Note 2288 — BOOK IX. THE NATURAL HISTORY OF FISHES.

Cuvier remarks, that there is some confusion here between an animal of the dolphin kind, and another of the genus Squalus. He suggests that the Delphinus tursio of Linnæus (our porpoise) is meant; but then there would be no ground for comparing its teeth with those of the dog-fish or shark. He remarks also, that Athenæus, B. vii. p. 310, speaks of pieces of salted flesh from the dog-fish, as being called by the name of tursio.
