The correlation of series of two darkly-staining lines in the tooth cementum of tropical African mammals from areas of bimodal equatorial rainfall is briefly reviewed, and contrasted with the findings in southern Africa where bi-annual lines are claimed for areas of unimodal rainfall. A sample of African buffalo teeth from a unimodal rainfall area in southern Tanzania was examined and the conclusion reached that, in general, one dark line per year was formed. A miscellaneous selection of mainly known age animals was also examined with varied results. Anomalies in the apparent formation of cementum lines are discussed.
