_Geographic range._--Breeds from northeastern Siberia to northwestern Alaska. Winters south from the Malay area to Australia. In Micronesia: Mariana Islands--Rota; Palau Islands--Angaur, Peleliu; Caroline Islands--Ulithi. _Specimens examined._--Total number, 16 (4 males, 12 females), as follows: Mariana Islands, USNM--Rota, 1 (Oct. 20); Palau Islands, USNM--Peleliu, 14 (Sept. 6-14)--Angaur, 1 (Sept. 21). _Remarks._--The Little Stint is apparently a regular visitor to the Palau Islands and a less common visitor to the Mariana Islands. At Peleliu and Angaur the NAMRU2 party found these birds in small flocks of 10 to 15 at tidal flats and at inland ponds. On tidal flats the species appeared to remain apart from other kinds of shore birds, but at inland ponds the Little Stint was found in company with other species. On shooting into a mixed flock of shore birds at an island pond at Angaur, the writer secured specimens of this species and also of _Erolia acuminata_. =Erolia subminuta= (Middendorff) Least Sandpiper _Tringa subminuta_ Middendorff, Reise Nord. und Ost.
