(Horsfield). 
Coloured Figures.—Dresser, ‘ Birds of Europe,’ vol. ix, pl. 712; 
Seebohm, ‘ Ibis,’ 1893, pl. 5. 
Breydon, in Norfolk, has yielded a specimen of the Old 
World, or Siberian Pectoral Sandpiper. The bird, an adult, 
was shot on August 29th, 1892 (‘ Ibis,’ 1893, pp. 181-185, 
plate 5). A specimen, said to have been obtained in 
Yarmouth in September, 1848, is preserved in the Norwich 
Museum. 
This species breeds in Eastern Siberia, and on migration 
in autumn passes along the eastern side of the Asiatic 
Continent and the Malay Archipelago, reaching as far as 
Australia, and New Zealand.
