428 GEOGRAPHICAL ZOOLOGY. [part iv.
They are divided by Dr. Giinther into four groups. The
Heterolepidina (comprising 4 genera and 12 species) are con-
fined to the North Pacific. The Scorpsenina (23 genera 113
species) have an almost universal distribution, but the genera
are each restricted to one or other of the great oceans. Sehastes
has occurred on the English coast. The Cottina (28 genera 110
species) have also a universal distribution ; the numerous species
of Gottus are found either in the seas or fresh waters of Europe
and North America ; four species are British, as well as seven
species of the wide-spread genus Trigla. Ptyonotus (1 sp.) is
confined to Lake Ontario. The Cataphracti (5 genera, 23 species)
have also a wide range ; one genus, Ayonus, is found in the
British seas, and also in Kamschatka and on the coast of Chili.
Peristethus is also British.
Family 11.—TEACHINID^. (24 Genera, 90 Species.)
" Carnivorous marine fishes, with elongate bodies, living at the
bottom, near the shore."
Distribution.—Almost or quite universal.
Trachinus is a British genus. A species of Aphritis inhabits
the fresh waters of Tasmania, while its two allies are found on
the coasts of Patagonia.
Family 12. SCI^NID^. (13 Genera, 102 Species.)
" Marine or fresh -water fishes, with compressed and rather
elongate bodies, covered with toothed scales."
Distribution.—Temperate and tropical regions, but absent
I'rom Australia.
Larimus is found in the Atlantic, and in African and American
rivers. Corvina, Scicena, and Otilothus are also marine and fresh-
water, both in the Atlantic and Pacific. The other genera are of
small extent and more restricted range. Umhrina and Scicena
have occurred in British seas.
