THE BIRDS OF AUSTRALIA. 
Territory, wrote: “ A perfect pair, and similar to hecla, and probably also 
to tribulationis, both Mathews subspecies for North-west Australia. Wings 
alike (55 m.).” Examining one female from Groote Eylandt he has added: 
“ Same as N.T. birds. My former note may be considered somewhat ambigu¬ 
ous. The thought I intended to convey was that hecla, from Kimberley 
District, and probably tribulationis, because from the same district as hecla, 
were both synonymous with Gould’s lutea.” He does not mention any dis¬ 
tinction in the sexes.
