Bill  short  and  broad,  mth  the  ciilmen  elevated  at  the  base  and  much  arched,  and  the  sides  gradually 
compressed  to  the  tip,  which  is  obtuse ; the  lateral  margins  curved,  those  of  the  lower  mandible  slightly 
bidentated  on  each  side,  and  the  gonys  moderate  and  ascending  ; the  nostrils  basal,  and  placed  in  a short 
broad  groove,  with  the  opening  covered  by  a membranous  scale.  Wings  short  and  round,  with  the 
tertiaries  longer  than  the  primaries  and  pendent.  Tail  very  short,  and  hidden  by  the  coverts.  Tarsi 
strong,  shorter  than  the  middle  toe,  and  covered  in  front  with  divided  transverse  scales.  Toes 
moderate,  strong,  and  strongly  scutellated;  the  inner  shorter  than  the  outer  toe ; the  lateral  toes  slightly 
united  at  their  base ; the  hind  toe  elevated  and  strong ; the  claws  long,  very  strong,  slightly  curved, 
and  obtuse. 
The  species  of  this  division  are  peculiar  to  Mexico;  and  their  habits  and  manners  are  unknown.
