A. d ad. sk., Reedy Hole. 
B. ? ad. sk.. Red Mulga Creek. 
Two specimens similar to those from eastern and southern Australia. The 
male is more strongly washed with rufous upon the head and breast than the 
female, but considerable variation exists in the tints of plumage in this species. 
Apparently this rufous wash increases with age, for I have never observed it in 
young birds. 
[Whilst cutting down a dead tree at Red Mulga Creek for fuel, a female bird 
flew out of a hollow branch, which proved to be her nest and dwelling-place at the 
same time. Several others were subseciuently seen, and one was shot at mid-day near 
the George Gill Range. As they are nocturnal in their habits, this bird was no 
doubt disturbed from its retreat by the noise made by our party in passing. 
Their food consists chiefly of nocturnal lepidoptera.]

Two adult males, Crown Point; one adult female, llermannburg. 
[These birds were found throughout Central Australia, but were most 
plentiful near the Finke River, whei’e they might bo seen soaring near the water 
in pursuit of the winged insects on which they feed. At Hermannburg I had the
