In Micronesia: Mariana Islands--Guam, Rota, Saipan, Agrihan; Palau Islands--Angaur, Koror; Caroline Islands--Yap, Ulithi, Truk, Faraulep, Lamatrek, Ponapé, Kusaie; Marshall Islands--Jaluit, Mille, Arhno, Majuro, Maloelab, Wotze, Likieb, Ailuk, Bikini. _Specimens examined._--Total number, 47 (23 males, 20 females, 4 unsexed) as follows: Mariana Islands, USNM--Guam, 13 (May 21-29, Sept. 19-27, Oct. 10, 23),--Rota, 2 (Oct. 23, 25); AMNH--Guam, 4 (April 23, Aug. 16); Palau Islands, AMNH--exact locality not given, 1 (no date); Caroline Islands, USNM--Ulithi, 3 (Aug. 20, 22); AMNH--Truk, 1 (June 25),--Ponapé, 1 (Dec. 15),--Kusaie, 19 (Feb., Mar., April 1-10); Marshall Islands, USNM--Bikini, 3 (Feb. 26, 28, April 28). _Weights._--In 1948 (1948:53) I listed weights of two males from Guam as 175 (May) and 109 (September); weights of two females from Guam were 175 and 192 (both in May). These data were obtained by the NAMRU2 field party. _Parasites._--Wharton and Hardcastle (1946:296, 316, 318) list the following chiggers (Acarina) from tattlers taken by NAMRU2 collectors at Guam and Peleliu: _Neoschöngastia bougainvillensis_, _N. ewingi_, _N. carveri_, and _N. namrui_. Wharton (1946:174, 175) records the chiggers, _Acariscus pluvius_ and _A. anous_, from tattlers from Guam. It is not certain from which species of _Heteroscelus_ these chiggers were obtained. _Remarks._--Records indicate that the American Wandering Tattler is a regular visitor to eastern Micronesia, and that it only occasionally reaches the Palau Islands in western Micronesia.
