 Myzopsetta Gill, Proc. Ac. Nat. Sci. Phila., 1864, p. 217 (ferruginea). 

 Limandella Jordan and Starks, new subgenus {yokoharax) . 



Teeth uniserial; lateral line with a distinct arch in front, and with- 

 out accessory dorsal branch; scales more or less imbricated, roug'h 

 ctenoid in the typical species but cycloid in one of the Japanese species; 

 vertebrte about 40. This genus is closely allied to Pseudopleuronectes^ 

 from which it differs onl}^ in the presence of an arch on the anterior 

 part of the lateral line. 



Color of e3^ed side Ijrownish; the blind side usuall}^ washed with 

 rusty red or with yellow in life.

 dentition. In Z/;«a;i6?rt proper, the teeth are bluntish conical not close 

 set, in an irregular row, which extends on the blind side of each jaw. 

 In certain Japanese species {LtinandelJ<() the teeth are broad, truncate, 

 evenh' set, restricted mainly to the blind side of each jaw.
