. On the anatomy of vertebrates. Vertebrates; Anatomy, Comparative; 1866. Brain ; ;ldosteus BraiQ; Amblj'opsi3 magnllled. Brain; Eel. CCii. greatly In difFcreiit bony fishes ; it is very small in tlie lazy Lnmp- fish, and extremely large in the active and "\varm-l:>h)oded Tunny, where, also, its surface shows transverse j^-roovings. The cerebellum is unsymmetrically placed in the Pike and some Flat-fish {Plevronectida), and is unsymmetrically shaped in the Sharks : it presents a longitudinal groove in the Diodon, and a pos- terior notch in the Herrino-: a transverse notch di- vides it into an anterior and posterior lobe in the Lophius : it bears a crucial depression in the Skate. The cerebellum presents in many fishes a small cavity or fossa at its under part, continued from the fourth ventricle, fig. 178, c: it is solid in the Tench, the Garpike, and the common Eel: some grey matter is usually found in its interior, with feeble indications of vphite stria3; but there is no ' arbor vitas,' except in the Tunny and Sharks. The posterior ' crura cerebelli' are formed by the posterior pyramids, fig. 172, d, with part of the restlform tracts, ib. c; vertical fibres from the sides of the cerebellum continue to attach it to the sides of the restiform or trige- minal lobes, and some of these are continued as arciform fila- ments upon the under surface of the medulla oblongata: they answer to the ' crura cerebelli ad j)ontem ' of Mammalia ; but, as T 2 ]Jra1n and portion of spinal marrow of Cliub {LcitclHcus) Scctiou of Biaiii, Carp.
