GEOGRAPHICAL DISTRIBUTION. 



The Phocidce are found along the seashores of all parts of the 

 temperate and colder j)ortions of the globe, but those of the 

 Southern Hemisphere belong (with one exception) to different 

 genera fi^om those whose habitat is in the Northern Hemisphere, 

 and for the most part to a distinct subfamily not elsewhere rep- 

 resented. All the members of the so-called " subfamily" Steno- 

 rhynchince are confined to the south-temperate and Antarctic 

 Seas. The Phocince, on the other hand by far the most nu- 

 merous division of the family are strictly northern, only two 

 or three of the species reaching the middle-temperate latitudes. 

 Of the Cystoj)horincVj consisting of two genera, one genus {Cys- 

 topliora) is boreal, and the other (MacrorJiinus) has one repre- 

 sentative on the coast of Lower California, and another on the 

 islands and shores of the southern i)art of South America, South 

 Africa, and the Crozet and Desolation Islands in the Indian 

 Ocean. Of the Phocince, one species, the Monk Seal {Monachus 

 albiventer), is found on both shores of the Mediterranean Sea, in 

 the Adriatic and Black Seas, and at the Madeira and Canary 

 Islands, and probably on the neighboring Atlantic coast of
