While this genus is closely related to the preceding it shows a distinct 
development in the wing formation. 
The bill is similarly shaped, but longer and thinner, and the nostrils even 
more hidden. The legs show scutes in front, but no scutation behind. The 
feathers of the flanks are elongated into long filaments extending beyond the 
tail 
The wing in the female has the first primary longer than two-thirds the 
length of the second, narrow but scarcely falcate; the second has a pointed 
tip and the others are narrow. 
The male has a much more expanded bib with differently formed feathers. 
The wing has the first and second feathers more strongly falcate, the fourth 
and fifth subequal and shaved at the tips, but the sixth longest, the long 
secondaries equal to the third primary, which is very httle less than the longest. 
There are other developments of this group in New Guinea, and 
apparently Ptiloris has deviated the least from the parent stock, while the 
variations become more complex in New Guinea, and coloration of the females 
is the only guide to the relationships.
