THE VIRGINIA PARTRIDGE. 393 
Famy PERDICIDZ. Tue PARTRIDGES. 
Nostrils protected by a naked scale; the tarsi bare and scutellate. 
The Perdicide differ from the Grouse in the bare legs and naked nasal fossz; 
they are much smaller in size and more abundant in species; they are widely dis- 
tributed over the surface of the globe, a large number belonging to America, where 
the sub-families have no Old-World representatives whatever; the head seldom, if 
ever, shows the naked space around and above the eye, so common in the Tetraonide ; 
and the sides of the toes scarcely exhibit the peculiar pectination formed by a suc- 
cession of small scales or plates. 
Sub-Family ORTYGINE. 
Bill stout; the lower mandible more or less bidentate on each side near the end. 
The Ortygine of Bonaparte, or Odontophorine of other authors, are characterized 
as a group by the bidentation on either side of the edge of lower mandible, usually 
concealed in the closed mouth, and sometimes scarcely appreciable; the bill is short, 
and rather high at base, stouter and shorter than what is usually seen in Old- 
World partridges; the culmen is curved from the base; the tip of the bill broad, 
and overlapping the end of the lower mandible; the nasal groove is short; the tail is 
rather broad and long. ‘ 
ORTYX, STEPHENS. 
Ortyx, SrEPHENS, Shaw’s Gen. Zool., XI. (1819). (Type Tetrao Virginianus, L.) 
Bill stout; head entirely without any crest; tail short, scarcely more than half 
the wing, composed of moderately soft feathers; wings normal; legs developed, the 
toes reaching considerably beyond the tip of the tail; the lateral toes short, equal, 
their claws falling decidedly short of the base of the middle claw.
