DONACOLA FLAVIPRYMNA, Gould. Yellow-rumped Finch. Donacola flaviprymna, Gould in Proc. of Zool. Soc., part xii. p. 80. A stvaLx specimen, and the only one I have ever seen of this pretty Finch, was presented to me by Benjamin Bynoe, Esq., Surgeon, R.N., who procured it on the banks of the Victoria River during the late surveying voyage of H.M.S. Beagle. It is very nearly allied to the Donacola castaneothorax, but is specifically distinct from that as well as from every other known species of this now numerous tribe of birds. I regret to add that nothing whatever is known of its habits or mode of life; but in these respects it doubtless as closely assimilates to its congeners as it does in form. Head pale fawn-colour ; back and wings light chestnut-brown ; under surface buff; upper tail-coverts wax-yellow ; under tail-coverts black ; tail brown. The figures are of the natural size. ‘we © A ©) W. CA
