TETRAONIDA, — ODONTOPHORINZ: PARTRIDGES OR QUAIL. 589 
forty-odd species are known. In habits, they agree more or less completely with the well 
known Bob-white. Our species are apparently monogamous, and go in small flocks, called 
‘« coveys,” usually consisting of the members of one family; they are terrestrial, but take to the 
trees on oceasion; nest on the ground, laying numerous white or speckled eggs; are chiefly 
granivorous, but also feed on buds, soft fruits, and insects ; and are non-migratory.

nearly equivalent to a determination of the species.
