anatohan Vipera xanthina populations together with the Iranian V. wagneri (16). The middle group represents the Lebanese V. bornmuelleri and the third group (13), to the left, is V. hulgardaghica, the endemic population of the Bulgar Dagh mountains in south central Fi

Population numbers refer to Fig. 1 and the text. Populations of Vipera xanthina (to the right) and of bornmuelleri (in the middle) are connected by basal lines. The single available Iranian specimen of V. wagneri is closest to the V. xanthina aggregation. Ahhough widely separated geographically, the single specimen known seems to be phenetically similar, indicating a close relationship to V. xanthina although it shares many morphological characters with V. bornmuelleri. Within the middle group of bornmuelleri sample means, two phenetically distinct aggregations are apparent along the third axis with one composed solely of Mt. Hermon vipers (14) and the other entirely of Mt. Liban vipers (15). This separation of the two bornmuelleri populations is striking but not totally unexpected, as they also are geographically isolated, restricted to high altitudes in the two mountain chains mentioned above, and separated by the deep Bekaa valley in Lebanon. The canonical discriminant analysis of the raddei species-group (Fig. 12) also results in a discrimination of four major aggregations; they are, from right to left, north.
