-16- variations in plumage dependent on age and sex. Much more material will be needed to unravel them, if indeed it can be done at this late date, as a number of them are supposed to be extinct (owing to pigs and cats, etc.), and only drawings or descriptions left by early voyagers are available for comparison. Almost all of the species are rare in collections, and the birds are difficult to find, even when known to be present.) Gallicolumba erythroptera (Gmelin). (Type locality: Moorea.) "Eimeo" = Moorea: Latham (ex Banks Collection). A specimen in the Leyden Museum, said to be of this species, may be the only specimen now extant. Gallicolumba eimeensis (Gmelin). (Type locality: Moorea.) Moorea: Latham. Described as different from erythroptera, but very likely will prove to be a plumage of it. Gallicolumba "pectoralis" (Ellis drawings, No. 71). Moorea: Ellis. No specimen extant, and identity not satisfactory. It is unlikely that two or three species of this genus ever occurred on one island, and it is more probable that immature and adult plu- mages are confused in these alleged species. Gallicolumba "leucophrys" (of Wiglesworth). Tahiti: Forster. Wiglesworth recognizes this as distinct, as based on Forster,
