ROUND-FISH. 97 
CHAPTER IV. 
THE ROUND-FISH, HERRINGS, AND VIVIPAROUS FISH. 
Tue Rounp-Fisu (Coregonus guadrilateralis).— 
Sp. Ch.: Colour, yellowish-brown, paler on the 
sides and belly than on the back; scales bright 
and glittering, each edged with a narrow border 
of dark-grey ; cheeks, fins, and tail, a deeper tint of 
the same colour as that on the back; head one- 
sixth of the length (without the caudal); mouth 
very small, under-jaw shorter than the upper— 
no teeth perceptible. 
This fish has a very wide geographical range, 
being found as far north (according to Sir J. 
Richardson) as the Mackenzie and Copper- 
mine rivers, east of the Rocky Mountains, and 
latitude 49° N. the western side; how much 
farther they range north of 49° I had no oppor- 
tunity of judging. 
This handsome and delicious fish, one of the 
Salmonide, is most valuable as an article of food 
to the Indians, west of the Rocky Mountains,
