DISCUSSION OF SPECIES AND THEIR DISTRIBUTION.

lire about sixty. The specialized scales of the lateral line extend far out upon the caudal 

 fill. Ou the bliud side the lateral Hue is little couspicuous, the scales very slightly special- 

 ized, aud it becomes obsolete in the region where, upon the colored side, the curve is located. 

 The scales extcud far out upon the caudal fin, but are not preseut upon the other fius. 



Head very short, its length (18) contained about five times and one-half in the total. 

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

 vertical, and the maxillary exteudiug very slightly behiud the anterior margin of the orbit. 

 The teeth are inconspicuous, apparently in two rows, stronger and more numerous on the 

 bliud side, barely discernable iu upper jaw, absent elsewhere iu the mouth. 



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

 and e(iual to tliat 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 outliue trenching upon the 

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

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



The dorsal tin begins over the posterior part of the pupil of the upijer 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 (S) is equal to 

 half the length of the head. The anal is inserted uudcr the axil of the jjectoral, and its 

 height is about the same as that of the dorsal. 



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

 caudal. It is broad, fan-shaped, acutely convex iu 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 fcrnajinea, the right fin 

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



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

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



Radial formula: D. 63-GS; A. 54-56; C. 18; P. 7; V. 6; lateralline about 88; 27 in curve. 



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

 shape very unlike that oi Limanda ferruginea of our own coast and Limanda plutessoides of 

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

 both lateral, it resembles considerably the species mentioned above.
