33. LIMANDA ANGUSTIROSTRIS Kitahara, new species. 



Habitat. — Shores of Hokkaido. 



Head, 2| to -il in length to base of caudal; depth, 2i. Upper eye, 

 5 to 5| in head; snout, 5i to 5^; maxillary, 4^ to 4:^. Dorsal, 08 to 

 7-i; anal, 52 to 55. Fores in lateral line, 74 to 78. 



Head rather skMider, the snout produced, forming- a conspicuously 

 concavity in outline above upper eye. Upper eye a little posterior to 

 lower. Interorl)ital space, a high, sharp, naked ridge. Maxillary 

 reaching to anterior edge of lower eye, a little past front of orbital 

 cavity. Twenty-two to 24 teeth on blind side of lower jaw, 5 or 6 on 

 the other side; lU to 22 on l)lind side of upper jaw, none on the other.

tip reaching to, or a little past, angle of lateral line. Caudal very 

 slightly convex, angulated at tips of outer ra^'s. 



Scales large, embedded, and not imbricated; 13 to 15 scales between 

 middle of lateral line curve and back; 21 to 24 between angle of lat- 

 eral line and anal. In Z. iiol'oliaiin^ there are from 22 to 25 scales in 

 the same place on back, and from 30 to 36 on lower part of sides. 

 Scales every Avhe re cycloid except on posterior half of eyed side of 

 body. Height of curve of lateral line equal to length of upper orbital 

 cavit}' ; length of curve contained \\ to 1^ in head. 



Color uniform slaty ))rown, without definite markings. The unpaired 

 tins lighter; no color on blind side. 



This species differs from Lluianda yohohannv in having the snout 

 more pointed, the head more slender, the teeth smaller, the interorbital 

 space .sharper, higher and naked, the scales farther apart, more em- 

 bedded, and fewer of them counting trans\ersel3\ The ridge rumiing 

 from upper eye to lateral line is more rugose.
