MOTACILLINiE. 231 



Southern India, most of this tribe having a wide geographical dis- 

 tribution, and I have little doubt that it will hereafter be found 

 more widely dispersed. 



2nd.— Titlarks. 

 The next group may be specially designated as the Titlarks, in 

 which the plumage of the young birds resembles that of young 

 Larks, the feathers being more on less pale edged.

 approximating it to Macronyx of Africa.
