In ordinary Osseous Fishes, figs. 181,185, the exterior white fibres of the optic lobes converge to their under and anterior part, to form the chief part of the origin of the optic nerves ; but a portion of the origin may be traced through the septum opticum to the cerebellum; and in the Eel, the Garpike, and the Lump-fish, a portion may be traced to the hypoaria: in the Cod, fig. 185, and.
