a strong curve in front. Gillrakers few, short, compressed, wide 

 set. Vertebra, 16+34. Largest of the flounders. This genus con- 

 tains the well-known halibut; abundant on both coasts of the North 

 Atlantic and of the North Pacific.

23. HIPPOGLOSSUS STENOLEPIS Schmidt. 



Hlppoglossm stenolepis Schmidt, Fauiie Mer. Och. Jap., 1903, p. 19 (Okhotsk Sea, 

 name only); Pise. Mar. Orient, 1904, p. 224 (Gulf of Aneva). 



Hahitat. — Okhotsk Sea, probably south to Hokkaido. 



Head, 1.5 in length; depth, 3.3; eye, 8.2 in head, 2 in snout; man- 

 dible, 2.8 in head; least depth of caudal peduncle, 1.6 in depth of 

 body; dorsal, 95; anal, 71; pectoral, 17; caudal, 16; branchiostegals, 6. 



General shape of body as in Ilippoglofisus hippoglossus^ the head 

 more blunt and convex; eyes equal in size, on right side, and sepa- 

 rated b}" a space li times the length of the upper eye; teeth large, in 

 two rows on upper jaw, in a single row on sides of lower jaw and in 

 double row in front; scales everywhere cycloid and covered by skin; 

 at the posterior end of some of them a rough bon}" plate, which is 

 easily detached; no supplementar}^ scales. 



Origin of dorsal opposite front of pupil, its greatest height one-third 

 of depth of body; length of pectoral equal to postorbital part of head; 

 caudal somewhat concave; ventral reaching beyond front of anal. 



Color, olive brown with bright spots corresponding to the bony 

 plates. 



This species difi'ers from H. hipj)ogloss)/s in the construction of its 

 scales and in having a smaller numl)er of fin ra3^s and gillrakers. 

 Length of specimen described, lt)l7 millimeters. (Schmidt.) 



It is known to us solely from Schmidt's account. It seems to replace 

 the common halibut in the Sea of Okhotsk.
