Then after this there are boaces and Smarides, anchovies, also cammori. And Sophron, in his Female Farces, mentions them. But they are a species of squill, and this name was given them by the Romans. 76. There is also a fish called the carcharias. Numenius of Heraclea, in his Art of Fishing, says— [Sidenote: FISH.] At times you may too a carcharias catch, At times a psamathis who loves the surf. And Sophron, in his Tunny-hunter, says, "But if your stomach happens to have swallowed a carcharias." But Nicander the Colophonian, in his essay on Dialects, says that the carcharias is also called the lamias and the squill. 77. There is also the cestreus. Icesius says, "Of the fish which are called by one general name of leucisci there are many sorts; for some are called cephali, and some cestres, and some chellones, and some myxini. But the cephali are the best both in flavour and juiciness; the next to them are those called the cestres; the myxini are inferior to either. But the worst of all are the chellones, which are called bacchi; and they are all full of wholesome juice, not very nutritious, but very digestible." And Dorion, in his essay on Fish, mentions the sea cestreus, but does not approve of the river one. And the sea cestreus he subdivides into two species—the cephalus and the nestis. But the cestreus, which is like the sea-urchin about the head, he calls sphondylus. And he says "that the cephalinus differs from the cephalus, and that this last is also called the blepsias." But Aristotle says, in the fifth book of his treatise on the Parts of Animals, "But of the different kinds of cestreus, the chellones begin to be pregnant in the month Poseideon; so does the sargus and the fish called the myxus; and so does the cephalus: and they go thirty days with young. But some of the cestres are not generated by copulation, but are produced by the slime and the sand."
