Dr. J. Miiller (Wiegm. Arch.. 1841, p. 333) described two species, 

 Otaria Chilensis, and Arctoeq>halus Lamairii from Australia; but 

 0. Chilensis is probably 0. leonina, which is the only Eared Seal I 

 have seen from the west coast of South America, and the latter is 

 Arctoc^hahis lohafus. 



In the Leyden Museum (1845) there are four specimens of Pur- 

 Seal, all named Otaria ursina; they are of a black or dark grey 

 colour, with white tips to the hair and reddish under- fur ; the largest 

 is 4 feet long. One is from the Aleutian Isles, one from New Hol- 

 land, and two from the Creusette Isles. 



The Hair-Seals in the same museum, and the skull from Brookes's 

 museum, which I described as Arctoce^hal^^s lobatus, are called 

 0. Stelleri ; some are said to come from Japan and others from New 

 HoUand. 



In King's Narrat. Austral, ii. 414, 1828, I pointed out the dis- 

 tinction between the Fur-Seal of New South Shetland and the Hair- 

 Seal of Australia. 



The skull from the cabinet of M. Faujas, which Cuvier figures 

 (Oss. Foss. V. 222. 1. 18. f. 4), is much more like the skull of an adult 

 Aretoeephaliis than of Otaria juhata ; the outer and upper cutting- 

 teeth are scarcely larger than the others. 



There are ten skulls of this genus in the Paris Museum : — 



1 & 2. Adult and half-grown. From the Cape of Good Hope. 

 The palates become narrower behind. The front outer upper cutting- 

 teeth rather large ; grinders large, all except first and hinder upper 

 with two lobes (see Cuv. Oss. Foss. v. 221. t. 18. f. 5). 



3. Old skuU, from M. Parzudaki. 



4. From Australia, by MM. Quoy and Gaimard. 



5. Adult. From Port Jackson. Phoea cinerea. Very little different 

 from the adult from the Cape of Good Hope. 



6 <fe 7. Imperfect. King George's Sound. MM. Quoy and Gai- 

 mard (Cuv. Oss. Foss. V. 222). 



8. Adult. Auckland? The ' Zel^e,' 1841. 



9 & 10. From America, by M. d'Orbigny. The grinders larger, 

 more acute, and rather further apart. 



The Eared Seals (Arctoeephali) have been divided into Fur- and 

 Hair- (Eared) Seals by the sealers. A. Hookeri and A. lobatus are 

 called Hair-Seals because they are destitute of any under-fur ; but 

 this appears to be the case only with the older specimens ; for the 

 young of A. lohatus is said to be covered with soft fur, which falls 

 off when the next coat of hair is developed. The under-fur is well 

 developed in the adult specimens of A. ursinus and A. Delalandii and 

 the half-grown specimen oi A.nigrescens, and entirely absent in the 

 adult A. Hookeri and half-grown A. lobatus in the Museum Collection.
