and  the  apical  part  much  curved  upwards  ; the  lamellte  slender,  rather  widely  set,  and  more  strongly 
constructed  anteriorly  on  the  inner  portion  of  the  lateral  margins  ; the  nostrils  large,  oval,  and  place<l 
near  the  base  and  culmen.  Wings  moderate,  pointed,  with  the  second  quill  the  longest,  and  armed  on 
the  shoulder  with  a tubercle.  Tail  moderate  and  nearly  even.  Tarsi  strong,  rather  shorter  than  th® 
middle  toe.  Toes  short  and  fully  webbed ; the  hind  toe  moderate  and  elevated,  and  slightly  lobed , 
l-he  claws  moderate  and  curved. 
The  type  of  this  division  is  generally  scattered  in  various  parts  of  the  old  world,  and  is  found  on  the  sea  coast,  a 
well  as  on  the  fresh-water  rivers  and  lakes  of  the  interior.  It  performs  periodical  migrations  to  the  more  north®’[ 
latitudes.  The  other  species  are  peculiar  to  Australia.  Marine  plants,  shell-fish,  and  molluscous  animals  form 
principal  food.  Their  nest  is  formed  of  grass,  lined  with  down,  in  the  deserted  burrows  of  rabbits,  which  are  o 
found  on  the  coast.  The  female  lays  from  twelve  to  fourteen  eggs.

The  European  species  of  tliis  division  occurs  also  in  most  parts  of  Asia  and  Africa,  and  is  said  to  be  prin^'P

the 
found  on  the  large  rivers,  and  but  rarely  on  the  sea  coast.  Their  food  consists  of  aquatic  vegetables,  as  we 
small  fry  of  fish  and  insects.  It  is  in  burrows,  especially  of  the  marmots,  on  the  banks  of  rivers,  that  the 
deposits  eight  to  ten  eggs.  Other  species  are  inhabitants  of  Australia  and  New  Zealand.

t It  was  in  1828  that  this  genus  was  established  by  M.  Boie  (Tsis),  yet  other  names  have  since  been  employed  coeq“’ 
Cosmonessa  of  M.  Kaup  (1829),  Dendronessa  of  Mr.  Swainson  (1831),  and  Lampronessa  of  Wagler  (1832).  These  are
