Population systematics of the gorilla


  • (With 4 figures in the text)


The systematics of the gorilla are reviewed in the light of abundant new material, examined with the aid of techniques of multivariate analysis. Defects are pointed out in the usually accepted view that there are two clear-cut subspecies (G. g. gorilla and G. g. beringei); the existence of morphological intergradation is shown, and an intermediate subspecies, G. g. grueri, is recognized in addition.
