Malurus ( Rosina ) coronatus Gould. 
A distinctive species, but one of the least known of the 
genus. Its range appears to be a narrow inland belt of country

to the Leichardt River. Though invariably accepted as much 
the largest of the genus, it is equalled in all but length of culmen 
by M. elegans.
