178 NORTHERN ZOOLOGY. 



The Salmo fontinalis is probably what is called in the narrative of Lewis and 

 Clark's Journey to the Pacific, the mountain, or speckled trout of the United 

 States. Another species, which inhabits the upper waters of the Missouri and 

 Columbia, is thus described iu the same work. " We caught in the Falls half a 

 dozen trout resembling in form and the position of the fins, the mountain, or 

 speckled trout of the United States, except that the specks of the former are of a 

 deep black colour, while those of the latter are of a red or gold colour : they have 

 long sharp teeth on the palate and tongue, and generally a small speck of red on 

 each side, behind the front ventral fins ; the flesh is of a pale yellowish red, or, 

 when in good order, of a rose-coloured red. We never saw this fish below the 

 mountains, but from the transparency and coldness of the Kooskooskee, we should 

 not doubt of its existence in that stream, as low as its junction with the south-east 

 branch of the Columbia. It is not so abundant in the Columbia as in the Mis- 

 souri." (i., p. 358, and iii., 601.) 



I am unable to decide from Fabricius's account of the Greenland trouts, whether 

 they are identical with any of those described above, or whether they ought to be 

 reckoned as distinct species. His S. carpio, named Eekallook, Kebleriksoak, 

 Satooack, and Sardhoak, by the natives, is probably S. Hoodii. It is an inhabi- 

 tant of the rivers, lakes, estuaries and bays of Greenland, and feeds upon caplin, 

 herrings, sticklebacks, small crabs, worms, and spawn of fishes. It is named Lax, 

 or the Salmon, in the histories of Greenland, and is supposed by Fabricius to be 

 the same with the Kundsha of Pallas, a trout which abounds in the gulfs of the 

 Icy Sea and of Kamtschatka, but is said not to ascend rivers. 



Another Greenland trout with an orange belly, named by the natives Eekallook 

 and Iviksarok, was considered by Fabricius to be the same species with his S. 

 carpio, but he changed his opinion, in some degree, after leaving the country, and 

 referred it to the S. alpinus of Linnaeus, when he had no longer an opportunity 

 of comparing it with carpio. It congregates with the preceding, and may possibly 

 be the trout I have described under the specific name of S. nitidus, the tawny- 

 orange colour of the belly in both being confined to the spawning season. 



The /S. stagnalis (Fauna Grcenl, p. 175) agrees best with our S. alipes. It 

 inhabits alpine waters, and never descends to the sea. It is named Eekallookak.
