Note 2563 — BOOK IX. THE NATURAL HISTORY OF FISHES.

Aristotle, Hist. Anim. B. iv. c. 2, has a somewhat similar passage. “The kinds of crabs are numerous, and not easily to be enumerated. First, there are those known as maiæ, then the paguri, which are also called ‘heracleotici;’ and, after them, the river crabs. There are others, again, of a smaller size, and which, for the most part, are known by no name in particular.”
