Domning (DPD); H. N. Hoeck (HNH); J. Shoshani (JS). COMMENT: Hyracidae Gray, 1821 , is a group name based on Hyrax Hermann, 1783 . The number of valid species is uncertain; see Bothma, 1971 , Part 12:1-8; Corbet, 1979 , Bull. Br. Mus. (Nat. Hist.) Zool., 36:251-259. Revised by Hahn, 1934 , Z. Saugetierk., 9: 207. Also see Allen, 1939 , A Checklist of African Mammals; Roberts, 1951 , The Mammals of South Africa ; Meyer, 1978 , in Maglio and Cooke. The generic definitions are also controversial; Roche, 1972 , Mammalia , 36:22-49 retained only Procavia and Dendrohyrax but Hoeck, 1978 , Carnegie Mus. Nat. Hist., 6: 146-151 retained Procavia , Heterohyrax , and Dendrohyrax as separate genera, and is followed here. ISIS NUMBER: 5301416001000000000.
