LIMANDA ASPRELLA, new species. 

 Plate 27, fig. 7. 



Type-specimen. — Cat. No. 75668, U.S.N .M. A male 185 mm. long, 

 from the fish market of Korsakov, Aniwa Bay, Sakhalin Island, col- 

 lected by the Albatross on September 25, 1913. 



This species differs from Limanda aspera and L. salcJialinensis in 

 the much smoother scales, only a few scattered ones with a single 

 median spine, while in the related species spines are present on most 

 of the scales and may be as numerous as 10. It also differs in the 

 more pronounced ridges of the head and in the projecting lower jaw. 

 It resembles L. aspera and differs from L. salcJialinensis in the arched 

 upper jaw of the eyed side; in having 18 pores in the suborbital branch 

 of the lateral line ; in the less compressed head ; and in the deeper body. 



Length of head, 0.27 of total length without caudal; depth, 0.53; 

 dorsal, 69; anal, 55; pores in the lateral line, 82. 



Head comparatively long, rather wide, its greatest width 0.09; 

 dorsal outline gently raised above eye ; ventral outline nearly straight, 

 the posterior end of mandible not prominent ; eyes equal in size and 

 on the same vertical; diameter of upper eye, 0.05; eyes separated by 

 a wide, raised interorbital; its entire width, 0.02; ridge not sharp, 

 but extended forward to form a high and prominent ridge on the 

 anterior margin of the lower eye; ridge behind upper eye sharp and 

 prominent; nuchal tubercle strong; ridge of preopercle strong and 

 angular; nostrils of eyed side as in L. aspera; the edges of the pos- 

 terior nostril of the blind side sharply indented ; region of snout sub- 

 quadrate in outline, its length from upper orbit, 0.05; upper jaw of 

 eyed side strongly curved anteriorly, the lower jaw projecting; the 

 teeth of the lower jaw visible, without the snout, when the mouth is
