The Turbot is to be easily discriminated from the analogous kinds 
of flounders, by the many sub-acute tubercles, with which both the 
upper, and the under surface of this fish are beset. There is besides a 
remarkable rotundity in the outline of this species, by which it may 
be known. The colour on tlie upper surface is yellow, varied, clouded 
and spotted with darker brown. The skin is covered with scales, 
but those are extremely small. It should be also oberved, that the 
tubercles on the upper surface are larger and more numerous than 
those on the under-side, the colour of which is perfectly white. 
The peculiar excellence of the Turbot is so very generally acknow- 
ledged, that it might be thought superfluous on our part to speak in 
commendation of it. 
Tliere is a species of this tribe of flat fishes, called by English 
writers the Pearl, the Pleuronectes Rhombus of Linnaeus, which very 
much resembles the Turbot, but the surface of it is uniformly des- 
titute of the prominent tubercles, which are so very obvious on that 
fish. The flesh of this is inferior in point of firmness, delicacy and 
flavour to that of Turbot, for which it is sometimes sold. 
Upon the information of Bloch, and various other Ichthyologists, 
who have entered minutely into the history of this fish, we may con- 
ceive the Turbot to be a very general inhabitant of all the Northern 
Seas, and also of the Mediteiranean. Many of our own coasts
