Red Sea, Arabia, Madagascar, India, Ceylon, East Indies, Philip- 

 pines, Indo-China, China, Formosa, Japan, Korea, Melanesia, Austra- 

 lia. In my "Fishes of Oceania" I placed Sillago gracilis Alleyne and 

 Macleay as a synonym, though, as McCulloch has placed it with 

 Sillago maculata Quoy and Gaimard; besides as the original figure 

 shows a dark mark at the base of the pectoral, it had best remain with 

 Quoy and Gaimard's species.
