 AMAZILIA  YUCATANENSIS. 
 Yucatan  Amazili.

 ¡ ■ 8  m m   to  Dr.  Cabot,  of  Boston, North America,  for  the  loan  of  the  type  specimen  of  his  
 lYocMw,  Yucaianensis,  a bird  which  differs  from  every other  species  that  has  come  nnder  my notice.  It  
 is  perhaps  most  nearly allied  to  the Amazilia  cenimeentris,  but  differs  in  the  truncate form  of the  green  
 colouring of  the  throat, which  in  that  bird extends  down  each  flank.  Dr.  Cabot  sent  at  the  same  time  
 another specimen, which he considered to be  the  female;  and  this may possibly be  the  case; but  I suspect  
 that  it  will  prove  to  be  another  species,  the  A.  cinnamomea  (A.  coralHrostris  of  my  work).  The  
 upper  figure  in  the  accompanying  plate  is  an  exact  representation  of  this  specimen;  and  it  remains  
 for future research to determine whether my surmise be correct or not.  In all probability the A. cinnamomea  
 flies in Yucatan,  as  it is  very common in  the neighbouring countries of Honduras  and Guatemala. 
 The following is Dr. Cabot’s description  and brief account of  this species,  published  in the • Proceedings  
 of the Boston Society of Natural History,’ to which,  I  learn,  he  has  nothing to add;  for,  in  a  letter  dated  
 April 30,  1859,  he says,  “ It gives  me great pleasure  to aid you  as  far as I am  able in your most  interesting  
 and  beautiful work;  but  I regret exceedingly to say  that it is  a long time since my observations were made,  
 and that my notes were  unfortunately lost overboard while  coasting along  the  shore  of Yucatan  in a canoe,  
 I  regret also  that I have no duplicate of the male to present  to you,” 
 “  Trochilus  Yucaianensis.  Length 4 inches.  Bill f  of an  inch.  First primary longest; primaries curved,  
 broadest  at  their  tips ;  tail,  somewhat  forked,  rather more than  I7  inch  long,  consists of ten  feathers;  
 bill  light yellowish  at base and along centre  of mandibles,  dark horn-colour at  tip and  halfway  along sides;  
 male  brilliant  shining  emerald  on chin,  throat, and  upper part  of  breast;  head,  upper  part  of  neck,  and  
 back  dull  golden  green  with  some  metallic  reflexions;  lower  part  of  breast,  belly,  under  tail-coverts,  
 central and upper part of tail-feathers light bay;  tips and both  sides of central  tail-feathers  and outer side  
 of  lateral  tail-feathers  dark golden green with metallic reflexions ;  vent white;  female  nearly  the  same  as  
 male,  but rufous  instead of bright emerald on  chin,  neck,  &c.,  and less white about vent. 
 “ This is  the most common Humming-Bird found  in Yucatan.  It was seen  in  numbers about  the acacias  
 which grew  upon  the  tops  of  the ruined  buildings, where the  specimens  from  which  the  above  description  
 was  taken were procured.” 
 The  figures  are of the  natural  size.  The  plant  is  the  Passiflora Meduscea.
