New Caledonia as follows : “The vltai of the New Caledonia tribes differs from the last* in 
the scales being firmer, duller, and rather smaller, and the body more thickly and generally 
covered with black spots, which extend well down the sides. The spots on the dorsal and tail are 
also more regular and conspicuous, and the teeth are stronger, especially those on the palate 
bones ; a flexuose row on the vomer does not extend quite so far back as the palatine teeth. 
The vltai is most probably the Salrno clarlcii , (p. 225,) and also the dark salmon-trout of Lewis 
and Clark, noticed in page 163.” 
The mylciss of Kamtschatka referred to by Richardson is the S. purpuratus of Pallas. From 
the abundance of red and purplish markings of this fish—marks by no means strongly displayed 
by Dr. Girard’s S. clarkii , even when that fish is in bad condition—we certainly cannot consider 
the latter to be the mykiss , or that the S clarkii of Girard is that of Richardson. 
The Salmo clarkii of Richardson is probably one of the autumnal species of anadromous 
salmon which, not feeding in fresh water, become, when exhausted, marked with patches of 
red. No specimens have been obtained in any of the recent collections.

Sp. Cel— Body sub-fusiform ; head well developed, forming the fifth of the total length. Maxillary slightly bent, extend¬ 
ing to a vertical line drawn inwardly to the posterior rim of the orbit. Jaws equal. Anterior margin of dorsal fin a little nearer 
the extremity of the snout than the insertion of the caudal fin. Back brownish grey ; upper surface of head blackish grey ; 
sides silvery grey; fins ash grey ; dorsal and caudal spotted. Upper regions of head and body studded with irregular black 
spots or specks. Tail emarginate.

I obtained this species at the Cath-la-pootl river, August 2, 1853, and am indebted for it 
to the skill of Captain McClellan, as he took it with the artificial fly at a time when they did 
not readity bite at any bait. The Indians brought to our camp about the same time what I 
supposed to be the same species, some of them two feet long. 
When fresh its colors were as follows; Back, dark olive; sides, silvery, with green and 
purple reflections; belly, white; iris, yellow; spots black.—C. 
According to Dr. Girard, the arrangement of the rays is as follows: Br. 11; p. 14; Y, ?; A, 13; 
D, 15. For reasons that seem to me sufficiently good, I have considered this fish distinct from 
that described as F. clarkii by Richardson, and have named it in honor of my good friend 
Governor Charles H. Mason, of Washington Territory, who has so frequently aided me in 
adding to my collections specimens of great interest and value in various branches of natural 
history. 
Specimens of this trout were obtained by the writer at Fort Dalles, on the Columbia, from 
the same waters as the other brook trout was taken. It runs up the small streams a little later 
than the latter, and is distinguishable at a glance by its smaller and less numerous black spots, 
and by wanting the red patches under the jaws, already alluded to. In habits, size, Ac., it is 
almost precisely similar to the other species, and is taken with the same baits, jumping readily 
at the artificial fly, and freely taking meat, grasshoppers, worms, and similar food. 
There is a trout very common in the small streams emptying into Puget Sound, near Fort 
Steilacoom, during the latter summer months and early autumn, which resembles this species 
c Alludiug to a fish known to the tribes of New Caledonia as the “ suppai.”
