Note 69 — THE NOCTURNAL LIFE OF ANIMALS IN THE PRIMEVAL FOREST.
Henry G. (Henry George) Bohn translation
p. 199.—“The fresh-water dolphin.”
These are not sea dolphins, which, like some species of Pleuronectes (flat fish which invariably have both eyes on one side of the body), ascend the rivers to a great distance, as, 203for instance, the Limande (Pleuronectes Limanda), which is found as far inland as Orleans. Some forms of sea fish, as the dolphin and skate (Raia), are met with in the great rivers of both continents. The fresh-water dolphin of the Apure and the Orinoco differs specifically from the Delphinus gangeticus as well as from all sea dolphins.[IL]
