THE FOUR-HORNED TRUNK FISH.
(Ostracion quadricornis.)
These singular fishes are distinguished from most others by the bony covering which envelopes them. The head and body are covered with plates of bone, forming an inflexible cuirass, and leaving exposed only the tail, fins, mouth, and a portion of the gill opening. They have no ventral fins, and the dorsal and anal are placed far back. Their liver is large, and abounds with oil. The Trunk-fish is a native of the Indian and American seas. Some of the species are considered excellent eating.
