Native names : " Orawei," Jobi {Rosenberg) ; " Orawai" at Ansus on Jobi Island (A. B. Meyer). 



Adult. Casque very high, conical, flattened posteriorly. Beak long and very stout. 

 Iris deep brown. Face, head, chin, throat, and upper half of neck deep blue, rather 

 paler on hinder part of neck. Face-wattles long, thin, pendent, and much swollen at 

 their base. Lower half of neck deep yellow or pale orange. Pear-shaped wattle 

 yellow, more or less suffused with blue. Naked sides of lower neck deep crimson. 

 On the occiput is a transverse patch of dull dirty orange. 



Plumage black and coarse; legs brownish grey; bill and casque black in most fully- 

 adult specimens, but some occasionally retain the greenish-horn coloured or pale olive 

 helmet of the immature bird. Legs dark olive. 



The measurements of the type (cf. Salvadori, I. c.) are as follows : — Total length 

 about If m., bill from gape 137 mm., tarsus 280 mm., nail of inner toe 70 mm. 



Young (full-grown). Plumage brown ; face-wattles absent ; naked parts dull bluish 

 green where deep blue in adult ; dull yellow instead of pale orange on lower half of 

 neck, and dirty red mixed with yellow on lower sides of neck. Casque dull green. 



Young (half-grown) similar to that of C. unappendiculatus, but casque bright green. 



Chick. Head and hind-neck pale rufous; body pale buff; back with five black bands 

 variegated with rufous; flank and thigh stripes broken up into irregular spots. 



This form differs from C. unappendiculatus principally in its more slender build and 

 its greater height, the greater extension of blue on the neck, the crimson lower sides 

 of the neck, and the very high casque. 



It inhabits the island of Jobi and perhaps also the opposite coast of Geelvink Bay. 



There occasionally occurs in this form, and probably also in all the other forms of 

 C. unappendiculatus, a curious melanistic variety, where nearly the whole neck is blue 

 and only a small spot of yellow remains at the base of the hind-neck. This was
