 breadth throughout ; the nostrils near the middle ; neck 

 long. 



194. Q,. ferus. Wild Swan. — Base of the bill destitute of a 

 protuberance. 



Will. Orn. 272. Sibb. Scot. 21.— Anas Cygnus, Linn. Syst.i. 194 Penn.

 Swan ; JV, Alarch gwyllt — A winter visitant. 



Length 58, breadth 84 inches; weight 25 pounds. Bill nearly 5 inches in 

 length, black, yellow on the sides, at the base, reaching nearly to the eye, and 

 a triangular yellow spot above. Feet black. Windpipe enters a cavity in the 

 breast-bone, and is reflected before terminating in the bronchia?. — (Phil. 

 Trans. Ivi. tab. x. f. 1., and Lin. Trans, iv. tab. xii. f. 1, 2.) Irides brown. 

 Plumage white ; the head and neck sometimes tinged with yellow. The fe- 

 male is less — Nest in rushes, on the margin of lakes. Eggs 5, olive-green, 

 with a white crust — The young have the plumage grey ; the naked space be- 

 fore the eyes livid, and the feet grey, with a tinge of red. A few pairs of this 

 species formerly bred in the Loch of Stennis, Orkney. 



The Cygnus mansuelus, or Tame Swan, a native of eastern Europe and Asia, 

 may be enumerated among our domesticated birds, though it be but half re- 

 claimed. It is larger than the preceding, and is readily distinguished by a 

 black callous knob at the upper base of the bill. This species has been long 

 esteemed as highly ornamental on pieces of water in pleasure grounds.

 than the head. 



* Bill and legs coloured.

 er. — Nest in marshes. Eggs 8, of a dirty white colour. In Lincolnshire these 

 birds are resident ; but, in other places, they retire during the breeding sea- 

 son. This species, as the only permanently resident one, and the young of 



which could be taken and tamed, was reclaimed, at an early period, and is the 

 stock of our domestic geese. Lister, in describing this species, says, u Ros- 

 trum a capite ad mediam fere partem nigrum, deinde subpurpureum, ipso 

 ejus apice nigro." — " Pedes subpurpurei sive carnei coloris ; ungues fere al- 

 bidi excepto medii digiti, qui ex majore parte nigricat."
