When Gould introduced this species he wrote : “ Although I have placed 
this beautiful new species in the genus Ptilotis, I am by no means certain that 
I am correct is so doing ; for the bird possesses characters which ally it to at 
least three genera, namely, Stigmatops, Meliphaga and Ptilotis, while it also 
possesses characters peculiar to itself of almost sufficient importance to 
demand a distinct generic appellation.” 
Forty odd years afterward North, receiving information, eggs and nest 
from McLennan and Macgillivray indicating its likeness to Glyciphila, quoted 
Gould’s account and proposed a new genus, Trichodere , on account of the hair- 
like appearance of the feathers on the throat and fore-neck, without any further 
details. 
The bird is of medium size for a “ Ptilotis ,” larger than the Australian 
“ Glyciphila,” with flat head, long bill, long wings, long square tail and small 
legs and feet. 
The bill is longer than the head, nearly straight, culmen gently arched 
and tip depressed; nasal and ifictal bristles few and small; nasal groove 
long but not half the length of the bill, nostrils linear pervious, strongly 
operculate ; bill laterally compressed with little basal expansion; the inter* 
ramal space small and feathered, about one-third the length of the under 
mandible ; gonys almost straight, not marked, sloping a little anteriorly. 
Wing long, with the third, fourth, fifth and sixth primaries subequal 
and longest, the seventh a little shorter but longer than second ; the first 
primary short, more than half the length of the second, but less than half the
