THE BIRDS OF AUSTRALIA. 
“ Differs from S. m. viridior Mathews in being distinctly paler, with the under- 
surface almost white (including the throat), the band over the bill is light buff.” 
I, at the same time described : 
Sericornis magnirostris keri. 
“ Differs from S. m. viridior Mathews, in its darker colour generally and 
in lacking the buff band over the bill and on the throat : it is also larger. 
Bellenden Ker, Queensland. This form is so distinct that it is probably a 
species.” 
Campbell and Barnard recorded a bird as Sericornis ( magnirostris ) viridior 
from North Queensland writing : “ This large-billed Scrub- Wren was 
occasionally met with, especially in dense scrub where lawyer canes grow. 
When seen in the open for the first time the bird reminds one more of an Acanthiza 
than a Sericornis, but its comparatively powerful legs put it away. The male 
has a slightly more yellowish tone of plumage than the female.” 
And if the genus Megathiza be used, the names will be 
Megathiza magnirostris. 
Megathiza magnirostris magnirostris. 
Megathiza magnirostris viridior. 
Megathiza magnirostris howei. 
Megathiza magnirostris hunya. 
Megathiza magnirostris keri.
