THE THICK-KNEES. 127 



(Numenius), but they are g2nerally known by this title, and so 

 I retain it. 



Like the Bustards, the Thick-knees have a schizorhinal palate 

 and holorhinal nostril, and share with them another point, viz., 

 the absence of the hind-toe, or hallux. There are, however, 

 many anatomical characters in which the two groups differ, 

 and in many of these the Thick-knees show relationship with 

 the Plovers. In habits they are Bustard-like in many respects, 

 but their eggs are more like those of the Plovers, and they 

 never make any nest. 



There are four genera of Thick-knees, of \\hich Burhinus, 

 Esacns, and Orthorkamphus are Indian and Australian, while 

 the genus (Edicnemus is found all over the temperate parts of 

 the Palcearctic Region, and extends throughout Africa, India, 

 and the Burmese countries. It is also found in America from 

 Mexico to Amazonia and Peru.
