similarly spotted. Region beneath the lateral line, nnicolor ; silvery along the 

 middle of the flanks, and yellowish on the belly. Inferior fins unicolor. Head, 

 aboTe blackish grey, its sides bluish grey. 



A specimen from Columbia river, was preserved by Dr. Geo. Suckley, under 

 Gov. I. I. Stevens. 



3. Salmo spectabilis, Grd. Body subfusiform in profile, very much com- 

 pressed, the head forming about the fourth of the total length. Maxillary bone 

 curved, extending to a vertical line passing somewhat posteriorly to the entire 

 orbit. Anterior margin of dorsal fin, a little nearer the extremity of the snout 

 than the base of the caudal. Bluish grey above ; silvery beneath. Dorsal region 

 and upper portion of the flanks spread over with light spots. 



By its general appearance, this species resembles Sal/no hoodii most, but may 

 readily be distinguished from it by a more elongated and elliptical head, hence 

 a mouth more deeply cleft, with the maxillary extending further back. 



Specimens collected at St. Mary's Mission, Flathead valley, Oregon, by Dr. 

 Geo. Suckley, U. S. A., under Gov. I. I. Stevens.

Gen. char. All the characters of the salmons, differing from the latter by 

 the presence of only one row of teeth upon the shaft of the vomer.

1. Fario aurora, Grd. Red Char of Lewis and Clarke. Body fusiform, com- 

 pressed ; head forming the fourth of the length, the caudal fin excluded. Upper 

 jaw longest. Maxillary gently undulating ; its posterior extremity extending to 

 a vertical line passing considerably behind the entire orbit. Anterior margin 

 of dorsal fin equidistant between tlae tip of the snout and the insertion of the 

 caudal. Ground color greyish silvery above ; sides and belly yellowish orange 

 Dorsal fin spotted. 



Specimens collected at Astoria, 0. T., by Lt. W. P. Trowbridge, U. S. A. 



2. Fario tscppitch, Grd. Salmo tsuppitch, Rich. Faun. Bor. Amer. iii. 1836, 

 324. Storer, Synops. 1846, 197. Salmon Trout oi i\iQ settlers. 



Body very much elongated, compressed, fusiform in profile ; head forming 

 about the sixth of the total length. Snout rounded, with the jaws subequal. 

 Maxillary gently curved, dilated posteriorly, and extending to a vertical line 

 passing slightly behind the orbit. Anterior margin of dorsal fin nearer the ex- 

 tremity of the snout than the insertion of the caudal fin. Ground color of dorsal 

 region olivaceous, clouded with bluish brown, and scattered about with round- 

 ish black spots which extend over the dorsal, the adipose and the caudal 

 fins. Upper surface of head bluish black. Sides and inferior region of the 

 body unicolor, yellowish brown ; inferior fins unicolor also. Sides of head 

 yellowish. 



A female specimen 26 inches long, caught at Fort Dallas on the Columbia 

 River, Oregon, was skinned and preserved by Dr. Geo. Suckley, U. S. A., under 

 Gov. I. I. Stevens. 



3. Fario argyreus, Grd. Body very much compressed, rather deep upon its 

 middle region and quite tapering posteriorly. Head moderate, constituting the 

 fifth of the entire length. Jaws equal. Maxillary slightly curved ; its free ex- 

 tremity 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 grey above ; silvery along the middle of the flanks ; yellowish 

 white beneath. 



This species is quite characteristic in its outline, since it is much more taper- 

 ing towards the tail than in any other of its congeners. In other respects it re- 

 sembles somewhat Fario aurora, but its elongated and low anal fin will distin- 

 guish it from the latter at the very first glance.
