GREY-BREASTED SHRIKE ROBIN. 
Eopsaltria griseogularis griseogularis Gould. 
Swan River, Western Australia. 
Eopsaltria griseogularis wongani subsp. nov. 
Wongan Hills, West Australia. 
Separable from E. g. griseogularis in its duller coloration and smaller 
size ; the rump coloration greener and the yellow under-surface paler, with 
the grey encroaching farther on the breast and duller. 
Eopsaltria griseogularis quoyi subsp. nov. 
Albany, West Australia. 
This has the rump paler yellow than the typical form, but brighter than 
the eastern race or the northern one, while it is also darker above. This is 
the M. gularis Quoy and Gaimard, which was described from Kin g George 
Sound. 
Eopsaltria griseogularis rosince (Mathews). 
Eyre’s Peninsula, South Australia 
extending as far westward as Lake Dundas, West Australia. 
I have given the diagnosis above, and this form has the greenest rump 
of the series. It should be noted that the range of this species concludes 
at Eyre’s Peninsula and that E. australis does not occur in South Australia, 
so that the two species do not meet.
