The Cavicomia comprise the three families of the Antilopida, Ovidce, and Bovidce. The Antelopes form an extremely large section, with very many species. They are characterised by their slender deer-like form, their long and slender legs, and their simple cylindrical annulated or twisted horns, which are sometimes confined to the males, but often occur in the females as well (fig. 220). The Antelopes must on no account be con- founded with the true Deer, to which they present many points of similarity. The structure of the horns, however, is quite suffi- cient to distinguish them. The Antelopes are further distin- guished by rarely having a beard or dew-lap, and by the general possession of '.' inguinal pores'' and "lachrymal ;. Fig. aso.—Head of the Koodoo (Slrejisiceros Koodoo). The inguinal pores are the apertures of ;;wo involutions of the integument of the groin, secreting a viscous substance, the use of which is unknown. The lachrymal sinuses, or " tearpits," have already been mentioned as occurring in the Cervidce, and are not found in any of the Cavicomia except the Antelopes. Each consists of a sebaceous sac placed beneath the eye, and secreting a yellowish waxy substance. The function of these glands is uncertain, but it is probably sexual. The Antelopes are especially numerous, both in individuals and in species, in Africa, in which country they appear to take the place of the true Deer (only one species of Deer being indigenous to Africa). Amongst the better-known African species of Ante- lopes are the Springbok, Hartebeest, Gnu, Eland, and Gazelle. The only European Antelope is the Chamois {Riiplcapra ira-.
