Sciaena distincta Tanaka (Dobuts. Zasshi, Tokyo, vol. 23, pp. 26, 

 27, 1916) and Sciaena aurea Tanaka (idem) both from Japan, I have 

 been unable to consult. 



Besides these little known species, I have arranged the following 

 tentative key to include the estabUshed species of this genus in the 

 Indo-Pacific.
