Nests and Eggs. Very similar to those of Gilbertornis rufogularis. 
Breeding-season. August to November. 
Gould described a species of Pachycejphala as P. inornata, and then a few 
years afterwards introduced another new species as P. gilbertii. When he 
recognised that these referred to the same species, he wrongly continued the 
usage of the later name and remarked that the former had been given to the 
young, recording: “The specimens transmitted to me by Gilbert are, I believe, 
all that have yet been procured. Although the P. gilberti is nearly allied to 
the P. rufogularis, it may readily be distinguished by the rufous colouring being 
confined to the throat, and not ascending upon the fore-head and occupying the 
space between the bill and the eyes as in that species ; it is also a smaller bird 
in all its admeasurements. It is an inhabitant of the interior of Western 
Australia. The following notes, which are all that is known of its history, 
accompanied the specimens sent to me : ‘ This species inhabits the thick brushes 
of the interior. It is an early breeder, as is proved by my finding a nest with 
three newly hatched young birds in the middle of August. The nest was built 
in the upright fork of a small shrub about four feet from the ground. It was 
deep, cup-shaped in form, and constructed of dried grasses, and except that 
it was rather more compactly built, it was very similar to those of the other 
members of the genus.’ ” 
Mr. F. E. Howe has written me : “ Whilst strolling among some small 
Murray Pines that were growing in a depression of the sandhills at Pine Plains 
during September 1907, in company with Messrs. Ross, Mattingley and
