Long-finned Charr 



back somewhat elevated, less compressed than in Salvelinus 

 fontinaJis; head large, snout broad, flattened above; mouth large, 

 the maxillary reaching past the eye; fins short, the caudal slightly 

 forked or almost truncate. General colour, olivaceous, the sides 

 with round red or orange spots nearly as large as the eye, the 

 back with similar but smaller spots, and without reticulations, a 

 feature of colouration which at once distinguishes this from all 

 other American trout; lower fins coloured much as in S. fontinali^, 

 dusky, with a pale stripe in front, followed by a darker one. 

 Sea-run examples are silvery, with the spots pale or obsolete. 



Long-finned Charr 



Salvelinus alipcs (Richardson) 



In northern Europe, from the Swiss lakes and the lochs of 

 Scotland northward, in all cold waters, is found the Saibling or 

 European charr, Salvelinus alpiniis. This charr is represented in 

 America by several forms, most of which have usually ranked as 

 subspecies. The first of these is the long-finned charr which in- 

 habits the lakes of Greenland and Boothia Felix about Prince 

 Regent Inlet. 



In this charr the body is elongate, the head moderate, the 

 snout long and pointed, with the lower jaw projecting beyond 

 the upper; teeth small; maxillary long and narrow, reaching 

 beyond the eye; preopercle very short, with a very short lower 

 limb; opercle and preopercle very conspicuously and deeply 

 striated; fins much developed, the dorsal much higher than long; 

 pectoral very long, reaching more than halfway to ventrals, which 

 are very long; caudal well forked. 



Greenland Charr 



Salvelinus stagnalis (Fabricius) 



This is another charr occuring in the waters of Greenland, 

 Boothia Felix and neighbouring regions. Body rather elongate; 

 pectoral short, i| in head, not reaching half-way to ventrals; dor- 

 sal about as high as long, the longest ray \\ in head; gillrakers 

 9-|-i^; slender and nearly straight, the longest 2^ in eye. 



Colour, dark green, with- lighter irregular green streaks, 

 silvery below; sides everywhere with pale pink spots, the largest
