By the term “post-acetabular area” is understood that portion of the
dorsal aspect of the pelvis which is bounded in front by a line drawn
through the acetabula.
The _Cracinæ_, or Curassows, are found in Mexico, in Central and in
South America; the _Oreophasinæ_ are represented by a single species,
_Oreophasis derbianus_, a bird nearly as large as a Turkey, occurring in
the wooded region of the Volcan de Fuego, Guatemala, at an altitude of
10,000 feet. Of the _Penelopinæ_ one species only is found in the United
States.
