Note 1981 — BOOK VIII. THE NATURE OF THE TERRESTRIAL ANIMALS. (continued 2)
John Bostock translation
“Tectæ.” The context shows that this means covered with skins or a woollen girth, probably on account of their delicate nature, while the common sheep of husbandry, or the “colonic” sheep, were able to endure the rigour of the weather without any such protection.
