 The nails small and often quite rudimentary, especially those of

 elongated, compressed, and curved. 



The Eared-Seals, commonly called Sea-Bears or Sea-Lions, are 

 widely distributed, especially in the temperate regions of both 

 hemispheres, though absent from the coasts of the North Atlantic. 

 As might be inferred from their power of walking on all fours, 

 they spend more of their time on shore, and range inland to greater 

 distances, than the true Seals, especially at the breeding time, 

 though they are obliged always to return to the water to seek their 

 food. They are gregarious and polygamous, and the males are 

 usually much larger than the females, a circumstance which has 

 given rise to some of the confusion existing in the specific deter- 

 mination of the various members of the genus. Some of the 

 species possess, in addition to the stiff, close, hairy covering common 

 to all the group, an exceedingly fine, dense, woolly under fur. The 

 skins of these, when dressed and deprived of the longer harsh outer 

 hairs, constitute the " sealskin " of commerce, so much valued for 

 wearing apparel, which is not the product of any of the true Seals. 

 The best-known species are 0. stelleri, the Northern Sea Lion, the 

 largest of the genus, from the North Pacific, about 10 feet in 

 length ; 0. jubata, the Patagonian or Southern Sea Lion (Fig. 272), 

 from the Falkland Islands and Patagonia ; 0. californiana, from 

 California, frequently exhibited alive in menageries in Europe ; 

 0. -ursiiia, the common Sea-Bear or Fur-Seal of the North Pacific, the 

 skins of which are imported in immense numbers from the Prybiloff 

 Islands ; 0. pusilla, from the Cape of Good Hope : 0. forsteri and
