Zealand group), we are not able to determine whether it is the 

 same species as the Otaria juhata, the Sea-Lion of the southern 

 end of the American continent, or whether it is the Sea- Lion 

 of the southern end of the African continent {Arctocephalus 

 Delalandii), or the Sea-Lion of the Northern Australian seas 

 {Neophoca lobatus). 



According to the observations of Dr. Peters, founded on the 

 examination of the typical skulls, Otaria ursina of Nilsson and 

 Otaria Lemarii of J. Miiller (Arch, f, Naturg. 1841, p. 334) 

 include the Arctocephalus Delalandii from South Africa and 

 A. cinereu^ of Australia. 



Otaria Stelleri of Schlegel (Fauna Japonica, t. 22. f. 55) in- 

 cludes both the Australian Eared Seals, viz. Arctocephalus cinereus 

 and Neophoca lohata ; and it is quite distinct from the Otaria 

 Stelleri of Lesson and J. Miiller, which is a combination of the 

 Sea-Bear and Sea-Lion of Steller (that is to say, Eumetopias 

 Stelleri and Callorhinus ursinus). 



The males of these animals are described as twice as long and 

 broad (that is, four times as large) as the females. This may 

 explain the difference in size of the skulls from the same 

 localities. 



The fur changes its colour as the animal grows, the young 

 being generally black; and the adult males and females also 

 differ considerably in the colour of the fur. 



The Eared Seals (Otariadse) must be considered a distinct 

 family from the Earless Seals (Phocidse). They have more 

 power of using their limbs like the more typical mammalia, 

 walking on them with the body raised from the ground ; they 

 rest with the hind limbs bent forwards. These habits are well 

 shown in Dr. Forster's figures, engraved by Buffon ; and they 

 have been verified by the study of the living Eared Seal in the 

 Zoological Gardens. Their scrotum and genital organs are ex- 

 posed as in the Dog. 



The Morse is intermediate between the Eared and the Earless 

 Seals in several particulars. It rests with its hind limbs bent 

 forwards, but it does not use its limbs so freely as the Eared 

 Seals. Some of the older naturalists correctly figured the atti- 

 tude of the Morse when at rest, as shown in my paper on the 

 figures of that animal (Proc. Zool. Soc. 1853, p. 112). Buffon, 

 misled by theanimal-preservers, figures it with the limbs extended 

 behind. Pander and D' Alton represent the animal and the ske- 

 leton in their proper position ; but they represent the skeleton of 

 the Eared Seal with its hind limbs extended backwards, though 

 the articulating surfaces of the bones of the legs should have 

 shown an anatomist that this is not the natural position in either 

 the Morse or the Eared Seal. Mr. Gould, in his * Mammalia of
