THE BIBDS OF AUSTRALIA. 
little variable, but my specimens are very dark above, unspotted and tail 
unbarred. All the specimens of boohook I had examined had the tail-feathers 
more or less barred, and De Vis’s description gives the latter feature, but 
his second bird, a female, agrees with my type male. The interposition of 
this form almost between boobook and mixta, both comparatively light forms, 
is very interesting and emphasizes my contentions regarding “islands” on 
the Australian continent. Here we have practically an island form confined 
to the Bellenden Ker “ Island,” though this is not separated by “water. The 
nearest bird as regards the upper coloration is Ninox goldiei of Sharpe 
from Goodenough Island, Solomon Group. 
Spiloglaux novcBseelandim macgillivrayi Mathews. 
Cape York Peninsula. 
I have a nice series from this locality and find they approach the preceding 
in the lack of bars on the tail, but are very much lighter in coloration both 
above and below. 
North commented thus, with regard to 8. n. lurida : 
“ This diminutive representative of N. boobook, in the tropical scrubs and 
mountain ranges of North-eastern Queensland, is in contradistinction to its 
northern and north-western ally N. ocellata mixta), distinguished by the 
intensely rich colouring of its plumage. This is more apparent on the throat, 
upper portion of the breast, axillaries, and under- wing coverts.” North did 
not then know the present subspecies, or he might have remarked on the 
peculiarity of this more northern form. The series show the constancy of 
the subspecies. 
Spiloglaux novceseelandicB everardi, subsp. n. 
Central Australia. 
Specimens from Central Australia differ from typical birds in being paler 
and in having the throat and face white to a larger extent. This has been 
previously indicated by North, Keartland and White, so that I here furnish 
a name for this form. The type was collected by Captain S. A. White in the 
Everard Ranges, Central Australia, on the 2nd August, 1914. 
Spiloglaux novmseelandice albaria Ramsay. 
Lord Howe Island. 
I have given Ramsay’s description and notes concerning this form. It 
is comparatively near boobook, though Ramsay said it wasn’t, and is quite 
unlike typical novcBseelandice, notwithstanding his remarks. It is, peculiarly, 
a light island form and not a dark one, and a specimen has been in the 
British Museum for over fifty years, packed away amongst the boobook birds. 
Its white face is rather distinctive.
