Members of the Genus Ptilopus. 569 



paper will therefore be found wanting rather on the side of 

 too little than of too much. 



In the cases of P. taitensis, Less. ( = P. purpuratus, Lath., 

 (/.'Finsch & Hartl.), P. fasciatus, auct. mult. ( = P. clemen- 

 tince, Jacq. & Pucher.), P. apicalis, Bp. { = P. fasciatus, jr., 

 Peale), P. pictiventris, Elliot { = P. fasciatus), P. neglectus, 

 Schleg. ( = P. rarotongensis, Hartl. & Finsch), and P. corriei, 

 Ramsay ( = P. tannensis, Lath.), some alterations in the 

 synonymy have been made. 



I arrange the eighteen Polynesian species of this genus 

 according to their geographical distribution, beginning with 

 the most eastern forms.
