LIMICOLiE. 



The Knot passes the Japanese coasts on its spring and autumn 

 migrations from its arctic breeding-grounds to its tropic winter- 

 quarters, but apparently not in very great numbers. It has not yet 

 been recorded from Yezzo, but it is occasionally found in the Yoko- 

 hama market (Seebohmj Ibis, 1884, p. 34), whence I have an example 

 in the Pryer collection, and a second obtained from Mr. Owston. 



The Knot also passes the British coasts on its migrations to its 

 arctic breeding-grounds. It may be regarded as a circumpolar 

 species. 



337. TRINGA ALPINA. 



(DUNLIN.) 

 D-inffa alpina, Linneus, Syst. Nat. i. p. 249 (1766). 



The Pacific race of the Dunlin has been described as distinct from 

 the European race under the name of Pelidna pacifica (Coues, Proc. 

 Acad. Nat. Sc. Philad. 1861, p. 189). 



The Dunlin belongs to the section of cleft-toed Sandpipers which 

 have a great deal of white on the seventh, eighth, and niuth secondaries, 

 but little or none on the central upper tail-coverts. Its hind toe and 

 its black legs distinguish it from the other species in the section. 



Tringa alpina. 



Examples from East Asia and America are on an average slightly 

 larger birds, and may be recognized as subspecifically distinct under 

 the name of Tringa alpina pacifica.
