Habitat.- — Coasts of Japan and Formosa, north to Aomori. 



Head, -ii to 4i in length to base of caudal; depth, 3i to 3i. Eye, 12 

 to 14 in head; interorbital space, 13 to 14; distance from front of head 

 longitudinally to upper eye, 2i. Dorsal, 104 to 110; anal, S3 to S6. 

 Scales, from opposite gill opening, 92 to 96. 



Hook of upper jaw very long, extending around lower jaw to oppo- 

 site vertical from posterior margin of lower eye, or often considerably 



a Form of the European sole. Eyes on the left side. P. 9; V. 5; C. 16. Dorsal 

 and anal rays not counted, for the large numbers. Body 6 inches long, somewhat 

 round on the dorsal side, white below. ( Houttuyn. ) The enumeration of pectoral 

 rays prevents us from identifying Houttuyn' s description with this species. The 

 only soles in Japan with pectoral fins have the eyes on the right side.
