 This species is known  to scientific ornithologists by  two  specific names—cterulea and Audeberti ;  the former  
 of which, having the priority,  is  the one  adopted in the present work. 
 The Encephala cterulea may be stated to be one of  the very commonest of  the Trochilidæ, hundreds,  nay  
 thousands, being annually sent to Europe, and mounted under glass shades for ornamental purposes.  As may  
 be supposed,  these great numbers do not all  come from the  same  source :  some are sent from Brazil,  others  
 from Cayenne,  and others  from  the island of Trinidad.  I  must  here  remark that  there are two very well-  
 marked varieties of  this bird,  indicated  by the  greater or  lesser amount of  blue on  the throat ;  in all other  
 respects they  closely assimilate,  ll ie  countries favourable to the existence of the variety with the deep blue  
 colouring of the chin—the one  figured  on  the accompanying Plate—are,  French Guiana, Cayenne,  Para, and  
 the  islands  of Tobago and  Trinidad ;  while  the Antilles, Venezuela,  and  the  borders of  the Chamacures,  a  
 tributary of  the Amazon on  the  eastern dip of  the Andes,  are as favourable to the other.  The specimens  1  
 possess  from  the  latter  locality  were  procured  by  Mr.  Hauxwell,  while  my  Venezuelan  examples  were  
 collected by the late Mr. Dyson. 
 Mr. William Tucker informs me  that  in Trinidad  it is principally found  in  the large woods,  but  is  sometimes  
 met  with  in  the  more  open  parts of  the country and  on  the  pasture  lands ;  and  that  it  frequents  
 flowers of all kinds,  but appears to be especially partial to those of the Bois immortel. 
 Mr. Reeves  states,  that  though  this  species  is  common  at  Bahia  it  is very rare  in  the province of Rio  
 de Janeiro. 
 The nest and eggs of this bird have been  figured by M. Bourcier in the fifth volume of the  “ Annales des  
 Sciences Physiques,  &c.,  de Lyon,"  and  is  accompanied by the following  description s— 
 “ Ce nid représente un  demi-ovale obliquement coupé ;  il est formé  d’un mélange du duvet cotonneux que  
 contiennent  les  capsules  du  fromager  à  fruit  rond (Bombax gloiosum),  et  de celui que  fournit  le  Baobab  
 (Aiamoma digitati), vulgairement  appelle Pain de singe.  Sa  paroi  externe,  é laquelle  adhèrent  quelques  
 corps étrangers,  est recouverte d’un léger réseau de fils d’araignées. 
 “  Ce  nid était plaqué vers l’extrémité de la  page  inférieure d’une  feuille de Bambou, dont la plicature lui  
 offrait  un  abri contre  les rayons du  soleil  et contre  la pluie.  Dans  sa cavité  se trouvaient  deux oeufs  blancs 
 et de forme cylindrique.”  . 
 The Encephala  cterulea  is  a bird  of  great  beauty,  and differs from most others  in  the depth  of  the green  
 colouring of the chest and  under surface, which  it is quite impossible to represent m a drawing.  The female  
 differs  in  the lighter colouring of the green of the upper surface and in the almost white throat and abdomen,  
 the former,  however,  as well  as  the  flanks, being  beautifully  spotted  with  glittering  green;  the outer tail-  
 featliers also  of this sex are  tipped with greyish-white. 
 The male has the crown  and sides of the head,  the upper surface of the body, wing- and tail-coverts deep  
 grass green •  win»s  dark  purplish-brown ;  tail  dark  steel-blue, with  green  reflexions ;  chin  a deep shining  
 blue;  all  the under surface dark  glittering  green;  upper  mandible  dark  brown;  under  mandible  reddish 
 flesh-colour.  .  I   ,  . 
 The female has  the head and all  the upper surface  bronzy-green ;  wings  and  tail  as  in  the male,  except  
 that the outer feather of the latter is  tipped with grey;  under surface white, with a spot of glittering green  
 at  the  tips  of the feathers of the  throat  and flanks ;  under tail-coverts  green. 
 The  figures  in  the accompanying  Plate are  intended  to represent  the sexes of  the size of  life,  on a plant  
 the  botanical  name of which  is Eugenia Brttsiliensis.
