210 MAMMALIA—MORSE. 
victory somewhat resembles the chirping of a cricket. These animals are 
chiefly found on the islands in the vicinity of Kamtschatka, from June to 
September ; after which they remove, some to the Asiatic, and some to the 
American coast. On -Behring’s Island they are so numerous as almost to 
cover the whole shore; but it is a singular fact, that they uly frequent that 
part of it which lies towards Kamtschatka. 
Ursine seals live in families, each male being surrounded py from eight 
to fifty females, whom he watches with the most vigilant jealousy, and 
treats in the most tyrannical manner. They are of an irritable disposition, 
and have frequent battles. So tenacious are they of life, that they will live 
a fortnight after receiving wounds which would be speedily mortal to other 
animals. 
THE WALRUS, OR MORSE. 
THE name of sea cow, or sea horse, by Which the walrus is most gene- 
rally known, has been very wrongly applied; since the animal whieh it 
denotes has not the least resemblance to the land animals of that name: 
the denomination of sea elephant, which others have given it, is much bet- 
ter imagined, as it is founded on a singular and very apparent character. 
The walrus, like the elephant, has two large ivory tusks, weighing from 
ten to thirty pounds each, which shoot from the upper jaw; its head also is 
formed, or rather deformed, like that of the elephant, and would entirely 
resemble it in that part if it had a trunk; but the walrus is deprived of that 
instrument, which serves the elephant in the place of an arm and hand, and 
has real arms to make use of. These members, like those of the seal, 
are shut up within the skin, so that nothing appears outwardly but its hands 
and feet: its body is long and tapering, thickest towards the neck: the 
1 Trichecus rosmarus, GmMEL. The genus T'richecus has two upper and no lower inci- 
sors ; two upper and no lower canines; ten upper and ten lower molars; incisors small, 
deciduvus ; superior canines or tusks large, fees than the head, compressed laterally ; 
molars cylindneal, crown truncated obliquely ; body elongated; head round ; muzzle large ; 
no external ears; tail very short; fore feet like fins, with five toes; hind feet horizontal ; 
toes enveloped in the skin.
