])()th falling short of the ])ase of the caudal. The shape of tlie caudal 

 can not ])e definitely determined; it probably was round posteriorly, at 

 least not deeply forked. Pectorals reaching- as far Ijack as insertion 

 of anal. Ventrals extending to a point midway between vent and anal. 



Color in spirits, uniform light yellowish })rown, except a subdued, 

 dusky dash across the distal end of pectoral, and an indistinct spot of 

 8amc color on the opercle near the base of pectoral. It was doubtless 

 nearly plain red in life, without spot or band. 



This seems to be the species recorded from Tokio l)y Steindachner 

 and Doderlein luider the name of Ap<)</(»i hlfasciatuK Riippell. But the 

 species shows no trace of dark bars and can not be RiippelPs species, 

 which came from the Red Sea. Doderlein records it under the manu- 

 script name of Apogon unicolor. which name Steindachner does not 

 adopt.
