1880.] SPECIES OF ANATIDjE. 511 



Knowsley sale in 1851. According to Hartlaub it merely differs 

 from S. vielanonota in its smaller size. 



13. Sarcidiornis carunculata (Licht.). American Wattle- 

 Duck. 



Sareidiornis carunculata, Scl. P. Z. S. 1876, p. 094, t. 68. 

 Hub. South America. 



See my notes (above referred to) on this species, which was first 

 received in 1876. 



Genus Cairina. 



14. Cairina moschata (Linn.). Muscovy Duck. 

 Cairina moschata, Scl. et Salv. P. Z. S. 1876, p. 378. 

 Hab. Central and South America. 



The domestic " Muscovy Duck," as it is called, has long been 

 introduced into Europe, and breeds readily {inter se), besides hybri- 

 dizing freely with the common Domestic Duck. 



In 1851 I find a record of "Wild Muscovy Ducks" having been 

 received from America, and noticed as new to the Collection. We 

 have recently (May 6, 1880) received three examples from Paraguay, 

 which I believe to be probably of the wild race. 



Genus Tadorna'. 



15. Tadorna cornuta (Gm.). Common Sheldrake. 

 Tadorna vulpanser, Gould, B. G. Brit. v. t. 1 1 ; Scl. P. Z. S. 1864, 



p. 189. 



Hab. Europe and North Asia. 



The Sheldrake is in the earliest list, and in former years bred 

 frequently in the Gardens. It is not, however, a ready breeder in 

 captivity, and requires special treatment.

Tadorna radjah, Gould, B. Austr. vii. t. 8 ; Scl. P. Z. S. 1864, 

 p. 190. 



Hab. North Australia and Molucca?. 



This beautiful Sheldrake would form a fine addition to our intro- 

 duced Water-fowl. It would, I should say, be easilj' obtainable in 

 Queensland. 



17. Tadorna rittila (Pall.). Ruddy Sheldrake. 



Casarca rutila, Gould, B. G. Brit. v. t. 12 ; Scl. P. Z. S. 1864,
