and the Antilles to South America, reaching extreme Southern South 

 America and the Falkland Islands. 



Bonaparte's, or the vvhite-rumped Sandpiper was obtained by the nat- 

 uralists of the Princeton Expeditions and the individuals are cited below 

 in detail. 



In writing of the White-rumped Sandpiper Mr. Barrows says : "In 

 small squads or large flocks at the same times and places as the following 

 species." (Barrows, Auk. I. p. 314, October, 1884.) The "following 

 species " here referred to is Heteropygia maculata, which the same writer 

 speaks of as being present throughout the year save in the period between 

 the middle of November and the middle of January. This is not a little 

 remarkable, as both kinds of sandpipers are known to breed in the far 

 North and during the months of May, June and July.
