Jii/l  moderate,  depressed,  and  broad,  with  the  culmen  flattened,  and  curved  at  the  tip,  which  overlaps 
thai  of  <lir  under  inaudible  ;  the  nostrils  large,  oval,  and  placed  in  the  middle  of  the  bill  in  a  large 
membranous  groove  ;  the  membrane  extends  over  the  base  of  the  culmen.  Wings  short,  imperfect, 
and  furnished  with  long  soft  feathers.  Tail  not  apparent.  Tarsi  very  long,  strong,  and  covered  in 
front  with  broad  transverse  scales.  Toes  short,  the  lateral  ones  shorter  than  the  middle  one,  and 
unequal,  the  inner  the  shortest ;  the  claws  moderate,  strong,  and  compressed. 
The  birds  of  this  genus  are  found  on  the  plains  of  South  America.  They  are,  says  Mr.  Darwin,  shy,  wary,  and 
>(>lit:iry,  and,  although  so  fleet  in  their  pace,  they  fall  a  prey  without  much  difficulty.  They  generally  prefer  running 
against  the  wind,  yet  on  the  first  start  they  expand  their  wings  to  assist  them  in  their  progress.  During  the  heat  of 
the  day  they  sometimes  enter  a  bed  of  tall  rushes,  where  they  squat  concealed  till  quite  closely  approached.  These 
birds  will  cross  rivers,  or  pass  from  island  to  island,  by  swimming,  which  is  performed  rather  slowdy,  very  little  of  their 
bodies  appearing  above  the  water,  and  their  necks  extended  a  little  forwards.  They  feed  on  vegetable  matter,  such  as 
root-  and  grass ;  but  Mr.  Darwin  has  repeatedly  seen  three  or  four  come  down  at  low  water  to  the  extensive  mud  banks, 
which  are  then  dry,  for  the  sake  of  catching  small  fish.  The  nest  is  a  shallow  excavation,  wherein  are  placed  as  many 
as  twenty-two  to  seventy,  or  even  eighty,  eggs ;  these  are  deposited  by  several  females:  many  eggs  are,  however, 
scattered  singly  over  the  plains,  and  thereby  become  useless.  The  male  bird  alone  collects  them,  and  hatches  the  eggs, 
and  for  some  time  afterwards  accompanies  the  young ;  at  which  time  the  males  are  occasionally  fierce,  and  even 
dangerous.

Bill  moderate  and  broad,  with  the  culmen  at  the  base  elevated,  and  sloping  to  the  tip,  which  overlaps 
that  of  the  under  mandible  ;  the  nostrils  placed  in  a  large  membranous  groove,  with  the  opening

covered  in  front  with  reticulated  scales,  except  near  the  toes,  where  there  are  a  few  transverse  ones,  and 
posteriorly  with  a  series  of  rough  scales.  Toes  moderate,  the  lateral  ones  unequal,  the  inner  one  the
