Crossoptilon  Hodgs.'\ 
Bill  moderate,  broader  at  the  base  than  high,  the  sides  slightly  compressed  and  sloping,  with  the 
lateral  margins  curved,  and  spreading  over  the  lower  mandible,  and  the  culmen  arched  to  the  tip,  which 
is  lengthened,  and  hangs  much  over  that  of  the  lower  mandible ; the  nostrils  basal,  lateral,  with  the 
opening  large,  suboval,  and  partly  hidden.  Wings  moderate  and  rounded,  with  the  fourth,  fifth,  and 
sixth  quills  nearly  equal  and  longest.  Tail  lengthened,  composed  of  very  broad  feathers,  and  much 
rounded  at  the  end,  the  coverts  lengthened  and  covering  its  base.  Tarsi  strong,  rather  longer  than 
the  middle  toe,  covered  in  front  with  transverse  divided  scales,  and  armed  with  a spur.  Toes  moderate, 
the  anterior  ones  united  at  their  base  by  a membrane,  the  lateral  toes  nearly  equal,  and  the  hind  toe 
short  and  elevated  ; the  claws  long,  curved,  and  strong.  The  sides  of  the  head  covered  only  with  a 
papillose  skin,  and  the  whole  of  the  feathers  decomposed. 
This  remarkable  bird  is  peculiar  to  the  mountains  of  Thibet,  and,  from  its  extreme  rarity,  its  habits  and  manners 
have  not  yet  been  recorded.

* M.  Temminck  established  this  genus,  in  his  Hist.  Nat.  Pig.  et  Gall.,  in  1815.  In  1816  Vieillot  used  Biplectron  for  this  division, 
t It  was  in  1838  that  Mr.  Hodgson  established  this  genus  {Journ.  As.  Soc.  Beng.  vii.  p.  864.).
