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

 species formerly bred in the Loch of Stennis, Orkney. 



The Cygnus mansuetus, 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 biU. This species has been long 

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

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, " Ros- 

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

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

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