Branta huchinsii, BANNISTER, Proce. Phila. Acad., 1870, 131. 
Branta canadensis, var. hutchinsti, Couns, Key, 1872, 284. 
Tail sixteen-feathered. Colors exactly as in the Vanada Goose, but size less. Length, 
about 24 feet; wing, 15-17; tail, 5-6; bill, 14-13; tarsus rather under 3. . 
Habitat, North America, but chiefly northern and western. 
Rare migrant, only recognized on Lake Hrie. Mr. Winslow informs 
me that several specimens have been taken at Sandusky Bay. 
Mr. Nelson, Bull. Hssex Ins., viii, 1876, 138, speaking of a series of eight 
Canada Geese examined by him says: 
“In tho lot were typical representatives of the two forms above named (B. canadensis 
and hutchinsti). In addition were several specimens which formed a direct chain in which 
it was impossible to tell where one variety ended and the other commenced. The size 
of the specimens, the coloration, and indeed every particular, aided in perfecting the 
series, except the number of tail feathers, which was eighteen throughout. In hutchinsi 
I have found this to be a very variable character, as a large portion of the specimens 
which agree perfectly with the dimensions of the latter possess the eighteen tail feathers, 
instead of sixteen, as given by authors.” 
Subjamily Anatinm. River Ducks. 
Neck and legs shorter than in geese. Tarsi scutellate in front, hind toe simple, feet 
small. Sexes dissimilar. The genera of this sub-family based upon form and relative 
proportion of bill to head and foot. 
GENUS ANAS Linneeus. 
Bill broad, rather larger than foot. Tail two-fifths the wing.
