CRUISE OF THE STEAMER CORWIN. 95 



FISHEB. 



CATOSTOMID.E. 



Catostomus longirostris Le Scuer. Northern Sucker. 



On July 24: I obtaiued several fishes of this si)L'cies by dragging a small seine, with Marsh's 

 lielp, through an old high-water channel, in which the fishes had been cut oti: by the falling of 

 the river. These were all fine large fishes, of excellent flavor. Although j)lentiful in this old 

 channel, they were seldom seen elsewhere. The reason of this may have been that the root- 

 fiber nets used by the natives in catching salmon were not well adapted to the capture of bottom 

 fishes, such as suckers. 



Two specimens; Upper Kowak, July 24. 



SALMONID^. 



Coregonus quadrilateralis Richardson. Whitefish. 

 Frequently taken in the salmon seines. 

 One specimen; Middle Kowak, August. 



Coregonus kennicotti Miliirr. 



Not very common. Those seen were of large size, being sometimes as long as adidt salmon.

Oncorhynohus gorbuscha WalbaKm. Humpback Salmon. 



Probably not more than half a dozen individuals of this species were seen during our voy- 

 aging on the river, although large numbers of fishes were examined at every village of the 

 natives. 



One specimen; Middle Kowak, August 1. 



Oncorhynohus keta Walbaniii. Doo Salmon. 



The prevailing salmon in the Kowak. Great numbers dried by tlie people. 



Salvelinus namaycush Wnlhaam. Great Lake Trout. 



Mr. Cantwt'll ))rouglit me a large specimen of tliis magnificent trout from tlae lake in which 

 the Kowak heads, where lie found it in abundance. The lake is called Car-loog-ah-look-tah by 

 the natives, in reference to the great size of the trout inhabiting it. The species was not met 

 with elsewhere.

Common in the Kowak. Found also at Ounalaska.
