PISCES THORACICI. PLEURONECTES. 
57 
The mouth, tongue, nostrils, junction of the dorsal and anal fins with the tail, are all as in the fish last 
described, but the lateral line rising nearer the mouth, forms a small arch before it becomes straight. 
The colour of the right side dark gray, with cross fillets of light brown from the front to the tail; the 
caudal fin spotted with brown spots with black edges; the left side light coloured. 
Length five inches. 
No. LXXIII. 
Pleuronectes oculis sinistris; cor pore lanceolato; lineis lateralibus duabus utriusque; pinnis 
pectoralibus carens ; pinna; dorsi, caudee , unique unites; cauda attenuata, acuta. 
The Pleuronectes with eyes on the left side; the body lanceolate; a double lateral line ; 
no pectoral fins; the dorsal, caudal, and anal fins united; the tail terminates in a 
sharp point.

Called by the Natives Jerree Potoo. D. 
The body lanceolate, much compressed; scales rather small, orbicular, imbricate, adherent, feel rough when 
stroked upwards. Of a dark colour on the left side, and white on the other. 
The head narrower than the body, ovate, compressed: the rostrum long, compressed. The mouth not 
terminal, as in the English sole, but at some distance from the extremity of the rostrum, on the verge of the 
abdomen ; not corrugated on the dark or left side, but rough with some small tubercles and pili on the white 
side. The tongue and teeth as in No. LXX. 
The eyes placed obliquely (though sometimes on an even line) between the lateral line and corner of the 
mouth, small, orbicular. The nostrils single, divided by a membrane: and situated between the eyes, or rather 
a little nearer the nose. 
The trunk. The back and abdomen carinate; the tail terminates in a sharp point. The principal lateral 
line commences at the middle point of the rostrum, and bending gently over the eyes, proceeds in a straight 
line to the tail. The second line is much higher, and runs parallel with the back. The anus is not in the 
carina of the abdomen, but a little on one side, giving place for a membrane which connects the ventral fin 
with the anal. 
The fins. The long dorsal rises at the centre of the rostrum; the anal near the branchial aperture: they are 
of equal breadth, and both are united with the caudal fin, in such a way as hardly to be distinguished, and, with 
the few caudal rays, composing the pyramidal sharp pointed tail. There are no pectoral fins; and the solitary 
ventral is connected with the anal. 
The colour of the left side blackish; of the right white; the dorsal, anal, and caudal fins, have a purplish 
cast. 
Length of the subject described, one foot five inches; greatest breadth, three inches two lines. 
REMARKS. 
This is the sole most common in India, and reckoned in delicacy even superior to that of England. The 
specimen drawn was of the largest size found at Vizagapatam; but, at Caringa, I have seen them considerably 
larger.
