Comments: Has been regarded as conspecific with Arctocephalus phillipii by some authors (e.g., Hall 1981). Considered a distinct species by Jones et al. (1992), Wozencraft (in Wilson and Reeder 1993, 2005), and Reeves et al. (1992).
Gardner and Robbins (1998) pointed out that Otoes and Halarctus are the earliest available generic names for northern and southern fur seals, respectively; they have petitioned the ICZN to preserve the generic names Callorhinus and Arctocephalus for these seals.
