[The Chestnut-rumped Thorn-Bill was very plentiful in 
the interior. It is the only species that extends so far north 
as the Gascoyne River, where, how r ever, it is rare. Unlike 
the other western forms, A. uropygialis is confined to the dry 
central districts, and does not extend to the coast in the 
south-west. It also differs from the other species in its 
nesting-habits—Building in the crevices or hollows of low 
tree-stumps.— G. C. >8.]
