DISCUSSION OF SPECIES AND TIIKIK DISTRIBUTION. 



429 



are about sixty. The specialized scales of the lateral line extend far oul upon t ho caudal 

 tin. On the blind side the lateral line is little conspicuous, the scales \ ery slightly special 

 i/.ed, and it becomes obsolete in the region VI here, upon t he colored side, t he curve is located. 

 The scales extend tar out upon the caudal fin, but are not present upon the other tins. 



Bead very short, its length (IS) contained about five limes and one-half in the total. 

 The snout is very short (2), one-fiftieth of the total, and the mouth is small, its clefl sub 

 vertical, and the maxillary extending very slightly behind the anterior margin of the orbit. 

 The teeth are inconspicuous, apparently iu two rows, stronger and mure numerous on the 

 blind side, barely discernable in upper jaw, absent elsewhere in the mouth. 



Eyes large, prominent; their diameters (7) greater than the length of the maxillary (6) 

 and equal to that of the mandible (6). They are very closely set, the interorbital space 

 marked by a knife-like edge of bone. The upper eye, in its outline trenching upon the 

 dorsal outline of the head, is almost directly above its mate. Together they occupy nearly 

 three-fourths of the width of the head at the perpendicular passing through their centers. 



The dorsal tin begins over the posterior part of the pupil of the upper eye. Its rays 

 are long, widely separated, and with their tips protruding beyond the membrane, giving to 

 this, as also to the anal, a ragged, irregular appearance. Its greatest height (8) is equal to 

 half the length of the head. The anal is inserted under the axil of the pectoral, and its 

 height is about the same as that of the dorsal. 



The length of the caudal (20) is equal to one -fifth of that of the body, without including 

 caudal. It is broad, fan-shaped, acutely convex in outline. The distance of the ventral 

 from the snout (28) is about one third the length of the base of the dorsal. The arrange- 

 ment of these fins upon the ventral keel is much as in Limanda ferruginea, the right tin 

 being almost upon the median line. The pectorals are normal. 



The color is grayish brown, mottled with darker patches. There is a conspicuous black 

 blotch upon the outer rays of the caudal on either side. 



Radial formula: D. 63-6S; A. 54-56; 0.18; P.7; V.6; lateral line aboutSS; 27 in curve. 



The extreme brevity of the snout and the elongate-elliptical form of the body render its 

 shape very uulike that of Limanda ferruginea of our own coast and Limanda platessoides of 

 t he Eastern Atlantic Iu its general appearance, however, except that the ventrals are not 

 both lateral, it resembles considerably the species mentioned above.
