kennicotti, in honor of Robert Kennicott. Captain E. P. 

 Herendeen, of the Signal Service Expedition to Point 

 Barrow, fonnd this white-fish in Meade River in October, 

 1882. This stream is a tribntary of tlie Arctic Ocean to tlie 

 eastward of Point Barrow. The southern limit of this 

 species is not known, but it probably extends at le^st as 

 far south as the Bristol Bay region. The great size and fine 

 quality of its flesh make it one of the most important 

 food-flshes of the territory. 



The round white-fish, shad-waiter, or chivey of New 

 England {Coregonus quadrilaieralis, Plate I, fig. 2), ex- 

 tends through the upper great lake region, the Northwest 

 Territory, and other i^arts of British Columbia, into 

 Alaska. Specimens have been obtained as far north as 

 the Kuwuk, or Putnam River, a tributary of Hotham Inlet. 

 This flsh does not reach a large size, seldom exceeding two 

 pounds in weight, but it is very abundant and very palat- 

 able, .and, consequently, is an important food resource. 



A third species, called Coregonus Jaurettce, Plate I, 

 fig. 3, abounds from the Bristol Bay region to Point Bar- 

 row. It is a little larger than the round white-fish, but 

 seldom exceeds three pounds in weight. It resembles the 

 so-called lake herring (C. artedi) of the great lakes, and 

 is an excellent food species. 



The fourth species is known as the hump-back white- 

 fish, and was named in honor of Mr. E. W. Nelson [Core- 

 gonus nelsoni, Plate II, flg. 4). It bears considerable 

 resemblance to one of the Siberian species, from which, 

 however, it can be readily distinguished. As food for man 

 it has little value, but enormous quantities are consumed 

 by the dogs. This species is found in all parts of the 

 territory from the peninsula of Alaska northward. Breed- 

 ing males have a very large hump developed on the nape, 

 which is compressed to a thin edge. 



The fifth specie^ of white-fishA(Plate II, fig. 5) is the
