He relates that a variety occurs not only in this lake but also in the lake of the island Caraja, very slender in shape, and almost entirely ferruginous, without si:)ots, very unUlce the ordinary variety in ajipearance. These, he thinks, are hybrids, born in the lake, and the offspring of female Sahno callaris and of male S. sanguinolentus, of which species many are carried into these lakes, placed at an exceedingly elevated position, by a certain inundation of the sea, together with S. caUaris, and are both immediately seen to commence propsigation and soon afterwards to have their sexes in common, which is not without some semblance of ; It is quite evident that the notes given by PaUas above do not refer to a Charr, none of which migrate to the sea, as far as our present experience goes ; therefore Pallas appears to have joined the life-history of some fish to specimens of a distinct species. As re- gards the fish noticed by SteUer, no opinion can be off'ered until the localities mentioned are visited again, and their Salmonoids ex- amined. 17. Salmo leucomaenis. ?
