open flats and grass-lands, where they are found in flocks of 

 from six to twenty in number. They run with great swiftness, 

 and have much the appearance of Burchell's Courser, accord- 

 ing to Mr. Ayres, who also says that when they rise, their 

 flight resembles that of a Pratincole, and they utter much the 

 same stridulous note of alarm. Their food consists principally 

 of beetles and other small insects, on which they become very 

 fat. 



THE BLACK-BREASTED DOTTERELS. GENUS EUDROMIAS. 



Eudromias^ Brehm, Vog. Deutschl. p. 544 (183 1). 



Type, E. vior melius (Linn.). 



The single representative of this genus is a more heavily- 

 built bird than the species of Algialitis and Oxyechus, but it 

 has the shorter bill of the latter birds, and holds an intermediate 

 position between them and the species of Ochthodromns. Its 

 peculiar coloration in the full plumage, and its comparatively 

 shorter tarsi distinguish it, and the bare part of the tibia is not 

 so extended as in the genus ^gialitis,
