This genus appears to take a situation intermediate between 

 Motacilla and Anthus on one side and Alauda on the other. It 

 differs from the former in the strength and horny nature of the 

 bill, in which it approaches to Alauda ; but the bill is longer 

 than in the latter genus, straight and decidedly notched. In the 

 degree of enlargement and the curvature of the claw of the pos- 

 terior toe it also holds an intermediate situation. The legs are 

 comparatively robust, and the size of the tail is different from the 

 allied genera.
