Hab. Antarctic America. 



A single male of this beautiful Duck was received in 1867. In 

 1870 we obtained three pairs from Mr. Weisshaupt's Chilian 

 collections, but they did not breed until 1873.

G. Subfam. VI. FULIGULIN^. 

 Genus Fuligula. 

 a. Species ArcticcB. 



1. Fuligula rufina (Pallas). Red-crested WhistHng Duck. 

 Branta rufina, Gould, B. G. Brit. v. t. 22. 



Hab. South Europe, North Africa, and Western Asia. 



We first received a single male of this beautiful Duck from our 

 Corresponding Member Mr. E. C. Buck, in 1874. In 1876 the 

 same gentleman most liberally presented us with twelve males and 

 six females of the same species, obtained in the Punjaub, 



In spite of every care lavished upon several pairs of this Duck, 

 selected out of the lot thus acquired, they have hitherto refused to 

 reproduce inter se. But last year five curious hybrid Ducks were 

 bred in the Society's Gardens, which seem certainly to be the 

 produce of a cross between this species and Metopiana peposaca, 

 as examples of these two species were in the pond in which they were 

 hatched, although it is not certainly known of which sex the parents 

 were respectively. 



2. Fuligula cristata (Leach). Tufted Duck. 

 Fuligula cristata, Gould, B. G. Brit. v. t. 23. 

 Hab. Palsearctic Region. 



The Tufted Duck occurs in the earliest list (1831), and is a 

 familiar inhabitant of our "Three-island Pond." Up to 1848 it 

 bred pretty regularly in this situation. In 1849 it hybridized with 

 the White-eyed Duck, and the hybrids thus produced continued to 

 breed either inter se or with one of the parents until 1861.
