 Or  the  five  or  six  known  species  of  the  genns  Ct/tmtmyia  the C. Francite  may be  regarded as the  most  
 beautiful,  inasmuch  as  it is characterized  by a far  greater  amount of  glittering colour than  any of  its  congeners, 
   and  by  these glittering hues  predominating on the sides and nape of the neck  parts not generally  
 adorned with any fine colouring;  there are, however,  exceptions to all rules in  the  colouring of Humming-  
 Birds,  and this is a case in point.  The glittering of the parts referred to is  so resplendent,  that it is  out  of  
 the power of any person, I believe, to portray them; hence art and device are in this instance  at a nonplus.  
 In  the accompanying Plate a representation of these feathers is  attempted with the ordinary media.  If  the  
 reader can  imagine the neck-plumes to be lit np with  the most brilliant and glittering light possible, he may  
 have some faint idea of their  loveliness;  it  is  only,  however,  in  certain lights  that  these  splendid  colours  
 appear;  particular  states of  the atmosphere,  or a certain condition of light,  are requisite to see them in all  
 their  brilliancy.  Viewed from  behind, an  obscure  tint  is  alone visible;  reverse  the  position,  so  that  the  
 rays of light fall upon the bird at a certain angle,  and yon become at once astonished at the difference. 
 I believe  the female  of  this species has  no brilliant  colouring  on  the  crown,—a t  least we  have  not  yet  
 received any  example  thus  adorned;  if,  then,  this  conjecture  be correct,  the  upper figure  in  the  opposite 
 Plate represents  this sex.  _  . 
 M. Bourcier tells us  that he has named this  species  in  honour of a Mademoiselle Francia Bourcier, who 
 is, I believe, his amiable daughter. 
 Crown  of  the  head shining  metallic  blue;  sides and  nape of  the  neck  glittering  metallic  light  green ;  
 upper surface, and wing-coverts bronzy green, changing  into coppery red  on the  lower  part of the back and  
 upper tail-coverts; wings purplish brown;  tail bronze;  throat,  centre of the abdomen, and under tail-coverts  
 snow-white;  flanks bronzy green;  upper mandible  and tip of the lower one black;  remainder of  the under 
 mandible fleshy ;  feet dark brown. 
 The female or yonng male has the crown green ; only a trace of the coppery hue on the upper tail-coverts,  
 and the lateral  tail-feathers crossed by an obscure dark band. 
 The  Plate  represents  two  males  and  the female,  or  young male, of  the  natural  size.  The  plant  is  the 
 Cuphea cordata.
