Note 2318 — BOOK IX. THE NATURAL HISTORY OF FISHES.

Cuvier remarks, that it is by no means clear what fish is meant by this name, which is only found here and once in Hesychius, who calls it κητώδης, “of the large kind.” Rondelet, in his account of river fish, suggests that “exos” is the proper reading, and that under this name is meant a species of sturgeon. Gesner asks if it might not possibly have been the “brochet;” but, as Cuvier says, that fish was well-known to the Romans under the name of “lucius” [our pike], and it is not sufficiently large for Pliny to compare it to the wels or the attilus, and for Hesychius to have enumerated it among the “large” fishes. It is in accordance, however, with this suggestion of Gesner that the pike genus bears the name of “esox” in modern Natural History.
