— Clafs IV. WE Ni a, 269 
It has long ago been obferved in Cambden*, that 
thefe fifh never wander into the Dee, nor the falmon 
never ventures into the lake: this muft be allowed to 
be generally the cafe ; but by accident the firft have 
been known toftray as faras Llandrillo, fix miles down 
the river, and a falmon has now and then been found 
trefpaffing in the lake **, 
The largeft Gwiniad we ever heard of weighed 
between three and four pounds: we have a Ferre 
we brought with us out of Suiizerland, that is fifteen 
inches long; but thefe are uncommon fizes : the 
- fifh.which we defcribe was eleven inches long, its 
ereateft depth three. 
The head {mall, fmooth, and of a dufky hue:_ 
the eyes very large: the pupil of a deep blue: the 
nofe blunt at the end: the jaws of equal length: 
the mouth {mall and toothlefs: the branchioftegous 
rays nine: the covers of the gills filvery, powdered 
with black. 
The back is a little arched, and flightly carinated : 
the color, as far as the lateral line, gloffed with deep 
blue and purple, but towards the lines affumes a 
filvery caft, tinged with gold, beneath which thofe 
colors entirely prevale. 
The fide line is quite ftrait, and confifts of a feries 
of diftinct {pots of adufky hue: the belly is a little 
prominent, and quite flat on the bottom. 
The firft dorfal fin is placed almoft in the middle, 
and confifts of fourteen branched rays; the fecond 
isthin, tranfparent, and not diftant from the tail.
