GULF FLYEATER. 
the basal portion being grey not black. I have also a series collected by Mr. 
Robin Kemp at the same place, and while these agree in detail, they all lack 
the basal black in the tail mentioned above. I have now concluded that this 
must be a slip and that these specimens represent Masters’s species. I have 
noted that probably Campbell’s “ typical” Icevigaster may be referable to this 
species, and I am tentatively regarding as a subspecies the form I described as 
Gerygone Icevigaster mungi. 
Differs from G. 1. Icevigaster in its much paler coloration above and below. 
This was written from comparison with birds from North-west Australia 
(coastal) which were regarded as typical levigaster, but which later acquisition 
showed to be separable subspecifically. 
At the same time Ps. mastersi Sharpe was regarded as a subspecies of 
Icevigaster, the type locality being regarded as Cape York. I corrected this 
later to Normanton, Gulf of Carpentaria, which is accurate. 
The very distinct white eyebrow, the pale brown upper coloration and the 
pure white under-surface separate this species. Its relations may be with 
Icevigaster, but to call this Buff -breasted Flyeater would be absurd. 
Two subspecies are tentatively attached : 
Ethelornis mastersi mastersi (Sharpe). 
Normanton, Queensland. 
Ethelornis mastersi mungi (Mathews). 
Mungi, Interior North-west Australia. 
The western form mungi is certainly very similar to levigaster, but the 
white bar towards the base of the tail-feathers (except middle ones) will 
distinguish it. 
If the bird described on p. 167 be not mastersi it can be called Ethelornis 
normantoni name nov.
