PLATE XCIV. 
introduced as a new British species in Dr. Turton’s edition 
tile Gnielinian Systema Nature upon the authority of the work 
^''st mentioned. This fish is certainly not specifically distinct from 
Common Flounder, Pleiironr.ctes flesus of Linnseus, but is one of 
varieties before enumerated. I'here is finally another variation of 
fish that merits particular remark, this is the reverse kind, in 
^hich the eyes and lateral line are situated on the left side instead of 
*‘^>5 right, as they appear in common. The reversed P'lounder is dc- 
®^rtbed by Linnaeus, Bloch, and a number of Ichtliyological writers, 
a distinct species. Pennant considers it a variety only, and we 
to be 
''“id of a 
*'oto 
fin. 
■corrected ; this relates to the extreme smoothness of the skin, which is stated to be 
all asperity either on tlie side line, or at the origin of tlie fins. If by this we 
toiderstaud the large subasperous scales which occur at the base of the pectoral 
“dd whicli descends in a linear series a short way down on each side tlie lateral line, as 
'i*® common Flounder, the observation is inaccurate. The skin Dr. Shaw observes, 
PPears to be only marked with scale-like reticulations without asperities, but in fact 
'hetely this appearance at the first glance, (except in those places where the true 
have been rubbed olf,) and tliis is owing to the transparency of the scales assf 
with the pale colour of the skin to which they are attached : when attentively 
■ttined the remaining scales are apparent; dicy are perceptible to the touch, and per- 
y visible willi the aid of a glass. Those scales have not the asperity that is to he 
^Pveted from the expression “ spinulh ad radices piimarnm,” adopted in the specific 
®^®oter of the common Flounder, neither have we scarcely ever observed the scales at 
^ ‘ise of Uie fins in the latter so spinous as to merit this appellation. Bat they are as 
in Pleui'onectes roseus, as general in tiie common Flounder, being of a superior 
the rest, a circumstance determined by lliose scales wliich sBll adhere to the ifkin, 
at wj. 
^ commencement of the lateral line, and at base of the pectoral fin; and even where 
Scales are obliterated, tlie region of the skin usually occupied by those larger scales, 
, ^*^ked with larger scale-like reticulations than tlie rest of tlie body, as is observable 
part of the common Flounder when deprived of the scales. There is besides a 
Slight . 
Appearance of asperity in the scales at the base of the tail, as in the co .ni.on
