The only Australian killed specimen I have examined is one in the British 
Museum, presented by Colonel W. V. Legge; it bears the following: “ 27.1.85. 
Derwent River, Hobart, Tasmania. Iris Hazelbrown. Bill black greenish 
slate above. Legs and feet black, webs black.” It belongs to the light form, 
and has the wings, tail, head and back dark brown, the head slightly lighter ; 
tips of feathers of lores, above the eyes, and towards back of neck white ; 
feathers of back of neck black-tipped, with dusky-grey bases, a broad white 
bar intervening ; the feathers of upper-back have few white tips ; upper 
tail-coverts white with alternate brown bars ; tail-feathers have white bases ; 
under-surface white, the feathers of the upper-breast more or less barred with 
brown tips, such coloration persisting on the sides of the body and becoming 
more pronounced on the flanks and under tail-coverts ; under wing-coverts 
and axillaries uniformly dark brown ; bases of primaries paler, dusky ; a 
faint yellowish-bufi tinge pervades the sides of the neck.
