Family RECUR VIROSTRIDiE.— The Avocets and Stilts. 



The Jiccxroirostridce, in addition to the features already men- 

 tioned (see p. 19), are characterized by the excessive length of 

 the legs, with very long slender neck and subulate, elongated 

 bill. The plumage has the same dense, soft character as that 

 of the Pkalaropodidce, Falicinie, and Longipermes.
