"Being a sizeable tortoise with a massy shell of broad circumference. Customarily living in the deep places of the earth - caves and like - save during the Rains, when they are known to emerge and forage in the vicinity of water. Tortoises, newly spawned, are wrapped in a thick shell, protecting them after the fashion of an egg. Upon their growing, the legs and feet break through the shell, this being the adult form, whereafter they continue to grow until such growth is arrested by illness or incident."
