The structure of the capsule, zona glomerulosa and zona fasciculata of the African elephant (Loxodonta africana) is described. The gland is surrounded by a connective tissue capsule from which connective tissue trabeculae extend towards the medulla. The arrangement of the cells in the zona glomerulosa and the zona fasciculata are similar to that described for other mammals. Two types of cells are found in the zona glomerulosa and three types in the zona fasciculata. Organelles in these two zones are as described for other cells that secrete steroids. Unidentified structures were observed in the zona fasciculata
