SHORE FISHES OF THE TEMPERATE NORTH PACIFIC. This fauna shows a great affinity to that of the temperate North Atlantic, not only in including a considerable proportion of identical genera, and even of species, but also in having its constituent parts similarly distributed. However, our knowledge of the ichthyology of this fauna is by no means complete. Very few collections have been made in Northern Japan, and on the coasts farther north of it; and, again, the ichthyology of the coasts of Southern California is but little known. Southern Japan has been well searched, but very little attention has been paid to the extent of the northward range of the species. In collections made by Mr. Swinhoe at Chefoo, in lat. 37° N., the proportions of temperate and tropical fishes were found to be about equal. Thus, the details of the distribution of the fishes of these shores have still to be worked out; nevertheless, three divisions may be recognised which, for the present, may be defined as follows:-- 1. The fishes of the north-western shores, to about 37° lat. N., including the corresponding northern parts of Japan--_Kamtschatkan_ district; this corresponds to the British district of the Atlantic. 2. The fishes of Southern Japan and the corresponding shores of the continent of Asia, between 37° and 30° lat. N.--_Japanese_ district, which corresponds to the Mediterranean. 3. The fishes of the eastern shores southwards to the latitude of San Francisco--_Californian_ district; this corresponds to the North American district of the Atlantic. Too little is known of the shore fishes of the coasts between San Francisco and the tropic to enable us to treat of it as a separate division. The Shore fishes of the North Pacific generally are composed of the following elements:-- _a._ Arctic forms which extend into the Arctic Ocean, and the majority of which are also found in the British district. _b._ Peculiar forms limited to the North Pacific, like the _Heterolepidina_, _Embiotocidæ_, and certain Cottoid and Blennioid genera. _c._ Forms identical with fishes of the Mediterranean. _d._ Peculiar forms limited to the southern parts of Japan. _e._ Tropical forms which have entered the North Pacific from the south. * * * * *
