Note 2570 — BOOK IX. THE NATURAL HISTORY OF FISHES.
John Bostock translation
Aristotle, Cuvier observes, states the carcini, or crabs, have no tail, the fact being that the tail is extremely small, and is concealed, as it were, in a furrow in the under part of the body. The cray-fish, on the other hand, has a large and broad tail.
