PLATE XLII. 
is stated to be of a large size, the upper-lip consisting of two 
l>ony parts, which may be protruded or retiaeted at the pleasure of, 
creature. In our fish there is no such contrivance in the upper 
; the mouth Is small, and the fish does not possess the faculty of 
®5£tending it to any very considerable length. Besides this, the fish is 
no means distinguished by such an uncommon degree of roughness 
‘'i the scales that invest the body, as to merit the appellation of “ cor- 
Pt>re aspero,” for they are comparatively smooth. In the French 
^‘^ition of Bloch’s Fishes, this kind is represented under the name of 
Plie rude. This figure shews the scales to be both large and 
’^°Ugh ; the head comparatively of a great size : the eyes large and 
Pfominent : opening of the mouth wide, and the jaws furnished with 
tnany teeth. 
Duhamel in his Traite des Peches, is the only author whp seems 
to have known this fish, and described it with accuracy. He notices 
^^0 strong affinity it bears both to the Sole and the Dab, observing 
^®ty justly, that the body is wider in proportion to Its length than that 
the Sole, and on the other hand of a more elongated form than 
^hat of the Dab : his figures are w’dl expressed, especially that of the 
'^PPer surface, in which the characteristic diminutiveness of the 
tttouth is well exemplified ; the curvature of the lateral line over the 
pectoral fin is indeed rather faulty, in being too widely extended in its 
Progress towards the head. Duhamel acquaints us that this is a scarce 
“Pecies on the coasts of France, being in many places entiiely 
^'iknown. 
In our fish the dorsal fin contains ninety rays : pectoral fin seven 
: ventral six rays : anal seventy-three rays : tail seventeen.
