Specific Characters. — First primary longest, but nearly equal to second; 

 third about as much shorter than the second as the fifth is less than the 

 fourth; the fourth seven tenths of an inch shorter than the third. Tail 

 very narrow, the outer feathers white ; hinder claw one fifth longer than the 

 toe. Length eight inches and one fifth; carpus to tip four inches and 

 seven tenths; beak three fifths of an inch long by three tenths broad; 

 hind claw half an inch to two fifths of an inch long;. 



This bird was thought by Pallas and Latham to be a variety of 

 A. calandra. It is, however, a very distinct species, and the rounder 

 form of the beak, the much slighter figure, the more pointed wing, 

 and the difference in comparative length of the fourth primary, remove 

 it altogether from that bird. The late Mr. Blyth considered it to be 

 a typical Calandrella.
