 D u r i n g   the progress  of  the present  monograph  I   have repeatedly  had  the  pleasure of  offering my  thanks  
 to Thomas Reeves,  Esq.,  of Rio de Janeiro,  for the  liberal manner in which  he  placed  at my disposal  the  
 novelties  pertaining  to this  group of  birds which have  from  time to  time  come  into his  possession.  This  
 gentleman, who  has  resided in Rio  for many years,  has  lost no opportunity of  securing examples of  every  
 species  that  has  been  collected  in  that  part  of  South  America,  which  he  has  kindly  forwarded  to  
 me for the  furtherance of  the  present work.  Of  all  these birds, none have  been  of greater interest to  me  
 than the one figured on  the accompanying plate;  and this  interest has been  much  enhanced  by the circumstance  
 of the bird  having  been  killed  by  Mr.  Reeves  himself  during  a  visit  to Novo  Friburgo,  a district  
 skirting the virgin forests,  about  seventy miles from Rio.  When he killed it, Mr. Reeves  imagined  it to be  a  
 curious variety of the  Calliphlox amethystina ; but this is  not  the case, for it differs so much  from  that species  
 and all others,  that 1 am  even  at a loss  to know to what  geuus it  is most nearly  allied.  For the present  I  
 have placed it near the Chlorostilbontes,  as it more  nearly resembles  those birds in  its style of colouring than  
 any others ;  at  the  same  time its delicate  structure,  diminutive  wings,  and deeply forked tail  would  lead  to  
 the conclusion that it is  allied  to  the members of the genus  Calliphlox.  When additional  examples  have  been  
 procured  and the  female  has become known  to us,  then,  and  then only,  shall we be  able  to  determine  its  
 proper situation. 
 The whole of the body,  including the upper and under tail-coverts, iridescent  pale green and light  coppery  
 red, most brilliant on the throat;  the deeply forked tail steely dark  brown,  each  feather tipped with  a more  
 bronzy or purplish hue, which  is  seen  only in certain lights;  upper mandible  and  the tip  of  the  lower one  
 black,  the remainder of the latter apparently  reddish  flesh-colour. 
 Total length 3 i  inches ;  bill f  ;  wing  1-&-;  tail  HThe  
 figures  are of the size of life.  The plant  is  the  Gesneria purpurea.
