There is little of interest in the skin obtained at Katanning, 
except that the under surface, save for the tail-coverts and 
throat, is brown; the coverts are white, while the throat is 
a dull white. This probably indicates a stage between the 
nestling and adult. Wing 3'45 inches.

The first notice of this species, as such, is to be found in 
' The. Ibis ' (1899, p. 303), but it is very brief and refers only 
to the male. Up to the moment of writing no description 
has appeared, in this colony, of the female. As, however, 
Mr. Campbell has sent an account of both sexes to 
Dr. Sharpe, no doubt it will soon follow, and I am able to 
devote my attention to the several stages marked above which 
deal with immature examples. I was specially pleased to find 
between fifteen and twenty individuals of this species in the 
hill-country of Western Australia, and each time to note the 
large black cap and small white forehead, that convinced me 
of its being distinct from the eastern P. leggii. Like our 
Robin it does not confine itself to forest-land only, but is to 
be found in lightly timbered country. Eggs were collected 
last season in the Stirling Range, one of which was given to 
me during my visit, and at the moment of waiting this still
