Mr. J. H. Gurney^s Notes on 
M, from Amboyna. Nearly adult, but retains tbe tail- 
featbers of tbe immature plumage unmoulted ; in these tbe 
inner webs of tbe lateral rectrices are marbled, not barred ; 
it also retains tbe primaries and tertials unmoulted, and in 
these tbe inner webs are transversely barred, but in the 
secondaries, which are newly acquired, they are unbarred; in 
other respects tbe plumage agrees with G, except that the 
dark shaft-marks are rather more widely spread on the crown, 
and are also apparent on the back of the head. 
N, from New Guinea. This is an interesting specimen, 
as it is moulting, and the dress which it is losing and that 
which it is acquiring are both adult j some of the new pri¬ 
maries are transversely barred on their inner webs, whilst 
the remaining old primaries are all unbarred; the rectrices 
are newly acquired, and show a very slight amount of barring, 
broken into spots; in other respects the plumage resembles 
that of K and L. 
O, from Percy Island. An adult bird, resembling L, ex¬ 
cept that it exhibits dark transverse bars on the inner webs 
of the rectrices, other than the central pair, and also on those 
of many of the primaries, secondaries, and tertials. 
P, from Port Essington, North Australia. An adult spe¬ 
cimen, which resembles L, with the following exceptions, 
viz.—a few very slight dark shaft-marks apparent on the 
centre of the crown of the head, and dark transverse bars on 
the tertials, and, less distinctly, on some of the secondaries. 
Q, from Rockingham Bay, N.E. Australia. An adult, 
with dark transverse bars on the tertials only; in other re¬ 
spects resembling P, with the exception of having well-marked 
dark shaft-marks on the nape, and also the striae on the 
crown of the head being rather more widely diffused. 
R, from the east coast of Australia. Adult, resembling O 
in all respects. 
The following are the principal dimensions of eight speci¬ 
mens of Haliastur intermedins and H, girrenera which are 
preserved in the Norwich Museum, and of which the sex has 
been recorded by the collector:—
