-107- (9) ISLANDS SOUTH OF LINE OR FANNING GROUP. CAROLINE ATOLL. PERISTERIDAE. ?Gallicolumba, species. Bennett found (April, 1835?) "The inland thickets contained a great number of small pigeons, with white head and neck, and the rest of their plumage of a rich brown colour." There is little or no doubt as to the genus, but the species may never be known. About 1869, four men were fattening hogs on cocoanuts at Caroline Atoll, for the Tahiti market, and the hogs are likely to have exterminated these fround pigeons. No pigeons were noted by the 'Eclipse' party, in May, 1883, and probably they were exterminated long before this time. There is a possibility, however, that remnants of the species may still exist on some of the islets forming this atoll. ?RALLIDAE. ?Fulica or ?Porphyrio. Bennett found a bird "resembling a coot" on the coast. ?IARIDAE. "Seagull." The 'Eclipse' Party, May, 1883, recorded "two species" of "Seagull", but they may have mistaken tropic-birds for gulls, as they recorded no species of Phaethon. STERNIDAE. Gygis alba pacifica (Lesson).
