WALEUSES. 
53 
specimens were presented by Sir G. Biulen-Powell, K.G.M.G., 
by whom they were obtained on a visit to the Commander Islands, 
Bering Sea. It may be observed that the coats o£ the stuffed 
specimens do not show any resemblance to the ^Cseal-skin o£ 
trade ; in the latter only the soft imder-tur is preserved, all 
the lono’ coarse hairs havino- been removed. The difference is

shown in the Index Museum. 
Intermediate in many respects between the Eared and the 
True Seals are the OdohfPnid(e, containing the two species or 
races of tlie Walrus, respectively inhabiting the North Atlantic

and North Pacihc Oceans. These animals lack external ears, 
but use their hind-limbs after the manner of the Eared Seals. 
In one respect, however, they are quite unique — namely, in 
the possession of long and powerful upper canine teeth, or 
‘‘ tusks,” which project downwards far below the lower jaw, 
and are used for ffghting, for climbing from the water on to 
the ice, and for digging on the sea-bottom for the shell-fish 
iind crustaceans on which these animals chiefiy live. Their 
range extends all round the North Pole, along the edges of 
the ice-fields. A complete specimen of the Atlantic Walrus, [CaseFX] 
Odohrenus rosmarus ( 642 ), is shown, but the Pacific ( 644 ) 
is represented only by skulls and tusks.
