SALMONID^. 133 



the mouth is shut, ending acutely, but when viewed from above, or in 

 front, the snout is obtuse. The greatest depth of the body is scarcely 

 one-fifth of the total length, caudal included. The head is small, 

 being one-sixth of the total length, excluding the caudal, or one- 

 seventh including it. Orbit large, distant half its diameter from the 

 snout, and two diameters from the edge of the gill-cover. Nostrils 

 midway between the orbit and the tip of the snout. Mouth not cloven 

 as far back as the edge of the orbit. Intermaxillaries longer than in 

 the Coregoni, but overlapping the articular end of the .labials less 

 than in the TrvMa. Labials, thin elliptical plates, the posterior 

 piece lanceolate, and as broad as the anterior one. . Under jaw tolera- 

 bly strong and rounded at the tip. 



" The teeth are small, subulate, pointed, and slightly curved, stand- 

 ing in a single series on the iritermaxillaries, in two rows on the pala- 

 tines, and in clusters of six or seven on the vomer. The tongue is 

 smooth, but the pharyngeal bones, and cartilaginous rakers of the 

 branchial arches are rough. 



" Of the gill-covers, the preoperculum has the form of a wide mo- 

 derately curved crescent. The suboperculum is more than half the 

 height of the operculum, not exceeding it in length. Interoperculum, 

 small, and acute-angled. 



"The doi^al fin has twenty-three rays, the pectorals fifteen, the 

 ventrals nine, the anal thirteen, and the caudal nineteen. 



" Although this exquisitely beautiful and very game fish, is not, as I 

 have previously observed, properly speaking, a pative either of the 

 United States or the British provinces, being found only in the 

 northern part of the unsettled regions of British America, and the 

 waters flowing from Great Slave lake into the Arctic ocean, still, so 

 wonderftyjiy are the facilities of travel increasing through the West and 

 North, and so great is the enthusiasm of the Anglo-Norman race in all 

 matters connected with sporting and sportsmanship, that it by no means 

 appears to me impossible that, before many years have elapsed, the 

 lovers of the angle, whether of English or American birth, will be 

 found casting the fly in the glass-clear rapids of the Winter river, 

 and the other waters of those untamed regions, for the Arctic Gray- 

 ling, and the many beautiful species of Salmon that are to be taken
