orbit; jaws .siibequal, the lower slightly projecting. Edge of preop- 

 ercle linely serrated. Scales comparatively tirni and rough. Dorsal 

 spines rather strong, the third longest. Soft dorsal and anal reaching 

 equally far posteriorly when depressed, falling consideralily short of 

 base of caudal. Caudal subtruncate or slighth^ rounded. Ventrals 

 reaching anal opening. 



Color in life soiled brown, the sides with a greenish luster; no red 

 an3'where. Fins dull gray, washed toward the edges with inky black; 

 pectoral and caudal dirty yellowish; ventrals and anal most nearly 

 black. Length about 80 or DO millimeters. 



Shores of Kiusiu and Shikoku, in southern Japan; very common in 

 sandy bays. Known to us from about 50 specimens taken from the 

 harbor of Nagasaki and the neighboring bay of Mogi. 



The species is identilied by Schlegel and by Steindachner with Ajjo- 

 gon nigri2)innis, Cuvier and Valenciennes, from Pondicherry, but the 

 accounts given b}" Da}" of Cuvier's type show that this is a different 

 lish, with dark vertical bands and a black edge to the caudal.

 blunt, and rounded. Interorbital space convex; upper margin of eye
