Pennant, in bis ' Quadrupeds,' describes an Eared Seal, rather 

 more than 2 feet long, the whole body of which was covered with 

 longish hair of a whitish or cream-colour ; it was brought from the 

 Straits of Magellan, and preserved in Parkinson's Museum on the 

 south side of Blackfriar's Bridge (see " Eared Seal," Pennant's 

 Quad. ii. p. 278). Dr. Shaw, in his ' General Zoology,' gave the 

 name of Phoca fiavescens to this species, and figured it (i. p. 260, 

 t. 73). 



This is very probably the young of the Hair-Seal of the Falk- 

 lands, desci"ibed by me as Arctocephalus Hoolceri, which is of a pale- 

 yellowish colour. Pennant does not mention the want of the 

 under-fur. 



Dr. Burmeister observes : — " We have in the Museum [at Buenos 

 Ayres] a young half-grown specimen [of Arctocephalus falklandicus} 

 nearly 3 feet long. From this I have taken the skull, of which I 

 send you a description and drawings " (Ann. N. H. 1866, xviii. 

 p. 99, t. 9. f. 1, 2, 3, 4). From the comparison of the figures, and 

 especially of the teeth and the form of the palate, with our older 

 skull of Arctocephalus Hookeri, I have little doubt that it is the 

 skull of a specimen of that species before the grinders were all de- 

 veloped. It is not the skull of Otaria jubata, which the other spe- 

 cimen he called A. falklandicus is, as proved by the form and 

 position of the hinder nasal openings. The figure of the young- 

 skull differs from the older skull of A. Hoolceri in the British Mu- 

 seum in having a notch in the middle, while the older skull of A. 

 Hoolceri has a conical prominence in the same place. Such dif- 

 ferences are found in skulls of Seals at different ages. 



The skull of the young animal described and figured by Dr. Bur- 

 meister as Arctocephalus falklandicus (Ann. & Mag. N. H. 1866, 

 xviii. p. 99, t. 9. f. 1 & 2), is probably the young skull of this 

 species. It agrees with it in the elongated form of the skull, and 

 in the large size and great development of the processes of the 

 orbits. 



Dr. Murie regards Otaria Philipjpii as founded on the skull of 

 this species (P. Z. S. 1869, p. 108). 



Mr. Allen, on the contrary, includes Otaria Hookeri as a syno- 

 nym of Otaria jubata. One could not have a better proof of the want
