The Reuronectes Flesus, or true Flounder, approaches in 
the general appearance so nearly to the Plaise, Pleuronectes Pla- 
tessa, and is so frequently confounded with it, that it will not 
be amiss to advert to both, in order to point out the precise cha- 
racter by which they are to be distinguished. The Plaise is usually 
of a much larger size than the Flounder; the body rather wider, and 
its thickness proportionately less. The head of the Plaise is beset 
behind the left eye with a row of distinct tubercles, that reach to the 
lateral Ime, none of ^vhich appear on the head of the true Flounder. 
Tne upper surface of the body and fins, are marked with large roundish 
•pots of a bright orange colour, which are paler or deeper in different 
fishes, but are almost invariably present, and those are never, or very 
rarely seen on the Flounder, although this fish is subject to more consi- 
derable variations, than almost any other. I’he flesh of the true Floun- 
der is firmer, and of a flavour far superior to the Plaise ; it Is also 
much less frequent, the Plaise being the fish commonly sold for 
Flounders in the London markets.
