not differ materially from those of other members of the genus. The notes 
of all closely resemble each other.” 
In the third part (p. 351), after concluding the list, he added : “ I also 
observed that the Sittella leucocephala, from the neighbourhood of Port 
Denison, has a white band through the wing instead of a reddish or ‘ rusty-red ’ 
one, as described by Mr. Gould. In other respects it is almost exactly the 
same. I have only observed three specimens with this peculiarity, but am 
daily expecting a large series from Bowen, when I will make some further 
remarks, and give a fuller description of the bird; for the present I propose 
the name of albata for the Port Denison specimens, distinguished by having a 
ivhite hand, through the wing, commencing on the first primary and extending 
to the 9th quill." 
A full description was appended, but no further remarks have since 
appeared and recent collectors seem to have missed this species. In my 
“Reference List,” 1912, I considered this was the northern subspecies of 
N. leucocephala, differing from it in the same way that N. leucoptera differs 
from N. pileata. Inasmuch as intergradation, either in coloration or range, 
has not been proven I allow it specific rank, so that this item may be kept 
well in view.
