Wattled and Spurred Plovers, the former having a lappet of 

 bright coloured skin on the face, while the spur, in those 

 genera which possess it, like the Nile Plover (Hoploptenis 

 speciosus), is often quite a formidable weapon. In England, 

 however, none of these forms have as yet made their appearance 

 in a wild state, and all our species are unarmed and un- 

 decorated. 



THE GREY PLOVERS. GENUS SQUATAROLA.

Type, S. helvetica (Linn.). 



In the first group of Plovers, to which the genus Squatarola 

 belongs, the inner secondaries are always very long and pointed. 

 They are all birds of rapid flight, and very different in the 

 latter respect from the slower and more flapping Lapwings. 

 The Grey Plover, which is the only species of the genus 

 Squatarola, puts en a black breast in summer, like the Golden 

 Plovers (Charadrius], but it is easily distinguished from the 

 latter by the presence of a small hind- tee.
