Note (73) — BOOK V. (continued 2)

73. Cerastes, from κερας, a horn, is a serpent of one or two cubits in length, of a sandy colour in the body, and near the tail void of scales; upon its head something rises like horns, and the parts about the belly are covered with scales, orderly disposed, which as it creeps along makes a rustling noise like hissing.
