It is usual to divide the Anseres into four groups, which some 

 authorities rank as orders ; these are : Lamellirostres (=Un- 

 guirostres Chenomorphae) : edges of the bill furnished with thin 

 plates or lamellae. Steganopoda ( = Totipalmatae, Dysporomor- 

 phaj) : all the toes united by a membrane. Longipennes : hind 

 toe free ; wings long [from these Procellariidse were separated as 

 Tubinares ; Aptenodytidse are the Spheniscomorphse of Huxley]. 

 Pygopoda (=Brevipennes, Urinatores): hind toe sometimes ab- 

 sent ; wings very short. Phaenicopterus is placed by Huxley be- 

 tween the anserine birds and the storks and herons, under the 

 name of Amphimorphze. Garrod makes it a subfamily of bustards. 

 Its webbed feet is said by Owen to be an artificial character.
