title: The micromorphology of the apocrine glands of the intermandibular region of the steenbok (Raphicerus campestris).
abstract: The histological structure of the newly-discovered intermandibular glandular region in male and female steenbok is described. This region consists of enlarged sebaceous and apocrine glands which secrete a substance used for demarcating grazing territories and for marking females. Migratory lymphoid cells in the epithelium of the apocrine glands resemble Langerhans cells of the epidermis and forestomach epithelium but do not contain Langerhans cell granules. Cells, which are probably of lymphoid origin and resemble sebaceous gland cells, sometimes occur in the apocrine glands.
