Note 53 — Chapter V
Reading edition
The three species of real turtle belonged two to the genus Chelone and one to Thallassochelys, viz. the Hawksbill Turtle, the shell of which is the tortoiseshell of commerce; the Green Turtle, which makes turtle soup, and is delicious to eat; and the musky-smelling useless Loggerhead Turtle. The fourth kind was the quite unrelated Leathery Turtle (Sphargis), which grows to a great size, 7 to 8 feet long.
