TOL. 48. 



The anal spine is very slightly developed in the young, absent in 

 the adult. 



Three of the specimens collected by Jordan and Snyder at Aomori, 

 Japan, show a remarkable variation of the anterior rays of the 

 dorsal fin; they are not deflected onto the blind side as normally in 

 PleuronicMTiys, but are borne on a thick hook, which is extended 

 nearly straight forward. This variation may have been produced dur- 

 ing the translation of the eye. These specimens, and to a lesser 

 degree other specimens from the same locality, show a more or less 

 complete coloration of the blind side. 



Measurements in hundredths of length to base of caudal. The 

 first specimen is from Swatow, China.
