Hah. — River Gamma, Western Africa. Specimens in Mus. Acad. Philada. 



This large species resembles, in some measure, T. gidaris of Java, and also the 

 species immediately succeeding T. calurus, of Western Africa, but I have failed to 

 identify it with any other previously described. The cinereous or plumbeous 

 color of the breast varies in shade in different specimens, but in all is sufficiently 

 distinct, and usually forms a wide transverse band on the breast and upper part 

 of the abdomen. The feathers of the head are broad, and probably partially 

 erectile, and the curious hairs on the back of the head and neck are stron-lv 

 developed. 



Several specimens of this bird are in the Academy collection, all of which were 

 purchased from Mr. P. B. Duchaillu, who stated that he obtained them on the River 

 Camma, Western Africa. It is one of the largest and most handsome species of its 

 group. The figure in our plate represents the adult male of the size of life.
