ARCTIC WALRUS. 237 
to a siibspiral twist : there is also a difference in 
the position of the tusks in the two animals ; those 
of the variety figured in Captain Cook's voyage 
curving imvards in such a manner as nearly to meet 
at the points, while those of the former divaricate. 
These differences appear very striking on collat- 
ing different heads of these animals. Something 
may, however, be allowed to the different stages 
of growth as well as to the difference of sex. In 
order that these differences may be the more 
clearly understood, we have figured both varieties 
on the annexed plates ; and, as a farther illustra- 
tion of the subject, we shall give, in the celebrated 
navigator s own Avords, the description of a herd 
of Walruses on a floating mass of ice in the above- 
mentioned latitude. 
They He, in herds of many hundreds, upon 
the ice; huddling one over the other like swine; 
and roar or bray very loud ; so that in the night, 
or in fog-gy weather, they gave us notice of the 
vicinitv of the ice, before we could see it. We 
never found the whole herd asleep, some being 
always upon the watch. These^ on the approach 
of the boat, would wake those next to them ; and

the whole herd would be awake presently. But 
they were seldom in a hurry to get away, till 
after they had been once fired at. Then they

lost them, though mortally wounded. They did
