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, J. c.) are as follows:—Total length 
about 1% 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. wnappendiculatus, 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. wnappendiculatus 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. ‘lhis was
