Note 2508 — BOOK IX. THE NATURAL HISTORY OF FISHES.

This name, Cuvier observes, is still common on the coasts of the Mediterranean, to two kinds of flying fish, the Dactylopterus, or Trigla volitans of Linnæus, and the Exocœtus volitans of Linnæus. It is to the first, he thinks, that the ancients more especially gave the name of swallow, although Salvianus and Belon are of the contrary opinion. Oppian, Halieut. B. ii. ll. 457-461, ranks the sea-swallow with the scorpion, the dragon, and other fish the spines of which produce mortal wounds, and Ælian, B. ii. c. 5, states to the same effect. But the exocœtus has no spines, while the dactylopterus has terrible ones on its præopercules. Speusippus also, as quoted in Athenæus, B. vii., gives no less decisive testimony, in saying that the sea-cuckoo, the trigla, and the sea-swallow, have a strong resemblance to each other; the fact being that the dactylopterus is of the same genus as the sea-cuckoo, the Trigla cuculus of Linnæus.
