Salnio tsuppitch, liichards. Fuun. Bor.-Ainer. iii. p. 224; Sucklvy in 

 Nat. Hist. Wash. Ten: p. 327. 



Richardson gives the following characters : — 



B. i;3. D. 12. A. 13. pVert. 64.] 



Back of body and head studded with oval and circular spots ; 

 sides and fins, including the caudal, destitute of spots ; back mesially 

 bluish grey, passing on the back of the head into blackish grey, and 

 on the sides into yellowish grey with a greenish tinge and silvery 

 white. General colour of the fins ashy grey. Jaws fuUy armed with 

 minute sharp teeth ; a single row on each palate-bone ; a very few on 

 the anterior end of the vomer, in a single series ; and a double row on 

 the tongue. Head small, exactly conical, tcnninating in a pointed 

 snout. Commissure of mouth very slightly oblique. Convexity of 

 dorsal profile rising gradually to origin of first dorsal, and declining 

 thence to the tail. Caudal forked. 



A migratory Trout from the Columbia River. 



37. Salmo gairdnerii. 



Salmo gairdnerii, Richards. Faun. Bor.-Amer. iii. p. 221. 

 The material on which this species has been founded was quite 

 insufficient for that pm-pose, and the species for which this name has 

 been intended is not likely to be ever recognized. 



B. 11-12. P. 13. V. 11. A. 12. Vert. 64. 



The only traces of variegated marking are a few faint spots at the 

 root of the caudal. Tail terminating in a slightly semilunar outline. 

 Vomer armed with a double row for two-thirds of its anterior portion. 

 When the soft parts of the mandible are entirely removed, the pro^ 

 jecting lower edge of the articular piece of the lower jaw is acutely 

 serrated. 



This fish ascends the river Columbia in the month of June in 

 much smaller numbers than the Quinnat ; its average weight is 

 between six and seven pounds. 



Girard adopted the name ''gairdnerii''^ for a specimen from the 

 Klamath river, Oregon Territory, which he describes and figures in 

 Proc. Ac. Nat. Sc. PhUad. 1856, p. 219, and U. S. Pac. R. R. Exp. 

 Fish. p. 313, pi. 71. figs. 1-4. There is nothing whatever to indicate 

 that this identification is correct ; on the contrary, it would appear 

 that Dr. Gairdner's fish had a double series of vomerine teeth, whilst 

 Girard referred his fish to Fario (Valenc). However, we may men- 

 tion that this gentleman is most inaccurate in his description of the 

 teeth of Salmonoids. A few years later (Proc. Ac. Nat. Sc. PhUad. 

 1858, p. 224) he recognized the discrepancies between his and Rich- 

 ardson's descriptions, naming his specimens Fario newherrii. If the 

 figure given by him is correct, and the scales are as small as repre- 

 sented, we may presume that the typical specimen of this F. gairdnerii 

 (Girard) is a J'oung female oi Salmo steUatus.
