Genus CHARADRIUS. 
The well-known Golden Plover of England may be regarded as 
the type of this genus as now restricted. About five species are 
known, all characterized by the flavour of their flesh and the great 
seasonal changes to which they are subject in summer and winter, 
and which have induced me to give two plates illustrative of them. 
One or other of the five species inhabit most parts of the entire 
globe, but are more abundant in the Old than in the New World.
