worms. It has been known, though rarely, to take a hook baited with a small piece 

 of meat. The structure of its stomach displays in an eminent degree that peculiar 

 thickness of coats which has been observed in many fish of this genus. 



We caught some fine attihhawmegh at the mouth of the Copper-Mine River, and 

 in Bathurst's Inlet, and it abounds in every river and lake in the country. It forms 

 a most delicious food, and at many posts it is the sole article of diet for years 

 together, without producing satiety. It spawns in the month of October.

This fish bears so strong a resemblance to a lean individual of the preceding 

 species, that it requires the eye of an experienced fisherman to detect the difference 

 on a cursory view. It is, however, smaller in all its parts, and differs remarkably in 

 the comparative thinness of the coats of its stomach, which are scarcely thicker than 

 those of an ordinary trout. 



The Cree name of this fish ottonneebees, has been corrupted by the traders into 

 -tullibee. It is inferior to the attihhawmegh as an article of food ; but in its habits 

 and food it appears to correspond with that fish, notwithstanding the difference in 

 the structure of their stomachs. It is found in most of the lakes, and we caught 

 a few in the sea at the mouth of the Copper-Mine River, but it is much more rare 

 than the attihhawmegh.

The body has a compressed, elliptical form, tapering gradually towards the tail; 

 the head is small, and the snout, seen sideways, appears acute, but otherwise obtuse. 



The lateral line is very nearly straight, and nearer to the back than to the belly. 



Colour. — Its sides are tinged with lavender-purple, mixed with bluish grey, with- 

 out streaks; the belly is blackish grey, with several irregular white blotches, and 

 there are five or six longitudinal rows of uniform quadrangular spots of Prussian blue 

 on the anterior part of the body. There is a large blue mark underneath the lower 

 jaw on each side. The dorsal fin, which forms a prominent feature in the fish, is 

 of a blackish-grey colour, with some lighter blotches. Superiorly it has a narrow 

 margin of light lake-red, and posteriorly it is beautifully ornamented with spots of 

 Berlin blue. The ventrals are streaked with red, and whitish lines in the direction 

 of their rays. _ The scales are moderately large, and have no great lustre ; their exte-
