Enl. 379, 982, 983 (The Egyptian Goose), remarkable for 
the lustre of its colours and the small spur attached to its wing, 
also belongs to this subgenus; it is sometimes domesticated, 
but always retains a propensity to return to its wild state. It 
is the Chenaloper or Fox Goose, held in veneration among the 
ancient Egyptians on account of its attachment to its young. (2)

smaller bill, the membrane of which is much broader, and extends 
a little upon the forehead. 
Cer. cinereus, Lath., Col. 206; Vieill. Gal. 284, is the only one

Anas, Meyer. 
Ducks, properly so called, have the bill broader at base than it 
is high, and wider at the end than towards the head; the nostrils 
nearer to its back and base. ‘Their legs being shorter than those of — 
Geese, and placed farther back, renders walking more difficult to 
them than to the latter. Their neck also is shorter; the trachea is 
inflated at its bifurcation into cartilaginous capsules, the left of 
which is usually the largest.
