-125- (20) RAPA AND VICINITY. TRERONIDAE. Ptilinopus huttoni Finsch. (Type loc.: Rapa.) Rápa: Hutton. The type, a female, collected by Capt. F. W. Hutton (1873, or earlier), appears to be still unique. It is the largest of the group, with a wing measuring 6.8 inches. --- The above is the only species actually recorded from Rapa, but J. V. Hall (Trans. New Zealand Inst., I, 1869, 128-134), who gave a general description of the island, added "there are a few fowls wild in the bush, some widgeon, and of course sea-gulls." A better knowledge of these birds is important! Some birds observed by Cook at sea are enumerated below, as they bear latitudes and longitudes nearer Rapa than to any other land area. Saw two Pintado Birds (Daption) Aug. 21, 1769, in 29° 44' S., and 148° 22' W. Saw one "Albetross" and "some smaller Sea Birds" Aug. 22, 1769, in 31° 3' S., 148° 00' W. Saw "several" Daption, Aug. 23, 1769, in 31° 6' S., 147° 29' W. Saw "several Albetrosses, Pintado Birds, and Sheer Waters; some of the Albetrosses were small, such as we usually saw off Cape Horn",
