THE BIRDS OF AUSTRALIA. 
I then added 
Philemon argenticeps melvillensis. 
“ Differs from P. a. alexis in its very much smaller size generally and darker 
upper-surface. MelviUe Island.” 
and 
Philemon argenticeps kempi. 
“ Differs from P. a. argenticeps in its generally smaller size. Cape York, 
Queensland.” 
and 
Philemon argenticeps broomei. 
“ Differs from P. a. argenticeps (from Port Essington) in its larger size and 
longer bill, Napier Broome Bay, N.W.A.”, and in my 1913 “ List ” I queried 
the Melville Island form as distinct from the mainland one and allowed four 
sub-species alone. 
At the present time, according to Campbell’s King River birds, the 
Melville Island form is quite distinct, and I admit all five named forms under 
the genus name Neophilemon thus : 
Neophilemon argenticeps argenticeps (Gould). 
Neophilemon argenticeps alexis (Mathews). 
Neophilemon argenticeps melvillensis (Mathews). 
Neophilemon argenticeps kempi (Mathews). 
Neophilemon argenticeps broomei (Mathews).
