356 | CONCLUSIONS. 
In Callorhinus ursinus the female, as we observe, attains only 
half the length of a male. The weight of a fullgrown female being 
less than one sixth that of a full-grown male. 
The losing of hair when the animals grow very old, is very 
striking in both Odobaenus rosmarus and in Odobaenus obesus. 
Food. The food of all Pinnipeds consists of mussels, and other 
mollusks, especially, however, of all kinds of fish, but that they 
are not averse to cetacean flesh, may be proved by the following 
fact: Mr. Brown says of Odobaenus rosmarus: “1 have only to add 
that whenever it was killed near where a whale’s carcass had been 
let adrift, its stomach was unvariably found crammed full of the 
krang or flesh of that Cetacean” (Auten, Host. N. Am. Pinan. 
p. 135). Humetopias Stellert occasionally eats birds (Ibid. p. 274). 
Breathing. — Even in seals and sea-lions it may be occasionally 
observed that they “blow like a whale’; I myself saw it more than 
once, when the animals lay with their nose at water level, or when 
they appeared on the surface after having remained under water 
for a long time. It is sufficiently known that the average time 
these animals remain under water is eight or ten minntes, but they 
have also been observed lymg quite still on the bottom for more 
than three hours. I read in Mr. Auuen’s work (p. 180) that also 
walruses “blow not unlike a whale”. 
Lecretion. — The emitting a very strong odour is also known 
in Pinnipeds. KrascHEentnikow says of Callorhinus ursinus: “Such 
as are old, or have no mistresses, live apart; and the first that 
our people found upon Behring’s Island were such old ones, and 
all males, extremely fat and stinking’ (ALuEN, p. 342). Of Hume- 
fopias Stellert Cuoris reports: “L’odeur quils répandent est insup- 
portable. Ces animaux étaient alors dans le temps du rut” (ALLEN, 
p. 254), and of Poca foetida KUMLIEN asserts: 
“It is only the adult males (called 7guk, = Stinker, by the Eskimo) 
that emit the horribly disagreeable, all-permeating , ever-penetrating 
odor that has suggested its specific name. It is so strong that one can 
smell an Eskimo some distance when he has been partaking of the 
flesh; they say it is more nourishing than the flesh of the females, 
and that a person can endure great fatigue after eating it. If one 
of these Tigak comes in contact with any other Seal meat it will 
become so tainted as to be repulsive to an educated palate; even the | 
atluk of the Tigak can be detected by its odor.” (AnuEN, p. 624). 
Respecting the foetid odour emitted by this species, Dr. Rink 
observes as follows: ;
