Zealand group), we are not able to determine whether it is the 
same species as the Otaria jubata, 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. cinereus of Australia. 
Otaria Stellert of Schlegel (Fauna Japonica, t. 22. f. 55) in- 
cludes both the Australian Hared Seals, viz. Arctocephalus cinereus 
and Neophoca lobata; 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, Humetopias 
Stellert 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 (Otariade) must be considered a distinct 
family from the Harless Seals (Phocide). 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 Hared 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 Hared 
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 the animal-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
