Back brown, sides below and under surfaces silvery white. 
Iris silvery white. Dorsal and caudal brown, former with large black 
spot^ Well contfS-cted, anteromedially on fin. Pectoral with membrane0 
deep to dusky brovmish, blackish terminally. 
Red Sea, Natal, India, East Indies, Philippines, China, Polynesia, 
Hawaii. The largest species in owt collection. It always shows a uniform 
pectoral in combination with the black spot on the dorsal. In this way it 
may be easily distinguished from Cypselurus spilopterus. 
I am unable to find any characters on which to separate 
Exocoetus cyanopterus Valenciennes. The distinctions given by Barnard 
as A. 9 or 10 for C. bahien sis and A. 11 or 12 for C. cyanopterus are 
overreached by materials I have studied.
