Hermann, Tab. Affinit. Anim. p. 115 (1783). It has recently been proposed to substitute the earlier name Procavia in lieu of Hyrax. The anatomy of Hyrax was first described by Pallas (Spicilegia Zoologica). Besides minor memoirs, two detailed accounts of its structure have appeared—one by Brandt, in Mém. Acad. Nat. Scien. St. Pétersbourg, 7ⁱᵉᵐᵉ sér. vol. xiv. No. 2, 1869; and another by George, in Annales des Sciences Naturelles, 6ⁱᵉᵐᵉ sér. tom. i. 1874, in which references to all the previous literature will be found. The mechanism by which the sole of the foot is enabled to adhere to smooth surfaces is fully described by G. E. Dobson, Proc. Zool. Soc. 1876, p. 526.
