At one time I thought that it might be a peculiarity of the young state, as it had up to that time only been observed in skulls of half-grown animals. It occurs in half-grown specimens of _Euotaria nigrescens_; but the skulls of the very young specimens of this Seal in the British Museum have the front edge of the hinder nasal opening truncated and slightly arched in form, with well-developed square palatine bones united by a central suture just as in the adult, but broader and straighter. It was this observation that induced me to return to my original opinion, that the skull which I had at first regarded as a young skull of _Arctocephalus monteriensis_ (Proc. Zool. Soc. 1859), and then as a separate species under the name of _A. californianus_ (Cat. Seals and Whales, p. 51), was only a monstrosity of _A. monteriensis_, as I did in the Ann. & Mag. Nat. Hist. 1866, xviii. p. 232; and I am now induced to believe that _Arctocephalus schisthyperoës_ is only an imperfectly developed skull of _A. antarctica_. Dr. J. R. Forster, in Cook’s voyage in 1775, observed the Eared Seal at the Cape of Good Hope, and called it _Phoca ursina_. Believing it to be the same as the Sea-bear he had observed in New Zealand, Thunberg, in his list of Cape Mammalia in the third volume of the ‘Transactions of the St. Petersburg Academy,’ iii. 322, notices this animal under the name of _Phoca antarctica_ (see Fischer, Syn. Mam. p. 242). Dr. Peters has applied the name of _Otaria pusilla_ to this species, believing it to be the _Petit Phoque_ of Buffon, which has been named _Phoca pusilla_ by Schreber, and had before been named _Phoca parva_ by Boddaert. Buffon says that it came either from India or the Levant; but it is not by its description to be distinguished from a young specimen of almost any of the species. It is as likely to have come from the Falkland Islands as from the Cape, as the French had traffic with Les Iles Malouines, as they call them. M. de Buffon describes a small Eared Seal, which he calls a “second Phoque” (vol. xiii. p. 341, t. 43, where it is named “le petit Phoque”), which, he was assured, came from India, but very probably came from the Levant; and he considers it adult, because it has all its teeth. It is only one-fifth of the size of the Seal of the European seas (Hist. Nat. xiii. p. 344). He further speaks of it as “le petit Phoque noir des Indes et du Levant” (p. 345). It is evidently a young Eared Seal. The figure is probably from the skin, with the bones of the toes and jaws, presented to the cabinet by M. Mauduit (mentioned at p. 433. n. 1273), and said to have come from India. The specimen Buffon figured, then being in the Paris Museum, was thus described by Cuvier (Oss. Foss. v. p. 220):—“Cet animal a deux pieds de long; ses oreilles sont grandes et pointues; son pelage est fourré, luisant, d’un brun noir très-foncé et a sa nuance blanchâtre. Le ventre seul est brun-jaunâtre.” The teeth show that it is young.
