GENERIC CHARACTERS. 







top, extends over the eyes, and returns to the base of the maxilla by a moderate curve. Nostrils 

 basal, exposed. Wings long, reaching a short distance beyond the upper tail-coverts. Tail long, 

 much rounded ; two median rectrices twice the length of the rest. Tarsi short, stout, covered 

 with strong scales. Toes stout. Claws strong, curved. 



Genus V. ANTHRACOCEEOS. 

 Head covered by a lengthened crest. Skin around eyes and space at base of mandible nude. 

 Bill long, abruptly curved at tip. Casque covers two thirds the length of maxilla, is compressed 

 laterally, extends over the head to above the eyes, and curving forwards returns to culmen by 

 an acute angle. Nostril on top of maxilla, at base of casque, small, round, exposed. Wings 

 moderate ; secondaries as long as primaries ; third primary longest. Tail long, much rounded. 

 Tarsi short, stout, covered with strong scales. Toes short, stout. Claws curved, strong. 



Genus VI. CBANORKHINUS. 



Skin around eyes and on throat bare. Bill long, rather slender, graduating to a sharp 

 point, crossed at base by several prominent transverse ridges. Casque high, upright, keel- 

 shaped, swollen posteriorly, flattened anteriorly, covering nearly half the maxilla; curves 

 gradually from the highest point of the anterior terminus, backwards to centre of the head. 

 Wings ample ; secondaries nearly as long as the primaries. Tail long, rounded. Tarsi and 

 toes short, stout, covered with strong scales. Claws stout and acute. 



Genus VII. PENELOPIDES. 



Head covered by a lengthened crest. Bill rather short ; base covered by a plate, on the 

 maxilla with broad transverse grooves, on the mandible with narrow diagonal grooves. Casque 

 low, compressed laterally ; rises at base and extends for two thirds the length of maxilla, and 

 terminates abruptly at a right angle to the culmen. Bare skin around eyes and at base of 

 mandible. Wings long ; fourth primary longest ; first primary falcate. Tail long, slightly 

 rounded. Tarsi and toes short, stout, covered with strong scales ; outer and inner toes united 

 at base. Claws strong, curved, acute. 



Genus VIII. CEEATOGYMNA. 



Occiput crested. Side of face around the eye, throat and front of neck, with the exception 

 of a narrow line in the centre covered with short feathers, and large gular pouch naked. Bill 

 rather stout, very short. Culmen curved, especially at the apical third. Gonys nearly straight 

 until within a short distance of the tip, where it curves downward. Casque very large, flat on 

 its anterior face, keel-shaped on top, and swollen towards its posterior margin ; highest in front, 

 it curves rapidly downwards to above the eyes ; several longitudinal grooves run along the sides. 

 Wings ample, rather short. Tail long, much rounded. Tarsi and toes stout, short, strong. 



Genus IX. SPHAGOLOBUS. 

 Head covered by a long bushy crest. Skin around eyes, sides of face, throat, and gular 

 pouch naked. Bill rather short, stout, pointed. Maxilla curved ; gonys nearly straight. Casque 

 very large, swollen laterally and rounded on top ; rises from the maxilla about one third its length 

 from the tip at a rather acute angle, curves backwards over the head, and returns to the maxilla 

 at a sharp angle. Wings rather long. Tail long, slightly rounded. Tarsi short, stout. Toes 

 rather long, stout. Claws strong, acute.
