The Grouse arc ratlicr largo in size, lioavy in body, with small heads, tho nasal fossie filled with feathers concealing the nostrils
; moderately long necks, short wings, rounded and coneave beneath; stout legs and feet, the toes having pectinations of scales
along tho edges, the himl toe elevated above tlio piano of the rest; the tarsi covered with feathers, in tho Iloimsio only halfway,
in the Lagopida; to tlie claws. I commence my review of tlic family with 5Ir, Stephens' goims.
B O N A S A,
Mead cresicd, bill iJtorl, strong; wings short, concave beneath, third and fowrth primaries longest ; tail o f eighteen broad feathers;
lower h a lf o f tarsi naked, cot>c7.erf anteriorly with two rows o f scales; sides o f toes pectinated with scales; claws short and
Tins genus lias its rcproscntntivcs in both tho Old and Now Worlds, although the s|)ccics inhabiting the former iias not the
ruff so developed a.? have those belonging to America. Tliorc is but little dificrence in the plumage of the se.ves ; tlic female
being distinguisliod chiefly by the smaller size of the ruff; in the liuropeaii species, by the absence of tlm black throat. The
males arc polyganions, and desert the females during tho period of incubation. Those birds go in (locks, and on being distnrhcd
will frequently take refuge in trees. Tliey a rc :—

'J'liis last species differs from the rest in being uioiiogainouf, although the male does not remain witli the; fcimile while the
latter is setting, and also in not possessing tlie [icciiliar lialut of drumming, so cliaractoi'istic of the othci- species.

The forests of the Old World arc the home of ttio magnificent species composing this genus; but in .some localities wlierc
they «-ere formerly abundant, they now exist in greatly reduced nnmbcrs; indeed, in some places, have become extinct, Tho
