the ventrals; rays 12, the two anterior simple. Adipose nearly opposite to the posterior rays 
of the anal. Pectorals with 15 rays; ventrals with 10. Anal stout, with 14 or 15 rays. 
Caudal marked with dark oval spots, more distinct in the smaller fish. 
From the preceding account I have but little doubt that the species found with us is the 
same as that of Pallas, and have accordingly adopted his synonym. It is not unlikely that 
more of our species may prove identical with those of Kamtschatka. This theory is not 
opposed by the physical conformation of the two continents, which, approaching each other 
so closely at the north, are also nearly joined at a comparatively southern point by the chain 
of islands formerly the Aleutian archipelago. 
The present species may be distinguished from the S. Scouleri by its smaller size, the 
prominent hump in the males, its smaller scales, and the fine regular teeth along the sides of 
the jaws. The teeth of the S. Scouleri are scattered irregularly, and are generally large; but 
by no means unifoi'm in size along the sides of the maxillaries.—T. 
SALMO CANIS, Suckley. 
Dog Salmon ; Spotted Salmon. 
Syn. — Salmo canis , Suckley, Ann. N. Y. Lyc. Dee. 1858.— Lekai, Chinook jargon ; Tlh-whai, Nisquallies. 
Sp. Ch. — Male : Gape line of mouth much arched ; intermaxillary protuberance well marked, decurved ; fleshy prolonga¬ 
tion beyond chin rather thick ; jaws fully provided with large strong teeth, so large as to give rise to the name of dog salmon ; 
dorsal outline moderately arched ; body compressed laterally, but rather deep ; weight of full grown adult rarely exceeds 12 
or 14 pounds. Colors, upon first arrival into fresh water, of a dingy greenish olive on the back, fading into brassy yellow on 
the sides, and to dingy yellowish white on the belly; sides more or less maculated with large alternate patches of dingy green 
and purplish red ; flesh pale, and of inferior quality ; upper fins and tail dark. 
Hab .—Northwest coast of America. Enters the streams along Puget Sound in great numbers in autumn. 
The spotted or lekai salmon enters the rivers of Puget Sound in great numbers every 
autumn, generally appearing between September 15 and October 10. They come in vast 
numbers, and arrive so simultaneously as to seem to be in shoals, though probably that is 
occasioned not by a gregarious character, but by the same instinct causing all the individuals 
to leave the sea at about the same period for the purpose of procreation. 
They are not a finely flavored fish, even when “fresh run,” many individuals being at that 
time in bad condition—a condition unusual among salmon just quitting salt water. After a 
short residence in fresh water all become poor and unsavory, and some even intolerably rank. 
Upon first arrival the sickly fish are readily distinguished by the natives by their colors, the 
best fish being of a leaden olive or dingy green on the back, and a yellowish white along the 
belly; the poor ones are of various shades and tints of dingy green and yellow, more or less 
maculated on the sides with purplish and black blotches. They enter, by preference, the 
smaller streams. 
Owing to the large jaws and long ferocious-looking teeth of the species they have obtained 
from the whites the name of dog-salmon. Yast numbers are taken by the Indians with spears, 
gaff hooks, weirs, &c., and dried for winter use. Upon their arrival in September and October 
their roes are nearly mature. 
It is interesting to witness their persevering efforts to run up shallows, and in overcoming 
insurmountable obstacles, even running out of water upon the shores , in their blind eagerness to 
surmount impossibilities and reach the headwaters of the stream to deposit their spawn. In 
endeavoring to ascend high falls, and in passing through rocky, violent passages, their snouts
