THE BIRDS OF AUSTRALIA. 
connection with my examination of the types. It will be noted that the 
date given for the type is the furthest north Hill said that he saw it, while 
the date given for the co-type is twelve days earlier than Hill said he met 
with it. 
My notes, written from examination of the type when in Australia, 
read: “The type of D. striata rufa (Campbell and Kershaw) Lat. 19° 27" about 
160 miles north of Survey Camp IV., July 3rd, 1911, differs from D. s. howei 
in having the upper-surface with the feathers very rufous, and the white 
shaft-streaks not bordered with black, except some of the feathers of the 
forehead. It is more like ‘ oweni ’ (Mathews).” 
The co-type (spirit specimen) collected at Lander Creek, Northern Territory, 
June 2nd, 1911, has the white shaft-streaks narrowly fringed with black. 
My description of Amytornis whitei reads : “ Differs from A. striatus 
in being larger in all its admeasurements, the bill being especially large. 
It is also redder on the back and underparts,” while I wrote of Amytornis 
striatus oweni that it “ Differs from A. s. striatus (Gould) in having the upper- 
surface bright chestnut instead of rusty-brown, and the white shaft-streaks 
almost devoid of black edgings, which form such a marked character in 
A. s. striatus .” 
The following three subspecies are recognisable : 
Diaphorillas whitei whitei Mathews. 
Coongan River, Mid-w r est Australia. 
Diaphorillas whitei oweni Mathews. 
East Murchison, West Australia. 
Diaphorillas whitei rufa Campbell. 
Interior of Northern Territory.
