40 ART. 7. — S. TANAKA : 



high, with very broadly rounded outlines ; the caudal double 

 truncate, the angles scarcely produced ; first spine of first dorsal 

 strong, very rough, especially so above. Lateral line obsolete. 

 Scales with radial rows of prickles. Color brown ; both lips 

 black ; first dorsal blackish, second dorsal, anal and caudal 

 whitish ; free margin of these three fins black, the height of the 

 black parts being slightly less than the diameter of orbit ; the 

 black border of second dorsal and anal somewhat narrower 

 posteriorly. Base of the naked part of caudal narrowly black ; 

 first dorsal and pectoral dusky, free margin of the latter darker. 

 The part around the mouth posteriorly to the lips very broadly 

 whitish. Teeth white. 



The species can be at once distinguished from other species 

 by the black margin of second dorsal, anal and caudal. 



The type is the only specimen known. It was obtained at 

 Misaki in 1905. It is preserved in the museum of the Zoological 

 Institute with the Mus. No. 958. 



Mr. T. TsucHiDA, late Assistant in the Misaki Marine 

 Laboratary, who procured the specimen from a fisherman, informs 

 me that the whitish parts of the second dorsal, anal and caudal, 

 as well as the circumoral region, w^ere decorated with a bright 

 yellow color when the specimen was in life.
