Figure 5. Line drawings by Richard Keane of various male members within the living Caprini. Taxonomy follows Grubb (1993), although see Valdez (1982). A, Capra pyrenaica (Spanish goat); B, Capra falconeri (markhor); C, Capra hircus (wild goat); D, Capra cylindricornis (tur); E, Capra ibex (ibex); F, Ammotragus lervia (aoudad); G, Pseudois nayaur (bharal); H, Hemitragus jemlahicus (Himalayan tahr); I, Ovis aries (=orientalis of Valdez 1982; urial); J, Ovis canadensis (Rocky Mountain bighorn); K, Ovis aries (=orientalis of Valdez 1982; mouflon); L, Ovis ammon (Marco Polo argali). Note the variation within the group, especially within the genus Capra. What is shown are the animals with their horn sheaths. Horn cores will not have the same length as the horn sheath; however, horn sheaths with torsion will have horn cores with torsion. Adapted from Schaller (1977, 1980).
