Conclusions. 



1. The fish-fauna of the Chilean coasts includes three elements: a) Sub- 

 antarctic species, distributed to about Chiloe; in the coastal waters mainly- 

 north of this region b) South Pacific species^, the chief part of which either 

 is confined to the Chilean waters or ranges to the coasts of New Zealand 

 and South Australia, c) Tropical Pacific species, which belong to genera of 

 mainly tropical distribution and either identical with species occurring northward 

 at the Pacific shores of tropical America or having their nearest relatives among 

 such species. 



2. The fish-fauna of Juan Fernandez consists for the largest part of 

 species, which are also found at the coast of Chile or are replaced there by 

 related forms, 



3. Most of the species belong to the above groups i b or i c, 



4. The number of endemic species is large; 50 % of the known species, 



5. Nearly all the Tropical Pacific species are also Chilean or — con- 

 cerning the endemic ones — closely allied to Chilean fishes (Nos. 1 — 7, 21, 

 23. 24—26). 



6. Of the South Pacific species a part is common to these islands and 

 Chile, many of the same ranging, however, westward at least to the coasts of 

 N. Zealand (Nos, 9 — 13). To this group can also be referred some of the en- 

 demic species (29, 35, 36). 



7. Another part of the South Pacific species has its nearest affinity 

 with forms from the western district of the South Pacific region, either in iden- 



^ To this group I in this connection also refer some species (e. g. Trachtirus trachurus) 

 the western range of which reaches beyond the Pacific Ocean.
