 Anasflavirostris, Smith, 111. S. Afr. Zool., Aves, t. 96. 



Hab. South Africa. 



The Guilbec, or Yellow-billed Duck, was first obtained at the 

 Knowsley sale in 1851. It bred in 1859 and 1860; and we have 

 supplied some of the Continental gardens with our produce. But 

 I am not quite sure, I regret to say, that our present stock of this 

 Duck is pure-bred.

39. Anas pffiCiLORHYNCHA, Penn. Spotted-billed Duck. 



Anas poecilorhynclia, Gray, Ind. Zool. i. t. 67. 



Hab. India. 



A single example of this fine Duck was obtained at the Knowsley 

 sale in 1851, but we lost the species ; and it was not again intro- 

 duced, I believe, until 1868, when we received several males from 

 the Babu Rajendra Mullick. In 1872 we received females from Mr. 

 E. Buck (see P. Z. S. 1872, p. 729); and in 1874 the first pure- 

 bred birds were hatched. The species may now be considered fairly 

 established, and is also found in several of the Continental gardens.

I have not yet seen this close ally of the last species living in Europe.

Anas sparsa. Smith, 111. S. Afr. Zool., Aves, t. 97. 

 Hab. South and East Africa. 

 Not yet introduced. 



42. Anas castanea (Eyton). Chestnut-breasted Duck. 

 Anas punctata, Gould, B. Austr. vii. t. 11. 



Mareca castanea, Eyton, Mon. Anat. p. 119, t. 22. 



Hab. Austraha. 



In June 1870 we purchased a single male example of the Austra- 

 lian Duck along with a lot of other animals from the same country. 

 Whether the female obtained in 1865 (and credited to this species 

 in the Cat. of Animals) really belonged here or to the next species, 

 I cannot at present say.
