1'. Feet incompletely or not at all webbed. 
If the bird you want to name lias fully webbed feet, read down 
the key from 1; if not, go to 1', and read down. The numbers fol¬ 
low consecutively from each heading. In this case the birds with 
fully webbed feet are divided again into several classes, and those 
without fully webbed feet also have subdivisions. 
1. Feet fully webbed (except Grebes in Pygopodes, which have the toes 
lobed or margined). 
2. Foot with three webs, all four toes connected. 
Steganopodes : Totipalmate Swimmers, p. 3. 
2'. Foot with two webs, three front toes connected. 
3. Nostrils tubular . Tubinares : Tube-nosed Swimmers, p. 3. 
3'. Nostrils not tubular. 
4. Edges of mandibles toothed or serrate. 
Anseres : Lamellirostral Swimmers, p. 3. 
4'. Edges of mandibles not toothed or serrate. 
5. Legs placed far back, wings short. 
Pygopodes: Diving Birds, p. 2. 
5'. Legs placed near middle of body ; wings long and pointed. 
Longipennes : Long-winged Swimmers, p. 2. 
1'. Feet incompletely or not at all webbed. 
2. Lores and ring around eye naked. 
Herodiones : Herons, Storks, and Ibises, p. 4. 
2'. Lores and ring around eye feathered. 
3. Hind toe long and approximately on a level with front toes (except 
in Cranes which are over three feet long). 
Paludicolee : Cranes, Rails, Coots, Gallinules, etc., p. 4. 
3'. Hind toe short and elevated or absent; bird never over twenty-six 
inches long. Limicolae : Shore Birds, p. 4. 
Read down the key, passing the orders to which it does not 
belong till you come to the order to which it does belong. For in¬ 
stance, if your bird is a duck it has feet fully webbed (1), with two 
webs, three front toes connected (2'), nostrils not tubular (3'), and 
edges of mandibles toothed or serrate (4). It belongs to the Order 
Anseres: Lamellirostral Swimmers. If, on the other hand, the bird 
you want to name is a great blue heron, as it has not fully webbed 
feet, you throw out 1 and all its subdivisions, passing on to 1', — 
feet incompletely or not at all webbed. The first subdivision here 
is 
2. Lores and ring around eye naked. 
Herodiones : Herons, Storks, and Ibises. 
You know if there is a naked ring around the eye, and to find 
what lores means you turn to the diagram of a bird, p. 1. When 
you find that your bird belongs to Order Herodiones, turn to the 
page given (4), where you will find a key to the families in the order.
