One specimen has been reported previously from Laysan (Roths- 

 child, 1893) and two specimens and several sight records have been 

 reported from Midway Atoll (Bailey, 1956; Fisher, 1965). No sharp- 

 tailed sandpipers have been reported previously from either Kure 

 Atoll or Pearl and Hermes Reef. 



This species breeds in northern Siberia and winters from New 

 Guinea, New Caledonia, and the Tonga Islands south to Australia 

 and Tasmania (AOU, 1957). 



Dunlin Erolia alpina saktuilina 



A male dunlin (USNM 494127) was collected Mar. 15, 1965, by Clapp 

 while the bird was feeding in a small Sesuvium-boTdered pool on South- 

 east Island, Pearl and Hermes Reef. Two other dunlins, a male and a 

 female (USNM 493477, Jan. 12, 1964; USNM 496781, Mar. 28, 1965), 

 were collected on Sand Island, Midway Atoll. Lewis collected a fourth 

 specimen (USNM 496782), a female, Nov. 15, 1965, on Green Island, 

 Kure Atoll. The three specimens for which fat data is available 

 (494127, 496781, 496782) were all very fat. All specimens were subse- 

 quently referred to the race E. a. sakhalina by Laybourne. 



Sight records of dunlins have been reported previously from Sand 

 Island, Midway Atoll (Kenyon and Rice, 1957), and Laysan Island 

 (Rothschild, 1893-1900) in the Hawaiian Leeward Islands, and a speci- 

 men has been taken on Laysan (Bailey, 1956). The POBSP specimens 

 from Pearl and Hermes and Kure constitute the first distributional 

 records from those atolls and the birds collected on Midway are the 

 first specimens reported from there. 



The subspecies E. a. sakhalina breeds in northern Siberia and winters 

 south through Japan to India (Vaurie, 1965). 



Ruff Philomachus pugnax 



On Green Island, Kure Atoll, Dec. 11, 1963, Clapp saw a ruff feeding 

 at a rainwater puddle in association with golden plovers and ruddy 

 turnstones. A male (USNM 493332), collected on the beach the same 

 day, had heavy fat deposits and was in winter rather than prenuptial 

 plumage (see Kozlova, 1956). 



This species breeds in the Old World from northern Norway to 

 southern Siberia and is casual or accidental on St. Lawrence Island and
