The South Pacific or Peruvian current striltcs the Soutli American 

 shores about Chiloe Island, Chile, a part being deflected northward 

 along the shores to Point Aguja, Peru, where it is deflected toward 

 the Galapagos Islands. This may bo considered as marking tho 

 Peruvic faunal area, thougii little is known of its Pyramidcllid fauna. 



Another part is deflected southward and sweeps the coast of South 

 America from Chiloe Island to the Strait of Magellan, This maps 

 the Magellanic faunal area. 



The South Shetland Islands and the territory to the south may be 

 considered as embracing the Antarctic faunal area in the restricted 



sense. 



GEOGRAPHIC TABLES. 



These tables are based upon tho specific cards, showing the geo- 

 graphic range of each species. A is used to denote its presence in 

 a faunal area; when a species extends over more than one faunal 

 area, the will appear in all the columns covered by its range. Sub- 

 species are given the same rank as species in the plotting of these 



tables.
