50 BULLETIN 10 0, UNITED STATES NATIONAL MUSEUM 



A homogeneous group, often difficult of separation into well 

 marked species. For completeness I also include the single extra- 

 limital American species. 



As Cuvier includes but three species in Pempheris^ as P. totceay 

 P. Ttiangula and P. violucca^ the designation of P. oualensis Cuvier 

 1831 by Jordan, Tanaka and Snyder * is invalid.
