island of the Paumotu archipelago, naturally makes it a matter of great interest 
to enter upon the relations of the fish fauna. KENDALL and RADCLIFFE 
remark that »the fauna of Easter Island seems to be different from that of its 
nearest neighbor, Manga Reva (Paumotus) and appears closest to that of Nor- 
folk Island». REGAN points out that it is not related to the Chilean fauna 
and also calls attention to the resemblance to the fauna of Norfolk Island. 
My own studies have led to the result that I entirely agree with REGAN 
that there is no element related to the Chilean or, as far as is known, the 
South American Pacific fauna. On the other hand, from a zoogeographical 
point of view I can find no reason to proclaim a closer and restricted rela- 
tionship with the coastal fauna of the distant Norfolk Island. 
If we examine the Easter Island species with regard to their general 
distribution, we can divide them into the following groups’: 
A. Species of wide distribution, outside the tropical Pacific at least 
also found in some part of the Indian Ocean. 
Myripristis pralinius C. V. Platophrys mancus Brouss. 
Kyphosus cinerascens Forsk. Parupeneus trifasciatus Lac. 
Cheilio inermis Forsk. Xanthichthys lineopunctatus Hollard. 
Thalassoma purpureum Yorsk. Belone platyura Bennet. 
» umobrostygma Rupp. Diodon holacanthus Lin. 
Salarias arenatus Bleek. 
Bs Poly mesianusmecies. 
Flolocentrum punctatisstmum C. V. Paumotu, Samoa, Hawaii. 
Anampses pulcher Regan. Tahiti. 
Alticus variolosus C. V. Samoa, Guam, Tonga, Hawaii. 
Pomacentrus tnornatus Regan. ?Samoa. 
Decapterus sancte-helene C. V. Distribution? 
Cy Hawairanyspecies, 
Caranx cheilio Snyder. Teuthis umbra Jenkins. 
Kellogella oligolepis Jenkins. 
Dee Nortolteistand species: 
Trachypoma macracanthus Giuth. 
E. Endemic species and their allies. 
Bathystethus orientale Regan, related to B. cultratum Forster, of Norfolk 
Island. 
Kuhlia nutabunda Kend. & Radcl., related to K. humzl7s De Vis, Queens- 
land, Fiji, and to AK. sandvicensis Steind., Hawaii, Society I. 
1 I don’t consider the two species determined by KENDALL .and RADCLIFFE as JZona- 
canthus cirrifer Schleg. and Gymnothorax dovii Ginth., the identification of which seems to be 
very uncertain (cfr. REGAN, p. 373).
