Hob. Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu. 



Obs. Another bird, the generic position of which is to us uncertain. After 

 careful examination, however, it appears most properly belonging as we have 

 placed it. This species is strongly characterized by the bright rufous of its 

 head above and tail. 



This bird is named in honor of Col. Geo. A. McCall, late Inspector General in 

 the Army of the United States, in token of respect for hib extensive and varied 

 acquirements as a naturalist, and of personal friendship.

Dab. Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu. 



Obs. This species differs in colors from any other known to me, and the 

 transverse bands of the inferior surface of the body are, so far as I know, pecu- 

 liar to the present bird only of this genu^. 



This remarkable bird is dedicated to Professor Spencer F. Baird, of the Smith- 

 sonian Institution, one of the most eminent American naturalists, as a remem- 

 brancer of our long continued and pleasant friendship.

Hub. Liberia. Rev. Wesley Johnson; St. Paul's river, Dr, MacDowall; 

 Moonda river, Mr. Du Chaillu. 



Obs. Though this singular species has long been in the possession of the 

 Academy, I have not found it described. It appears to be somewhat similar to 

 Laniarius peli, Bonap. (Consp. Av. p.* 360), but not identical, so far as can be 

 ascertained from the short description as cited. This bird can be easily recog- 

 nized by the white spots in front of the eye, the feathers of which are erect and 

 tipped witli black, and by the yellow spots at the tips of the wing coverts and 

 secondaries.
