 So far as my knowledge extends,  two  specimens only of this bird have  as yet reached Europe;  one of these  
 is in the collection formed by the late George Loddiges,  the  other in my own.  It is  a bird of great  interest  
 to me,  since it happens  to  be  a  species which will  not clash with any other: I mean, has  no near ally with  
 which  it  can  be confounded.  It is  true that  the Circe latirostris has a similarly marked tail, and also a blue  
 breast,  but  it  is  destitute  of  the  glittering  bluish-green  crown;  and  it  is  moreover  fully  a  third  larger  
 than  the present bird. 
 When  M.  Bourcier  described  the  Circe Douhledayi,  no  satisfactory information was  on  record as  to the  
 country of which  it is a native, and  the Rio Negro  was given  as the  one  in which  it was presumed  it might  
 be found;  but that part of South America is not, I believe,  the  locality in which it may be looked fo r;  like  
 the  Circe  latirostris,  it  will,  I  think,  prove  to  be  a  native  of  the  more  northern  country  of  Mexico.  
 I have  two  reasons  for  believing  this:  in  the  first  place,  all  the  Humming-Birds with obscure  tippings to  
 their tails,  such as latirostris,  Caniveti,  auriceps, &c.,  are  denizens  of  that  country;  and  in the second,  the  
 specimen  in  my collection,  which  was  kindly given  to. me  by my warm-hearted friend  Saucerotte,  has  the  
 words  “ Chimantla, Mexico,” written on  the label  attached to it. 
 It will  be  seen,  by the above list of synonyms, that I  have found it necessary to  include therein the specific  
 name  of Lereboulleti, proposed  for  this  species  by Dr. Saucerotte;  that name is  attached to the specimen  
 above  mentioned,—a  circumstance which  enables me  satisfactorily to determine that Lereboulleti of Saucerotte  
 and Douhledayi of Bourcier are identical;  the latter name,  having  the  priority,  is  necessarily the one  
 adopted. 
 In naming this  bird after one who has since departed, M. Bourcier was desirous of paying  a just compliment  
 to an able entomologist and most amiable man :  the name of Doubleday is  too well known  among the  
 workers in natural history  to need any comments upon his many merits at my hands. 
 Crown of the head  shining metallic bluish green;  throat brilliant  blue,  passing into green on the breast;  
 all  the  upper  surface, wing-coverts,  upper  tail-coverts,  and  abdomen  dark  bronzy green;  wings  purplish  
 brown;  tail black,  glossed with  steel-blue  and  tipped with  brownish  grey, which  lessens  in  extent  as  the  
 feathers  recede  from  the  centre;  under  tail-coverts  brown,  edged with  grey;  bill  apparently red  at  the  
 base, with» a darker tip. 
 The  Plate  represents  a  bird, which  appears  to  be an  adult  male, of  the  size  of  life.  The plant is  the  
 Calliandra Harrisii.
