ESTRELDA ANNULOSA, Gould.
Black-rumped Finch.
Amadina atmulosa, Gould in Proc. of Zool. Soc., Part VII. p. 143.
T h i s species was one o f several, collected by the Officers of H.M.S. the Beagle, and for the specimens from
which my figures were taken I am indebted to Messrs. Bynoe and Dring. The bird has also been more
recently brought to England by Captain Grey : a ll the specimens here alluded to were collected on the
north-west coast, and I find it is not unfrequently seen on the Coburg Peninsula, where it inhabits the
grassy hanks o f running streams, in small families o f from six to ten in number.
I t differs from Bicheno’s Finch in the spots and markings on the upper surface being rather less defined,
and in the colouring of the rump, which in this species is black, while in the other it is white.
Face, ear-coverts and throat white, surrounded by a jet-black band, which is broadest on the forehead ;
chest greyish white, bounded below by a conspicuous band of b lack ; lower p a rt o f the abdomen w h ite ;
crown o f the head, back o f the neck, and back greyish brown marked with numerous fine transverse lines of
o-reyish wh ite; rump, upper and under tail-coverts and tail b lack ; wings blackish brown, the secondaries
and coverts thickly dotted w ith fine markings o f greyish wh ite; bill and feet lead-colour.
The figures are those o f a male and a female of the natural size.
