Genus— ROGERS OENIS. 
Rogersornis Mathews, Austral Avian 
Record, Vol. I., pt. 5, p. 117, Dec 24th, 
1912. Type (by original designation) Ptilonorhynchus nuchalis 
Jardine and Selby. 
Regarding this genus I wrote “ Differs from Chlamydera in its stronger bill 
and stronger legs and feet, with longer wings and tad and proportionately 
longer first primary, while the third and fourth primaries are longest and 
subequal; in Chlamydera the third is longest.” 
This genus is separable from Chlamydera in that the females do not usually 
(if at all) acquire a nuchal crest. 
Large Bower-Birds with long bffls, long wings, long tail, long legs and 
feet and a hlac nape-band in the male only. 
The bill is almost as long as the head, laterally compressed with not much 
basal expansion, culmen arched, semi-keeled tip sharp, hooked, only a small 
notch posteriorly, lateral edges of upper mandible cmved ; nasal groove nearly 
one-third the length of the bill, the frontal feathers encroaching thereon but 
not reaching nor obscuring the oral apertm-es, placed anteriorly in the groove ; 
a few nasal bristles and minute rictal bristles ; the interramal space feathered, 
narrow, about one-third the length of the mandible, the gonys almost straight. 
The wing has the third, fomiih and fifth primaries longest and subequal, 
the sixth httle less, the second equal to the seventh, the first short but more 
than half the length of the third and equal to the long secondaries. The tail 
is long and square, the feathers broad. 
The legs are long and stout, seven or eight scutes anteriorly, bilaminate 
posteriorly; the toes long, the inner toe and claw shorter than the outer toe 
and claw and equal to the middle toe alone; claws long, curved and sharp ; 
the hind-toe with the claw long; the hind-toe and claw equal to the middle 
toe and claw.
