GEOGRAPHICAL ZOOLOGY. 
[part IV. 
They are divided by Dr. Gunther into four groups. The 
Heterolepidina (comprising 4 genera and 12 species) are con- 
fined to the North Pacific. The Scorpaenina (23 genera 113 
species) have an almost universal distribution, but the genera 
are each restricted to one or other of the great oceans. Sebastes 
has occurred on the English coast. The Cottina (28 genera 110 
species) have also a universal distribution ; the numerous species 
of Cottus 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, Agonus, is found in the 
British seas, and also in Kamscliatka and on the coast of Chili, 
Peristethus is also British. 
Family 11.— TKACHINID^E. (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. SCIiENIDiE; (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 
from Australia. 
Zarimus is found in the Atlantic, and in African and American 
rivers. Corvina, Scimna, and Otilotlms are also marine and fresh- 
water, both in the Atlantic and Pacific. The other genera are of 
small extent and more restricted range. Umbrina and Scicena 
have occurred in British seas.
