Pale brown generally, under surface with silvery sheen 
punctuated with deep or dusky brown. Dark brown blotch below each eye. 
Vertical fins whitishj dorsal terminally above with dusky blotohij caudal 
with gray blotch terminally on lower lobe, another paler and smaller 
medially, besides still third basally; at base of upper caudal lobe short 
oblique well contrasted blackish bar. Paired fins largely blackish, though 
pectoral usually, or at least in largest specimen of series show whitish 
transverse band at basal third of fin, also one or more large darker 
nebulous areas or blotches on remaining outer portions of fin. 
Pinang, Singapore, East Indies, China, Western Australia, 
J^lenesia. Compared with Bleeker’s rather crude figure of Exocoetus 
nigripinnis my specimens differ in many ways. He shows the vertical fins 
blackish, though the caudal with a slightly paler oblique bar from the base 
of the upper lobe down to the lower lobe? the position of the ventr'i>l fin 
also more advanced so the depressed fin would fall well short of the 
caudal base. The white pectoml band of some of the larger young specimens 
seem to suggest the possibility of the identity of Cypselurus arcticeps. 
Exocoetus nigripennis Valenciennes is described with D. 12, A, 
10, paired fins black, caudal yellowish, body above brown, below white.
