of the belted variety, and the identification was confirmed through speci- 

 mens secured by Professor Hine on the following day. He also took 

 another set of four eggs about two weeks later from a nest in a similar situa- 

 tion, but some four hundred yards north of the first discovered site. From 

 the advanced stage of incubation he was sure that the eggs belonged to a 

 different pair of birds. 



The question of the validity of the two forms of Piping Plovers is 

 still open for discussion. The finding of this nest makes it certain that 

 the breeding ranges of the alleged subspecies overlap considerably.
