NEW HOLLAND CEREOPSIS. 69 



measuring six inches in length, and the bare space 

 above the knee, less than one inch : the toes are not 

 cleft, but, as before-mentioned, in the generic cha- 

 racter, they are united by a membrane which has its 

 edges very deeply notched ; the hinder toe is not 

 particularly small. 



Native of New Holland. Three specimens only 

 are known, which are deposited in the national col- 

 lections of London, Paris, and Berlin. 



STIRPS III. 



Rostrum lasi lathis quam altum, lateribus laminato-dentatis; tarsi 



breves ; pollex simplex. 

 Beak broader than high at its base, with its edges laminato-den- 



tate; tarsi short ; hind toe simple. 



THE Ducks of this stirps are generally of a slen- 

 derer form than those of the fifth ; their beak is more 

 equal, their neck and wings longer ; the tarsi shorter 

 and less compressed ; the legs placed more forward 

 on the abdomen, and the hind toe is destitute of 

 a membrane. They walk better than those birds, 

 but with less freedom than the Swans and Geese ; 

 swim well, but do not dive. They feed upon aquatic 

 plants and their seeds, as well as upon fishes and 

 other small animals.
