Other stones, again, derive their names from various animals. Carcinias[1] is so called from the colour of the sea-crab; echitis,[2] from the colour of the viper; scorpitis,[3] from either the colour or the shape of the scorpion; scaritis, from the fish called scarus;[4] triglitis, from the sur-mullet;[5] ægophthalmos, from the eye of the goat; hyophthalmos, from the eye of the swine; geranitis, from the neck of the crane; hieracitis, from the neck of the hawk; and aëtitis, from the colour of the whitetailed eagle. Myrmecitis[6] presents the appearance of an ant crawling within, and cantharias,[7] of a scarabæus. Lycophthalmos[8] is a stone of four different colours; on the exterior it is ruddy and blood-red, and within it is black, surrounded with a line of white, closely resembling the eye of the wolf in every respect. Taos[9] is a stone with colours like those of the peacock. Timictonia, I find, is the name of a stone, like the asp in colour.
