Remarks .—On 24 April 1866 , the Italian warship Magenta was at 10°44’S , 104°28’E , some c .35–40 nautical miles from Christmas Island in the Indian Ocean ( Giglioli 1870 , 1876 ). Giglioli originally identified the specimen as a juvenile Ascension Frigatebird F. aquila (Linnaeus, 1758) but it was re-identified as F. andrewsi , probably by Salvadori, after the species was described by Mathews (1914) . Photographs and measurements of the bill and wing confirm the re-identification (I. A. W. McAllan pers. comm.).
