of tlie small worms and seeds which constitute the food. It is rather bold, taking but little 

 notice of any one approaching it, and was never seen to perch on a tree. 



To Dr. Cabanis is due the credit of first referring this somewhat isolated genus of birds to 

 its correct position in the natural series. Swainson referred it to the Motacillina?, and Lafresnaye 

 and d'Orbigny classed it as an Anthiis. But there can be no doubt that, as shewn by Cabanis, 

 the proper place for the genus Centrites is the next to Muscisaxicola in the family Tyrannidcc^ 

 from which it is easily distinguishable by the Lark-like elongation of the hind claw. 



Our figures of this species are taken from two specimens, male and female, in Sclater's 

 collection, which were collected by Mr. H. Whitely at Tinta, in the highlands of Peru, in ]\lay 

 and Jime, 1868.
