  1. Values for the holotype and specimens from off Japan based on Masuda et al. (1986), vertebral count for holotype confirmed from radiograph; values based on specimens from the Indian Ocean from original data (Discovery Sta. 54007, 54009, USNM 122665) or based on Kotthaus (1969)aFrom the original description (Whitley, 1941)
  2. bAnomalously high interorbital width for single large specimen (75.2 mm SL) recalculated here as %HL from Kotthaus (1969: 39, published values in %SL)
