_Remarks._--Finsch (1875:41) recorded specimens taken by Tetens, Peters and Kubary at the Palau Islands. Coultas obtained one immature male at sea south of the eastern Caroline Islands at 1° 25´ N and 159° E on October 19, 1930. The Spectacled Tern ranges throughout the tropical Pacific, spending considerable time at sea, and probably reaches most parts of Micronesia in its travels. =Sterna anaetheta anaetheta= Scopoli Bridled Tern _Sterna Anaethetus_ Scopoli, Del.

Ranges west to Ceylon and north to Japan. In Micronesia: Palau Islands--exact locality not known; Marshall Islands--Bikar. _Measurements._--Four adult males from the Palau Islands have the following measurements: wing 246-254, longest tail feather 147-177, shortest tail feather 71-72, exposed culmen 40-44, tarsus 21-23; one adult female: wing 266, exposed culmen 40.5, tarsus 22.5. _Specimens examined._--Total number, 7 (4 males, 3 females) from Palau Islands, AMNH--exact locality not given (Dec. 20). _Remarks._--The Bridled Tern is known from the Palau Islands and from Bikar in the Marshall Islands. In Micronesia, the species apparently reaches the northeastern extent of its range. In the Palaus, Coultas found the terns on small outlying islands. He observed them to fly to sea early in the day and to return to the islands in the evening. Of the seven specimens obtained by him, two males and one female had enlarged gonads (Dec. 20). =Sterna fuscata oahuensis= Bloxham Sooty Tern _Sterna Oahuensis_ Bloxham, Voy. "Blonde," 1826, p. 251.
