10 Descriptions of Several New Species of SalmonidcB^ etc. 



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 lbs. 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. 



Habitat. — N. W. coast of America. Enters tlie streams along 

 Paget Sound in great numbers in autumn. 



All the specimens preserved of this species were unfortu- 

 nately lost in transitu. They arrive in the small rivers and 

 creeks, emptying into Puget Sound, about the first week in Octo- 

 ber, coming in great numbers, and remaining in the streams 

 until about the 1st of April. They are the most inferior of all 

 the kinds of salmon known in that region. 



Ifote. — The foregoing notices of the new species of salmon 

 from the western coast of America are necessarily incomplete, 

 as but few specimens of either kind have as yet been received. 

 More extended and useful descriptions of each will be fur- 

 nished, as soon as the reception of additional material will admit. 

 Many anatomical characteristics, such as the number of fin-rays, 

 teeth, &c., have been omitted, owing to the imperfect condition 

 of many of the specimens from which the descriptions were 

 made up.
