HALCYON PYRRHOPYGIA, Gould. 
Red-backed Halcyon. 
Halcyon pyrrhopygia, Gould in Proc, of Zool. Soc., September 8, 1840. 
Tis new Halcyon is an inhabitant of the interior, but over what extent of country it may range is not yet 
known. The only parts where I observed it was the myall-brushes (4cacia pendula) of the Lower Namoi, 
particularly those growing on the edge of the large plain skirting the Nundawar range of Major Sir Thomas 
Mitchell. It was usually seen sitting very upright on the dead branches of the myall- and gum-trees, 
sometimes on those growing out on the hot plains, at others on those close by the river-side. I succeeded 
in obtaining both old and young birds, which, judging from the size of the latter, I should suppose had left 
their breeding-place about a month before I arrived in the neighbourhood of the Namoi, in December. I 
also saw in this district the common or Sacred Halcyon, but in far less abundance than between the ranges 
and the coast. This latter species may be hereafter found to be more exclusively an inhabitant of the 
country bordering the sea, while the Red-backed Halcyon may be exclusively a denizen of the distant interior. 
The unusual colouring of the back at once distinguishes it from all the other members of the genus inha- 
biting Australia, but in its general economy and mode of living it presents no observable difference. 
Whether it remains during the whole of the year, or is a migratory bird like the common species, I was 
not able to learn; for although Mr. Charles Coxen had previously informed me of the existence of such a 
Halcyon ou the Namoi, he could give me no further account of it. 
Crown of the head dull green, intermingled with white, giving it a striated appearance: a broad black 
stripe commences at the base of the bill, passes through the eye, and encircles the back of the head ; upper
