ALLIED in size and general appearance to the 

 Rhinoceros and two-horned Hornbills: colour black 

 with a blueish gloss: thighs, vent, and tail tawny- 

 white, but the latter crossed in the middle by a 

 very broad black bar: bill of similar size and pro- 

 portion to that of the Rhinoceros Hornbill, and of 

 a yellowish colour: the casque large, and shaped 

 like a crescent or boat longitudinally affixed by its 

 bottom to the ridge of the upper mandible: it is 

 not concave at the top, but flattened, and the two 

 ends rise up one before and the other behind the 

 base of the mandible, that in front somewhat ex- 

 ceeding the length of the other: the legs are short 

 and of a brown colour. Native of Java, where, 

 according to the account of a Dutch officer, com- 

 municated to Monsr. Levaillant, it frequents large 

 woods, uniting in troops in order to devour carrion.
