Most of the later authors from Cuvier down to Day and Smith have included under 

 the synonymy" of this fish, Gerres equula of Temminck and Schlegel, 1 which is a distinct 

 Japanese species. 2 G. equula is, however, identical with G. erythroarum (Bloch). 3 It was 

 first described from Japanese specimens. Both these names therefore have been excluded 

 from the list of synonymy though they are found included in many of the previous lists. 



There are altogether three specimens, more or less damaged, measuring in length 

 76 mm., 77 mm. and 85 mm. without the caudal fin. They were all obtained at Satpara on 

 the 10th October, 1914. 



In all probability the fish is not a permanent inhabitant of the lake, but is a casual visitor 

 to the outer channel after floods. 



Distribution.— East coast of Africa, Eed Sea, seas of India, Malay Archipelago, the 

 Philippines ; the Fiji Islands and Japan.
