KEY TO TII1<: WATER BIRDS OF IT.ORIDA. 



The eggs are buff white, mottled with brown and chocolate brown, 

 heaviest on the larger end. 



EREUNETES OCCIDENTALIS Lawr. 

 Western Semi pal mated Sandpiper. 



This species may he distinguished from E. pitsillus by its longer bill, which is oftentimes 

 1 .25 inches in length, while E. pitsillus rarely if ever has the bill one inch in length. Occasionally 

 examples of the Western Sandpiper have the bill less than one inch, and in such cases it is 

 almost impossible to distinguish them from the winter examples of E. pusillus j therefore it is 

 perhaps as well for the sportsmen to consider all of those birds having bills less than one inch 

 in length to be E. piisil/jis, and if it is important to have the identification absolutely accurate, 

 they could easily obtain the opinion of some professional ornithologist to settle such a fine point.

 on the East coast.
