gilt-head

To give another instance: upon examining the fins of a fish to me unknown, I find them prickly; I then look for the situation of the ventral fins, I find them entirely wanting; this then must be a prickly-finned apodal fish. Of this kind there are but three; and, by comparing the fish with the description, I find it either of the trichurus kind, the sword-fish, or the gilt-head.
