 specimen procured by Dr. Preuss at Victoria in May, and its 

 occurrence in Benguela rests on one specimen mentioned by 

 Prof. Barboza du Bocage from Biballa, procured there by 

 Anchieta.

 records it from Grahamstown, Buffalo river and Kingwilliams- 

 town. In Natal these Wagtails are probably fairly abundant, 

 for although I did not meet with them, a friend of mine, Mr. 

 T. L. Ayres, has sent me several from Pinetown, where he then 

 lived, and the Messrs. Woodward have procured a specimen 

 at Eschowe in Zululand. Mr. T. Ayres found these Wagtails 

 in Natal frequenting the rocky streams generally in pairs, and
