BLACK SWANS. 



Cygnus atratus, Meyer. 



Natives of Neu' South Wales, but are suflBciently domesticated to breed in this 

 country. — These birds were reared by SirRobert Heron, at Stublon in Lincolnshire, and 

 presented by him to the Society. They now breed freely in the menagerie. Others 

 have been presented by Lord Fit^william, Lord Milton, and R. W. Hay, Esq. 



CEREOPSIS GEESE. 



Cereopsis Novae Hollandia^, Lath. 



A beautiful species from New Holland, which there is reason to hope may be do- 

 mesticated in this country. -Four pairs were included in the splendid donation made 

 to the Society by His Majesty. They have reared young ones every year since they 

 have been i'.i the Society's possession. 



SHIELDRAKES. 



Anas Tadorna, Linn. 



These are found plentifully on parts of the coasts of England, where they breed 

 principally in rabbit-holes in the ground. They inhabit similar places in the Western 

 parts of Europe. — Part of the birds here exhibited were presented by the Council of 

 the Horticultural Society, in whose Garden one pair of them was hatched and reared 

 in 182/. Other young ones have been hatched in their present situation. 



WILD DUCKS. 



Anas Boschas, Linn. 



BARNACLE GEESE. 



Anser leucopsis, Bechst. 



Breed in the Arctic countries, and go to the South in the winter, both in Europe and 

 America. Are seen in winter on our Northern and Western coasts. It was to this 

 species that in the darker ages the marvellous origin was ascribed of its being formed 

 in the shell called the Barnacle. 



WIDGEONS. (Male and Female.) 

 Anas Penelope, Linn. 



BRENT OR BRAND GEESE. 



Anser Bernicla, . 



Like the Barnacle Geese, vvith which, in consequence of their specific name, they 

 are often confounded, they visit our shores in the winter, but in much greater numbers. 

 They retire in the spring to the colder regions of the North, even to within the Arctic 

 Circle, and breed in great numbers on the Islands in the Polar Sea, migrating after- 

 wards into Europe and America. 



AMERICAN WOOD, or SUMMER TEAL. (See page 14.) 

 Anas sponsa, Linn. 



The Crotvned Cranes and other Wading Birds from the large Aviaries are 

 turned into thi.s Enclosure during the day-time. 



The remainder of the Aquatic Birds will be found in the Enclosires (15), 

 (16), (25), (28), and (39). 



In descending from the Terrace, the building which immediately presents 

 itself is the Llama- House (5). In this are for the present exhibited specimens 

 of the 



DROMEDARIES. (Male and Female.) 

 Camelus Dromedarius, Linn. 



The term Dromedary, though commonly applied to the one-humped or Arabian 

 Camel, is scarcely a correct expression, since it is applied to a particular breed 

 of these animals, of great swiftness, and used for purposes of dispatch. There is also 

 a light breed of the two-humped Camel, celebrated in China for its extraordinary 

 rapidity. 



Of the Genus Camelus there are two distinct species; one, the Bactrian or two-
