Order XXXVIII. LIMICOIi^. (The Shore-birds.) 



This division of the old order of Grallm includes the allies of 

 the Plover and Snipe, as distinguished from the nearly related 

 Cranes and Rails on the one hand and the remotely related 

 Herons and Ibises on the other. Some of the external characters 

 of the group are the following. Tibia more or less naked below ; 

 legs long; hind toe free and elevated, often wanting. Head glo- 

 bose, abruptly sloping to the base of the bill ; completely feathered 

 (except in the male of Pavoncella) ; gape short ; bill weak, flexible, 

 more or less soft-skinned and sensitive at tip in most oases, adapted 

 for probing in the mud; nostrils slit-like, surrounded by soft skin. 

 Schizognathous ; precocial. 



The Limicoloe are all birds of small size, abundant on sandy 

 shores and in marshes. In spite of the difference in appearance 

 and habits, these birds have much in common with the gulls, in 

 their anatomy. (Lat., limus, mud; colo, I inhabit.)
