as the Indians believe, to something peculiar in the water. — (Kennerly, in 

 MSS.) Dr. Kennerly in a note made on the 13th of September, 1859, says 

 that he had that day " observed many jdead salmon floating on the 

 lake." 



Mr. Gibbs found the species in fuU run August 1, 1857, in the salt 

 water on the west side of Lnmmi Island.

Sp. Ch. — A slender fish for the genus. Head, measured from snout 

 to distal edge of oi^erculum, contained about four and three-quarter 

 times in the total length ; measured from snout to nape, it is contained 

 seven and a half times. When the pectorals ara smoothed backward 

 against the belly the point of greatest girth is along a line drawn verti- 

 cally neai- their en<ls; fi-om whence to the snout there is a regular curve, 

 but posteriorly the line of the back is quite straight, the body being 

 somewhat compressed latterly and tapering. Scales much smaller than 

 in individuals of ^S*. iridea, Gibbons, of the same size. They are very deli- 

 cate and easily detached. Caudal, forked. Back aud sides, low down, are 

 covered with spots (about two lines in diameter in a fish one foot long;) 

 those near the lateral line being of a beautiful rose-color ; those above 

 and below, cream-colored or white. Tail forked. A small clump of 

 teeth on anterior extremity of the vomer as in the chars, or Salvelini of 

 Nilsson. 



Diagnosis. — Known from all the Pacific fronts by the red spots on 

 the sides, and whitish ones on the back. 



In 1850 Dr. Girard described a trout sent by me from the Dalles on the 

 Columbia Eiver. The specimen was very much broken, and the descrip- 

 tion vague. I have, however, succeeded in identifyiug other specimens 

 sent by Dr. Kennerly from Puget Sound, by comparing these with the 

 remains of the original typical specimen. 



In two of these fish in the Smithsonian collection there are two teeth 

 on the head of the vomer, and on each side, and two on the shaft. One 

 specimen had 42. scales above the lateral line to middle of the back ; 

 40 below the lateral line, and 156 upon it.

Dr. Girard first described this trout, giving it the name of S. specta- 

 bilis, but which I have been obliged to change, as there had already been 

 described by Valenciennes, in his Hist. Nat. des Poissons, a species un-
