DESCRIBED by Labat and others as of the size of 

 a turkey, and entirely of a black colour: the beak 

 both in shape and colour seems considerably allied 

 to that of the Rhinoceros Hornbill, but the process 

 or casque runs strait forwards instead of reverting 

 at the tip as in that species. A specimen is said 

 to have been in the Ley den Museum which differ- 

 ed in having the abdomen and vent white, the head 

 somewhat crested, and the tail tipped with white. 

 Native of Africa.
