(1877); North, Nests and Eggs Austr. Bds., p. 82 (1889). 
One male and female, Eeedy Hole; two females, LeYi Bange. The female of 
this species has a distinct rufous eye-hrow; the external wehs of the innermost 
primaries, secondaries, and wing-coYerts washed with pale rufous, and all the 
under surface strongly tinged with huff. Bill, hrown ; hase of the lower mandible, 
horn colour. 
[These birds are Yery similar in habit and choice of country to C. harmotiica. 
They were first found at Eeedy Hole, where they were hopping along the branches 
of the eucalypts, examining the creYices for spiders, etc., or on the ground. Their 
beautiful note as they called to each other proved very entertaining. Mr. Cowle 
has kindly forwarded me two of their eggs, taken from a nest near his camp. 
They closely resemble those of C. harmonica in size, color, and markings.]

on the lower throat and breast, and which is not so dark or well-defined as in the 
adult male.
