yellow predominate ; the belly is reddish white ; the dorsal fin has the same hue 

 with the back, the others are reddish. 



The scales have for the most part an irregular oval shape, and are very large, being 

 three quarters of an inch long ; they are nearly of equal size over the whole body. 

 The uncovered portion of each scale is strongly radiated, and broader than long ; 



their lustre is considerable. 



The head is proportionably smaller than that of the Namay-peeth, and the snout 

 is more acute ; the gill-openings are small ; the lustre of the opercula is similiar to 

 that of the scales ; the orbit is orbicular, rather large and placed in the middle of 

 the head. 



The mouth has a much smaller orifice than that of the namay-peeth and is placed 

 farther back, but not so far back as that of the immediately preceding species, the 

 meethquamay-peeth, When the jaws are retracted, the snout projects about half 

 an inch beyond them, but when protruded the edge of the upper jaw and snout are 

 even. The lips instead of being furnished with papillae, as in the preceding species, 

 are sulcated perpendicularly in a very regular manner. 



The palate, pharynx, and contents of the abdompn of this fish nearly correspond 

 with those of the namay-peeth, they are, however, in general proportionably smaller. 

 The oesophagus is remarkably contracted, which gives to the commencement of 

 the gut an appearance of dilatation. The intestines are not connected to the 

 parietes of the abdomen by such numerous folds as in the namay-peeth. The 

 length of the alimentary canal is to that of the fish, as 2.56 to 1. The lining of 



the abdomen is white. 



The air-bladder in this species is divided into three portions, the central of which 



is the largest, and communicates with the oesophagus.

structure of the lips. The three species we have described may be also readily dis- 

 criminated by the colour of the peritonaeum, and number of portions into which the 

 air-bladder is divided. The usual length of this fish is sixteen inches, 

 the caudal fin. 



The wawpawhawkeeshew is considered by the Indians to be hybrid betwixt the 

 namay-peeth and the attihhawmegh (Coregonus albus.)
