Oculis sinistris. It is owing to a want of attention 
to this circumstance that so many errors have 
crept into works of natural history, relative to the 
Fishes of this genus ; for if the engraver is not 
careful to reverse the drawing, it will give the spe- 
cies in a wrong division of the genus. I cannot 
acquit the artists employed in my own works of 
some inattention in this respect. Of the species 
with the eyes to the right the common Flounder 
furnishes a good example, and of those with eyes 
to the left the Turbot. 
The numerous genus CJustodon is remarkable 
for the peculiar elegance and variety of its co- 
lours in the diflerent species, which are often dis- 
posed in the form pf bands or zones, either trans- 
verse or longitudinal. Most of these Fishes are 
natives of the Indian and American seas. Their 
teeth are small, very numerous, close-set, and 
resemble so many bristles. 
Another genus, greatly allied to Chjetodon, 
and one intermixed with it, differs in having 
strong and broad teeth, and a very strong upright 
spine on each side the base of the tail. It is a 
lately instituted genus, and is called AcanthuruSi 
or Thorn-Tail,
