Abstract
G-banded karyotypes are compared in Lemur mongoz, L. f. fulvus, L. catta, L. macaco, L. variegatus, Hapalemur griseus and Lepilemur mustelinus. The occurrence of remarkable homology of chromosome- and arm-pairs in the Lemur species suggests their close relationship. H. griseus is not far divergent from the Lemur species. L. mustelinus is of a distant relative to Lemur and Hapalemur.
