Although I have previously admitted Cypsilurus atrisignis Jenkins as 
a distinct species, the chief character for its distinction seems to rest 
on the presence of the black round spot near the middle of its dorsal fin, 
Weber and Beaufort mention it and say of it "which may be wanting.” The 
presence of 56 to 62 scales and D. l3 to 15, compared with scales 50 to 55 
and D. 12 or 13, are hardly conclusive characters for distinction. Also 
40 predorsal scales for £. atrisigiis and 30 for the present species are 
hardly of importance,
