being only slightly thickened, entirely covered with 
skin, and with a scarcely perceptible buckle, which 
externally appears like a small tubercle, and from which 
the groove in the scale runs in a forward direction. 
The anterior bend of the lateral line is comparatively 
low and long, as in the Brill, its height above the line 
as characteristic of the Brill, this form resembles the 
preceding one; but as in the Turbot and the preceding 
form the base of the ventral tin on the blind side is 
more than 8 % of the length of the body. 
The coloration of the Turbot-like Brill is olive- 
gray, with blackish brown, ocellated or simple spots

from the beginning of the lateral line behind the tem- 
poral region to the beginning of the straight part, is 
about a third of the length of this line, which in this 
form as in the Brill is equal to, or even greater than, 
the length of the middle rays of the caudal fin. In the 
other points that ive remarked in the preceding form 
on the body and the vertical fins, almost as in 
v. Weight’s figure of the Brill, though the large 
clouded spots are more indistinct. The white spots 
at the bases of the dorsal and anal fins, as well as on 
the lateral line and the operculum, are also preserved 
in this form. 
an intermingling of the characters of the Turbot with 
those of the Brill that we can hardly regard these two 
chief species of the genus as widely separate. 
In whatever way we choose to explain these two 
forms — whether as hybrids, which seems most likely, 
or as varieties of another signification — they show such
