516 IMPBNNES SPHENISCUS 



This genus contains four ■well-marked species found on the coasts 

 of South America and South Africa, extending northwards to the 

 Galapagos in the Pacific and to Eio Grande do Sul in southern 

 Brazil on the west and to South Angola on the east side of the 

 Atlantic. One species extends to the Falkland Islands and South 

 Georgia ; but curiously enough no member of the geiius is found on 

 Tristan da Cunha. 



Only the species here described is found along the African 

 coasts.
