 above-given observations it is shown that this species has 

 two methods of changing its plumage.

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. Sliarpe, 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. 1 was specially pleased to find 

 between fifteen and twenty individuals of this species in the 

 hill-country of Western Anstralia, 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 \ATiting this still
