REVISION OF THE GENUS MALURUS. 
This is almost certainly the form described by Campbell ; 
although he gave no definite locality, his remarks suggest that 
his material came from near Port Augusta. Restricted in 
range and little known, nevertheless this race appears valid. 
The deep colour of the head, mantle and upper tail-coverts is 
constant in the adult males examined. 
Malurus (Malurus) splendens (Quoy and Gaimard). 
Climatically the south-west part of Western Australia 
inhabited by this species ranges from moist to arid. West of a 
line from Albany (the type locality of splendens ) to the coast 
north of Perth, the annual rainfall averages 30 to 40 inches 
and vegetation is luxuriant. Eastwards, the annual rainfall 
decreases to 10 inches or less. These extremes in climatic 
conditions are reflected in the material examined. Specimens 
from the dry habitat are much paler than those from the coastal 
area, and as they appear to be representative examples, they 
are here referred to a new subspecies.
