Pseudorhombus misakius Jordan and Starks, Proc. U. S. Nat. Mus., vol. 31, 

 1906, p. 175, fig. 4. 



Three specimens from Shimizu, one from Nanao, collected by the 

 Albatross. 



This species differs from P. cinnamomeus in having cycloid scales 

 on the blind side, in the smaller mouth, and in the coloration; from 

 P. dupliocellatus in the larger scales (98 in P. dupliocellatus) ; from 

 P. ocellifer in the shorter, fewer gill-rakers; and from P. arsius 

 (Buchanan Hamilton), recorded from Japan by Snyder, 1 in "the lack 

 of a white bordered ocellus on the lateral line, fewer dorsal rays, and 

 a somewhat more slender body."

Genus XYSTRIAS Jordan and Starks. 



Xystrias Jordan and Starks, Bull. U. S. Fish Comm., vol. 22, 1902 (1904), p. 623. 



In the key to genera by Jordan and Starks, 2 the genera Xystrias and 

 Verasper are separated from Acanihopsetta by having the " anal spine 

 weak or obsolete." It is well developed in all three genera.
