T h e body oval, much compressed ; scales small, orbicular, imbricate, tenacious.
T h e bead small, compressed, sh a rp; the rostrum without scales. T h e mouth large, ascending o bliqu e ly; the
jaws long, straiglit, e xtractile; the teeth o f unequal size, not in a close row, long, sharp, a little curve. T h e
tongue short, roundish, emarginate, smooth at the point, rough towards the root. T h e palate set with small
teeth. T h e eyes on the right side, large, globular, prominent, both on a line, one close to the vertex, the
other near the posterior edge o f the mouth. T h e nostrils small, round, one before the other, on a line with
the superior edge o f the orbit. T h e branchial opercula consist o f two lamín®, the posterior pointed; the
branchial membrane o f seven rays.
T h e trunk. T h e back and be lly carinate, the sides compressed, very little convex; the upper or right side
(which is common to this genus) dusky, the opposite side white. T h e tail flat. T h e lateral line rising from
the top o f the posterior operculum, after inclining by a gentle bend, runs straight along the middle o f the tail.
T h e anus is situated near the ventral fins in the carina o f the belly.
The^H L T h e dorsal rising an inch and a ha lf from the rostrum, is continued to witliin the same distance
o f the caudal fin ; the anal nearly o f the same length, terminates exactly opposite: the rays o f both incline
to the tail. T h e pectoral fins situated low, and consist o f short declining ra y s ; the ventral a little more forward
than the pectoral. T h e caudal undivided, oblong, juts out a little obtusely at the middle.
T h e colour o f the upper side a dark g ray, the lower, or blind side, a dull white.

T he W y oblong-ovate, much compressed; covered with very small orbicular scales, ciliate, imbricate, and
rough to the toucii ; dark on one side and whitish on the other.
T h e head very small, short, compressed, the front and rostrum carinated.
T h e mouth terminal, small, curve; the lips thickish, the lower (on the right side) being curled and hairy.
A few very small, sharp, teeth only visible on the left side, at the corner o f the curled mouth. T h e tongue
small, smooth, immoveable. T h e eyes near tlie rostrum, and close on the corner o f tlie mouth, small, orbicular.
T h e nostrils double, the anterior vvith a small valve.
T h e branchial operculum consists o f one lamina ; the membrane concealed.
T h e tmnk. T h e back and abdomen carinate; the sides much compressed ; the tail thin. T h e lateral line,
after making an arch over the eyes, runs straight along the middle o f the tail. T h e anus thoracic, between
the ventral fins.
T h e jin i . T h e dorsal rising from near the mouth, is continued to the tail ; the anal fin on the opposite
edge, joins also with the tail, but neither in such a manner as not to be distinguished from the caudal rays :
both are narrow, only widening a very little in the middle; the pectoral are situated near the branchial aperture,
short, distinct, rounded ; the ventral extremely small, and being partly adipose, the rays with difficulty
can be counted ; they cover the anus ; the caudal small and round.
T h e colour, as already remarked, dark on one side, and whitish on the other. T h e dorsal and anal fins are
o f a darkish brown, with a narrow white edging.

REMARKS.
T his species appears seldom, and is never brought to the European tables.
Another species still more different from the common sole, and which is found in abundance, will be
mentioned hereafter.
