nature of the lake bottom, and whether or not the individual 

 may have been caught during the breeding season. When in 

 full vigour, in October, during the spawning month, the males, 

 with the exception of the unusually large individuals, will be 

 found very much alike, and more or less of a dark greenish- 

 grey, getting fainter towards the belly, which is dappled with 

 dull and purer white patches. The yellowish-grey spots, some 

 as large as buck-shot, extend over the body and tail. The 

 latter is said not to be the case in the namaycush, but from 

 Agassiz' drawing,* they are evidently present on the tail of the 

 siscowet. 



There is more or less of an orange tinge on the lower fins, 

 especially the pectorals, but the purple in the inner surface 

 of the mouth of the namaycush is seemingly absent in the 

 togue. 



In full health and vigour the Togue presents a close resem- 

 blance to the full-grown salmon. The head forms one-fourth of 

 the total length from the snout to the tip of the caudal. It is 

 rather flat above and convex in profile. (See pages 235 and 

 237.) The eye is midway between the tip of the snout and the 

 nape, and about twice as near to the former as to the hinder 

 edge of the gill cover. The labials (p. 237, #) are fully three times 

 as long as the intermaxillaries (c), thus contrasting with the 

 namaycush, but identical with the siscowet. The labial crest, 

 (b) does not extend beyond the extremity of the bone, as it does 

 in the namaycush. The length of the lower jaw is equal to that 

 of the upper surface of the head. Like other lake and river 

 salmonoids, it has a prominent knob on the extremity of the 

 lower jaw, which in ordinary sized males is not permanent, 

 and only seen during the spawning season. In old males, 

 however, it is very conspicuous, and, as in the salmon, fits 

 into a cavity in the upper jaw ; indeed it would appear to 

 become developed with age, so that all very large salmonoids 

 have it more or less throughout the year. The gill covers
