DONACOLA  FLAYIPRYMNA,   Gould. 
 Yellow-rumped  Finch. 
 Donacola flamprymna, Gould in Proc.  of Zool. Soc., part xiii. p.  80. 
 A s in g l e  specimen, and the only one  I  have  ever  seen o f this  pretty F inch, was presented  to me by Benjamin  
 Bynoe,  Esq.,  Surgeon, R.N., who  procured  it  on  the  banks  o f  the Victoria River during  the late surveying  
 voyage  o f H.M.S. Beagle.  I t is  very nearly allied  to the Donacola castaneothorax,  but is  specifically distinct  
 from  th at  as  well  as from  every other known  species  o f  this  now  numerous  tribe  o f  birds.  I  reg ret  to  
 add  th at  nothing whatever  is  known  o f  its  habits  or mode  of lif e ;  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.
