FLOUNDERS AND SOLES FROM JAPAN— HUBBS.

Albatross station 5031, Yezo Strait. 

 Albatross station 5067, Suruga Gulf, Hondo. 



This species seems to represent L. bilineata in northern Japan, and 

 differs from that species as follows: 



1. Higher, sharper interorbital. 



2. Usually larger eyes. 



3. Upper profile of head straighter. 



4. Smaller scales, pores 95 to 99 rather than 79 to 95. 



5. Anterior nasal flap shorter, reaching only one-half the distance 

 to posterior nostrils, nearly reaching posterior nostril in L. bilineata. 



6. The mucous pores of the head are much more pronounced. 



7. One or two instead of three or four series of scales on anterior 

 border of orbits. 



8. The scales are smoother, and of a different character, the 

 roughest with 2 rows of spines, 2 in the apical row, and 5 or 6 in a 

 row parallel with this; L. bilineata has a similar apical row, and 

 about 10 to 15 in the other row; 



9. Head more acute; 



10. Fewer gill-rakers, 3 or 4 + 7 to 9 in L. bilineata.

A minute rudimentary gill-raker is sometimes present on the 

 upper limb of the firs-t arch, but is not included in the table. 

 The fin formula agrees with that of L. bilineata.
