Habits. Brown (Canoe and Camp Life, p. 123) gives the 

 following interesting note : — " In the small groves bordering the 

 Arapu River were numbers of birds of a kind allied to the Bell- 

 bird (Casmorhynclius carunculatiis) , whose singular call attracted 

 my attention. They utter a repetition of one metallic-sounding 

 note, not unlike that produced by repeated blows of a hammer on 

 an anvil, with great rapidity. A specimen of this bird which I 

 procured was submitted to Dr. Sclater, w'ho identified it as Cas- 

 vwrhgnchus variegatus. The peculiarity of this bird consists in 

 the extraordinary long black leather-like filaments hanging in a 

 fringe from the sides of its large mouth and throat. Its body is 

 white, head brown, and wings black. These birds are very nume- 

 rous from the Cotinga River to Roraima, but east of that river 

 only one or two individuals were met with."
