Mus. Novit., no. 1248, 1943, p. 8 (Guam, Palau, Ponapé, Kusaie). _Geographic range._--Breeds in northern parts of the Northern Hemisphere. Winters to Southern Hemisphere. In Micronesia: Mariana Islands--Guam, Rota, Saipan; Palau Islands--Angaur, Peleliu, Caroline Islands--Yap, Ulithi, Truk, Lugunor, Nukuor, Ponapé, Kusaie; Marshall Islands--Jaluit, Rongelab, Mille, Majuro, Wotze, Likieb, Bikini. _Specimens examined._--Total number, 36 (17 males, 16 females, 3 unsexed), as follows: Mariana Islands. USNM--Guam, 7 (Oct. 10-26)--Rota, 2 (Oct. 20, Nov. 2); AMNH--Guam, 4 (Mar. 22, 27, Aug. 18); Palau Islands, USNM--Peleliu, 1 (Sept. 8); AMNH--exact locality not given, 3 (Dec. 8); Caroline Islands, USNM--Truk, 1 (Dec. 22); AMNH--Ponapé, 4 (Dec. 16)--Truk, 4 (Feb. 5, 7, July 14)--Kusaie, 7 (Mar. 10-30); Marshall Islands, USNM--Bikini, 3 (Feb. 26, Mar. 4). _Weights._--The NAMRU2 party obtained the weights of four males taken at Guam and Rota as 77-99 (92) and one female from Guam as 90. These birds were obtained in October and November. _Parasites._--Wharton and Hardcastle (1946:316, 320) list the following chiggers (Acarina) from the Turnstone from Guam and Peleliu: _Neoschöngastia carveri_ and _N. strongi_. Wharton (1946:174) records also _Acariscus anous_ from the Turnstone at Guam. Uchida (1918:489) records the bird louse (Mallophaga), _Colpocephalum pediculoides_, from this bird at Ponapé. _Remarks._--The Turnstone is a regular visitor to Micronesia and to most other parts of Oceania. As pointed out by Stickney (1943:8), the material obtained by the Whitney South Sea Expedition yields evidence that the population which winters in Oceania is as widespread as that of _Pluvialis dominica fulva_ but less abundant. The writer's observations at Guam, Ulithi and the Palaus are in agreement with this evidence. Stickney suggests that the reason the Turnstone was not recorded by the Whitney South Sea Expedition in eastern Polynesia was because of "a tendency of the turnstone to hug the continental coasts more closely, avoiding extensive overseas migrations."
