The European species is Balistes capriscus, a common inhabitant of the Mediterranean, and occasionally met with on the southern coasts of England. It grows to the length of 2 feet. B. aculeatus, a native of the Indian and American seas, as well as of the Red Sea, is sometimes 12 or 14 inches long. Another is a monacanthine fish, Alutera schæpfi, with a single dorsal spine, a moderate abdominal flap not extended beyond the pelvic spine, and of a dull-greenish color mottled with a darker hue. It is abundant along the southern coast of the United States.
