variety is the silver salnion, Avith forlced tail. It is not very abundant, and does not run in 
'schools.' Weight, 15 to 18 pounds; average, 13." He also mentions a small wispptted salmon, 
which the Indians say grows no longer than 18 inches. 
The Indians probably confuse several species under the name of sais^/p, and perhaps consider 
all silvery salmon, with red flesh and forked tails, as one species. 
Note. — Mr. Girard describes the species as follows. The color being taken from the 
preserved specimens are, of course, unnatural, and should have those given above substituted: 
" Sp. Ch. — Body very much depressed, rather deep upon its middle region, and quite tapering 
posteriorly. Head moderate, constituting the fifth of the entire length. Jaws equal. JNIaxillary 
slightly curved; its free extremity extending to a vertical line drawn posteriorly to the orbit. 
Anterior margin of dorsal fin nearer the extremity of the snout than the insertion of the caudal 
fin. Bluish gray above; silvery along the middle of the flanks; yellowish beneath." — Girard.

Figures — The plate (LXIX, figs. 1 — 4) in the Pacific Railroad Reports, vol. X, represents the Salmo Gihbsii and not this 
species.— (See remarlcs oii S. GMsii.) 
Si'. Cii. — Clonvexity of dorsal profile rising" gradually to origin of first dorsal, declining from tlience to the tail Caudal 
forked. Head smaW, exacdy conical, terminating in ti. pointed snout. Ccmtnissure of mouth very sliglitly oblique. Back of body 
and head studded with oval and circular spots ; sides and Jins, including the caudal, destitute of spUs. Teeth minute and sharp ; 
a single row on each palate bone, a very few on the anterior end of the vomer, and a doulilc row on the tongue. [The 
foregoing description is deduced from Dr. Gairdner's notes in Rich. F. B. A. p. 224.] 
The portions italicized in the above summary of specific characters, are those differing strongly 
from a correct description of the fish taken by Dr. Girard for this species, and described by me 
as the S. Gihbsii. 
Dr. Gairdner says that this salmon ascends the Columbia with the ekewan, (hite in August 
and during September.) The formula he gives for the 7'ays is as follows: "Br. 13; P. 13; V. 
10; A. 13; D. 12—0." 
Sir John Richardson says that "a spine containing sixty-four vertebrcT?, and an under jaw 
Avith ten curved teeth in each limb," Avere all the bones that he could Avith any degree of 
correctness identify. (This Avas oAving to the damaged condition of the specimens received.) 
The dimensions in detail of a specimen tAventy-one inches in length are given by Dr. Gairdner. 
In this the anterior margin of the dorsal Avas one inch nearer the end of the tail than to the 
tip of the snout. The teeth Avere "equal in size Avith those of the S. Gairdneri, or perhaps 
rather larger." 
I have myself ne\^er succeeded in obtaining this salmon, but am strongly inclined to the 
opinion that it is identical Avitli the fish noAv known to the settlers on the Columbia as the 
while sedmon." — (See remarks on the S. paucidens.)
