free, articulated higher up on the flank, without a membrane, or having 

 only the rudiments thereof. Wings of middle size ; the first quill either 

 as long as the second or rather shorter. 



Temminck divides the genus into four sections. 1. The Goose ; 

 2. The Swan ; 3. The Duck. A. Ducks having the hind claw 

 naked. B. Ducks having the hind claw covered with a loose mem- 

 brane.* 



ANATIDiE (Leach.)— * Birds of the Duck, Goose, and Swan

ANORTHURA (Rennie.)— * Wren, a genus thus characterise d.- 

 Bill slender, slightly compressed, notched, curved or rarely straight. 

 Nostrils at the sides of the base, oval, and half covered by an arched and 

 naked membrane. Wings short, rounded, having the first quill very 

 short, the second considerably shorter than the third : the fourth and 

 fifth are of equal length, and the longest in the wing. Tail short, rather 

 rounded and carried erect. Legs strong : shank of the same length as 

 the middle toe. Toes three before and one behind. The outer toe 

 joined at its base to the middle one ; the outer and inner being equal in 

 length.

 notion that the Wrens live in caverns, as the ancient people named 

 Troglodyte are recorded to have done. 1
