THE BIRDS OF AUSTRALIA. 
mating, but no nests were seen although I watched closely. This is a water- 
loving species and was never seen far from water on the north side of the 
island.” 
McLennan’s notes from his King River trip read : “ King River, 2/11/15. 
Single bird seen at spring near camp. 9/11/15. Shot three birds and saw 
more at spring near camp. Often seen after this date about the salt pans and 
along edge of mangroves. Roper River. Fairly numerous in places along 
river and in the mangroves over the river, near Egret rookery. Stomach, 
insect and termites’ remains.” 
Of the specimens procured Campbell observed: “ Have darker flanks 
than their near ally, rufogularis, and have a white throat and brown (buffy) 
breast mark.” 
In my “ Reference List ” no subspecies were included, the only locality 
being Northern Territory, the species being lumped in Certhionyx. 
Receipt of specimens from North Queensland enabled me to describe 
Certhionyx albogularis yorki. 
“ Differs from C. a. albogularis in being much paler above ; the band on the 
breast lighter ; it is also smaller ; wing 64 mm. Cape York, North Queens¬ 
land.” 
This appeared in my 1913 “ List,” where they were referred to the 
correct genus Conopophila, and I allowed: 
Conopophila albogularis albogularis (Gould). 
Northern Territory. 
Conopophila albogularis yorki Mathews. 
North Queensland. 
Although Ogilvie-Grant indicated the sensible differences in the form 
inhabiting South-west New Guinea as paler brown above with the rufous 
band across the chest not so rich, he did not name it, so I propose: 
Conopophila albogularis mimikce subsp. nov. 
Type from the mouth of the Mimika River, 
South-west New Guinea. 
It has also a much paler grey head.
