In several papers, dealing with the skeleton, the growth, and the body proportions of primates, the author (1927, 1930, 1933) has been able t demonstrate tentatively a considerable variety of apparent differences be-tween the mountain gorilla and the West-African lowland gorilla. In view of the very marked variability of gorillas and on account of the scarcity of avail-able material, particularly of the mountain gorilla, it was not possible to claim that the conditions observed necessarily represent typical and generally pre vailing differences. It is the purpose of the present study to collect briefly the more significant differences recorded in previous publications and to tes the validity of these differences by means of new observations on additiona material.
