BUFF-BREASTED FLYEATER. 
Ethelornis levigaster perconfusus, subsp. nov. 
Southern North-west Australia. 
A series from Point Torment and Derby are noticeably paler above than 
the preceding and average smaller ar.d the under-surface is almost pure white. 
The bill is notably smaller and in some specimens there is an indication of 
white towards the base of the tail-feathers, so that that very accurate orni- 
thologist, Mr. J. P. Rogers, mistook them at first for E. culicivorus. These 
specimens sometimes recall the species I regard as mastersi and these are the 
ones that have compelled me to suggest that probably more than one distinct 
species is being confused under the species name levigaster.
