Forcipiger flavissimus JORDAN & MCGREGOR, Rep. U. S. Fish. Comm. for 

 1898 (1899), 279, Revillagigedo Archipelago. JORDAN & EVERMANN, 

 Fishes North and Mid. Amer., n, 1671, 1898. 



Forcipiger longirostris t JENKINS, Bull. U. S. Fish Comm. for 1902 (1903), 471 

 (Honolulu). 



Range. Polynesia, Hawaiian Islands. Revillagigedo Islands. 



We have examined 2 of the 4 specimens from Clarion Island on 

 which Jordan and McGregor based their species Forcipiger ( Chelmon) 

 flavissimus, thus separating the American specimens as a different 

 species from the Polynesian species, Forcipiger longirostris, and we 

 have compared with them specimens from the Hawaiian Islands. 

 There is no specific difference between the 2 sets of specimens. 

 The black triangle on the head occupies the same area in each, the 

 posterior edge of the soft dorsal is bordered with dusky, and the 

 black spot on the posterior end of the anal has the same shape arid 

 size, covering 7 rays in the larger specimens, only 6 in the smaller 

 ones. The following table shows, also, that the proportions and num- 

 bers of fin rays are the same in specimens from the 2 localities.
