Easter Island lies in 27° 6' S. and 109° 1 7' W. ; it is very isolated, 

 distant about 2500 miles from the coast of Chile and nearly 

 1000 miles from Ducie, the nearest island of the Paumotu 

 Archipelago. A sn)all collection of fishes made at Easter Island 

 in April, 1911, by Professor Fuentes, is of considerable interest. 

 It includes examples of eleven species : seven belong to geneiu 

 or species of the tropical Pacific, thi"ee are new and are related 

 to species known from Norfolk Island or from New South Wales, 

 and one belongs to a new genus whose affinities are with TeqyJirceo'ps 

 of New South Wales and the southern coasts of Austialia. No 

 Chilean species are represented, and it is of interest to note that 

 in the case of Chilean genera, Acanthistius and Labrichthys, 

 relationship is with the Norfolk Island species and not with the 

 Chilean ones.
