26 BIRDS OF ILLINOIS. 



The single North American species of this subgenus differs con- 

 spicuously from the Plovers usually included together under 

 jEgialitis in the broad, lengthened tail, and, so far as coloration 

 is concerned, in the ochraceous rump and the pair of black 

 bands across the breast. It may be remarked, however, that 

 coloration alone is of slight importance as a character in this 

 group. 



The Old World species appear to belong here rather than with 

 true ^EgicMtis, namely, Cka/rad/riM^ tricolla/ris VIEILL., of South 

 Africa, and O. nigrtfons CUVIER, of Australia. The former is 

 much like a miniature Killdeer Plover, having two black pec- 

 toral bauds, like O. voclfern* (though their relative width is 

 reversed, the posterior one being broader) ; the proportions and 

 details of form are quite the same, but the rump and upper 

 tail-coverts are concolor with the back. The Australian species 

 agrees essentially with the above in size and proportions, but 

 has broader and acuminate rectrices, and the tail is more nearly 

 even, while the plumage is handsomer and more varied than in 

 any other species of the group, the scapular region being adorned 

 with a patch of rich maroon-chestnut, the upper tail-coverts 

 rufous-chestnut, etc.
