back; the firft about three inches from the fnout, and 
lupported by thirteen rays; the fecond, which is placed 
near the tail, is thick, fat, and altogether without

as the generic mark of all the fifties of the trout kind *. 
Tliis filli, like the charr, is of an alpine nature, and 
inhabits the lakes of the mountainous parts of Europe ; 
inch as, Switzerland, Savoy, Norway, Sweden, Lapland, 
and Scotland : Into the laft mentioned country, it is faid to 
have been introduced from France by the unfortunate ®>ueen 
Mary ; a circumftance rendered probable by the French 
name vangis, given it by the inhabitants in the vicinity 
of Lochmaben. The Britijh name of gwiniad is bellowed 
upon it from the whitenefs of its feales f. The gwiniad 
is a gregarious filh ; and approaches the fhores in vail 
lhoals in fummer and fpring, which are the feafons in 
which it is taken : In fome of the German lakes it is 
caught in vail abundance, and falted up for fale in the 
neighbouring towns. The flelh is infipid, and will not 
preferve for any time without fait. 
There are twenty-nine different fpecies of fifties belong-

rieties, are all that is known in Britain,
