ODONTOPHORINjE. 
It  is  in  North  and  Central  America,  as  well  as  in  Jamaica  and  other  "West  Indian  Islands,  that  the  species  of  this 
division  are  found.    Their  habits  and  modes  of  life  are  entirely  similar  to  those  given  in  the  first  genus.

Callipepla  Wagl.\ 
Bill  short  and  rather  weak,  with  the  culmen  slightly  elevated  at  its  base,  and  gradually  curved,  and 
the  sides  slightly  compressed  to  the  tip,  which  is  obtuse,  and  overhangs  that  of  the  lower  mandible ; 
the  lateral  margins  curved,  those  of  the  lower  mandible  slightly  bidentated  near  the  tip ;  the  nostrils 
basal,  placed  in  a  short  broad  groove,  with  the  opening  closed  by  a  membranous  scale.  Wings  moderate 
and  rounded,  with  the  quills  narrowed,  and  the  fourth,  fifth,  and  sixth  equal  and  longest.  Tail  long, 
broad,  and  more  or  less  rounded.  Tarsi  rather  shorter  than  the  middle  toe,  moderately  strong,  and 
covered  in  front  with  divided  transverse  scales.  Toes  long,  and  rather  slender,  with  the  inner  shorter 
than  the  outer  toe,  the  base  of  the  anterior  ones  united  by  a  short  membrane  ;  the  hind  toe  moderate, 
and  slightly  elevated  ;  the  claws  long,  rather  slender,  and  slightly  curved. 
These  elegant  birds  are  found  in  California  and  Mexico,  where  they  seem  to  prefer  the  dry  gravelly  or  sandy  plains 
or  similar  places  in  open  woods.  They  generally  live  in  bands  of  two  to  three  hundred  individuals,  and  seek  their  food 
on  the  ground,  which  consists  of  seeds,  catkins,  and  the  leaves  of  certain  plants,  as  well  as  various  kinds  of  insects. 
On  the  approach  of  winter,  they  leave  the  interior,  and  migrate  in  large  flocks  to  the  immediate  vicinity  of  the  coast. 
They  are  extremely  quarrelsome  and  fight  with  great  determination.  The  nest  is  formed  on  the  ground  in  the  midst  of 
a  close  thicket,  and  is  made  of  grass  and  dry  leaves.    The  female  usually  lays  from  eleven  to  fifteen  eggs.

*  Established  by  Wagler  in  1832  (Isis,  p.  277.).     It  is  coequal  with  Lophortyx  of  the  Prince  of  Canino  (1838).
