Subspecific Characters . — Similar to diemenensis in colouration, but differ- 
ing from all forms in the great length of bill. 
The three specimens from which A. J. Campbell described 
this race are the only available representatives of pasitta from 
King Island. The single adult (type) is in very worn plumage 
which accounts for the greater length of wing and tail of the 
immature female. The outstanding feature of this race is the 
extraordinary long bill which is accepted as characteristic only 
in view of the fact that both immature specimens exhibit the 
same feature. 
During a recent visit to King Island no specimen of this 
form was seen, although I made an intensive search. On the 
other hand Acanthiza ewingi was fairly numerous.
