THE BIRDS OF AUSTRALIA. 
of his own types. This collection was the first to arrive in England, 
and I cannot express too fully my appreciation of his action. 
I have to ask all my friends who have supplied field-notes to 
continue to do so, and from all my readers who have not yet 
contributed I would beg assistance. I have in every case acknowledged 
the source of every note throughout my work. 
To my publishers, Messrs. Witherby & Co., I am much obliged for 
the care they have always shown in turning out the work in the very 
attractive way it appears. 
I would ask all who are interested in the Ornithology of Australia 
to differentiate between “ species ” and “ subspecies ” ; then, freed from the 
shackles of sentiment and binomials, we will have a new ornithology for 
Australia as scientific as that of any other country. 
To those who admit that there are “ subspecies,” trinomial nomen- 
clature is the only usage. To those who do not, let them only name 
“ species ” and leave the naming of “ subspecies ” to others. To name “ sub- 
species ” binomially is of course unscientific. 
In spite of the fierce opposition to trinomials, the younger generation 
of workers in Australia already shows signs of being up to date. 
On page 274, line 13, it was stated in error that the bird was “figured,” 
but no Plate has been prepared of Aptenodytes patagonica halli.
