32 otariam:. 



the Otaria falklandica of Shaw nor the O.falMandica of Burmeister 

 as Dr. Peters supposes, as I have shown above. In this paper he 

 removes Otaria falklandica (that is, nigreseens) from the subgenus 

 Phocarctos, to which he referred it in his first paper, and places it in 

 his subgenus Arctophoca. 



1. Arctophoca Philippii. Chilian Fur-Seal. 



Otaria (Arctophoca) Philippii, Peters, Monatsbericht, May 1866, 



p. 276, t. 2 (skull), September 1866, p. 671. 

 Otaria Hookeri, var., Murie, P. Z. S. 1869, p. 108 ! 



Inhab. Juan Fernandez Island (Philippi ; in Mus. Berl.). 



Above black-grey, more greyish yellow on the head and neck, 

 brownish black beneath ; the base of the limbs of a rusty brown, 

 shining ; lips and lower jaw principally rusty brown ; hair of beard 

 in six rows, partly black, partly quite white, partly black with 

 white base. The outbristling (prominent bristly) pointed hairs are 

 rusty brown at the base, black at the end, on the back mostly with 

 very short rusty-yellowish points, and on the head and neck with 

 somewhat longer ones. On the sides of the belly the ends of the coarser 

 pointed hairs are either uniformly brownish black, or are very short 

 rusty-red ones. The thick under-hair is rusty red. The hairs on 

 the upper surface of the neck are 22 millims. long ; those on the 

 middle of the back 18, and those on the middle of the belly 11 to 

 12. The dense short hair on the back of the hand extends only to 

 the middle of the same, not extending to the ends of the fingers, the 

 ends of which are furnished with very small nails. In like man- 

 ner, the very similar hair on the back of the foot does not ex- 

 tend to the last " Phalangen ? " of the middle toe. The nail of 

 the large outer toe is small, flat, and cut off short outside ; that 

 of the fifth inner toe is a little larger and cut off abruptly on the 

 inner side. The very developed long nails of the three centre toes 

 are of the form of keeled teguke, and remote along their whole 

 length by the emarginations of the skin of the foot. The skin- 

 flaps of the foot are equally long ; and usually those of the centre 

 toes are much smaller than the side ones, of which the outside 

 one (the great toe) is the broadest. The scrotum, under the anus, 

 is bare. — Peters, I. c. p. 277. 



I have not seen this skull ; but I believe the alteration Dr. Peters 

 made in his second paper is a mistake. The figure of the skull of his 

 Otaria Philippii has no resemblance to the skull of my 0. nigreseens. 

 It is more nearly allied to the skull of O.Stelleri from California, agree- 

 ing with it in having a vacant space with a pit in the bone between the 

 fourth and fifth upper grinders on each side, looking as if a grinder 

 had fallen out and the cavity had been filled up. The subgenus 

 Arctophoca of Dr. Peters's first essay, not as modified in his second 

 one to contain O. falMandica (nigreseens), chiefly differs from Gill's 

 genus Eumetopias (which was formed on my description and figure of 

 the skull of O. Stelleri or californiana) in the fifth upper grinder 

 not being so far back, but in a line with the back edge of the orbital
