. The regression equations of both recent populations differ from that of the fossil one at P = 30 %. Thus statistically this is not a significant difference too. Fora final decision a bigger than the available material is needed. Another scatter diagram (Fig. 3.) shows that the heights of mandible under M^ and behind M3 are differently proportionated in Rh. lissiensis than in Rh

. euryale

. The mandible is rather high under M^ in Rh. euryale, whilst comparatively low in Rh. lissiensis. One could infer even a reverse ratio, not yet understood, beetwen the
