FLOUNDERS AND SOLES FROM JAPAN— HUBBS. 



471 



Color uniform dark brown, slightly mottled in the very young; 

 fins of eyed side dark, the vertical fins tipped with lighter; blind side 

 white including all the fins, the vertical fins darker distally. 



The young specimens are very readily separable from the young 

 of H. dubius, with which they were taken, not only by the fewer 

 fin rays, but also by the deeper body (ovate instead of elongate- 

 elliptical), by the less oblique mouth, and by the firmer flesh. 



Table of fin rays and gill-rakers in all the specimens, including the 

 type and the following paratypes: One from station 5008; four from 

 station 5009; three from station 5011; three from station 5012; one 

 from station 5013; all in Aniwa Bay, Sakhalin Island, dredged at 

 from 40 to 43 fathoms.

Protopsetta Schmidt, Pise. Mar. Orient., 1904, p. 230. 



Cleisthenes includes Protopsetta, each having been compared only to Hippo- 

 glossoides. 



Protopsetta was described as allied to Hippoglossoides, differing in 

 the insertion of the upper eye, which is placed on the upper outline
