in Marcli 1919. None were noticed in the vicinity of Cape 

 Mentelle, where they were not uncommon wlien I was there 

 in 1903, and the coastal scrubs \^ ere intact, 'lliis is a very 

 seclusive, quiet species, feeding on tlie ground beneath thick 

 scrub, especially near any small brook. 



Pachycephala pectoralis occidentalis. 



Western Thickheads were common about Broome Hill, 

 and all south-western districts. 



Lewinornis rufiventris didimus. 



T did not see a single specimen of the Southern liufous- 

 broasted Thickhead on my 1919 trip, although they are 

 usually common about Broome Hill. 



Gilbertovnis inornata gilbertii. 



No Blaek-lored Thickheads were seen in February or 

 March 1919 about Broome Hill, although they are usually 

 fairly numerous there, their loud notes speedily attracting 

 attention.

 I picked the bird up, my first impression was that I had

 striking I'esemblance in the {dumage of female and immature

On 30 September, 1913, I saw a similar bird, also below 

 some mangroves, busily eating small crabs and other Crus- 

 tacea on the edge of the receding tide. This specimen was 

 a female with enlarged ovaries. My next visit to tliese 

 mangroves was early in June 1916, and on the Gth of that
