Remarks

epipelagic, neritic-oceanic.
The species was descibed by Dana from the middle of the tropical South Atlantic.
For Björnberg (1963, p.61) the species were taken from 03°33'S, 33°32'W and 01°30'S, 34°16'W.
According to Vervoort (1965, p.193) the locality records from the Aleutians by C.B. Wilson (1950) require confirmation.
