We have followed Mr. Stephens anil Mr. Gould in preserving to this species the name of ferus, 

 and to one of the foregoing A. segetum, as being better known than those of Dr. Fleming used by 

 Mr. Selby. The above bird arrives here in the winter in great numbers, and, according to Tcm- 

 minck, the distribution of it is very wide, being over Europe, Nubia, and part of Western Africa, 

 inhabiting lakes and marshes. 



Breeds in the north, and formerly reared its young in this country, laying about ten eggs of a 

 white colour. 



ANSER GUINEENSIS. 



Ans. — Griseo-cinereus : subtus albus, tuberculo ad basin rostri, 



SWAN GOOSE. 



Griseous-cinereous goose; below white, with a tubercle at the base of the bill. 



Length 39 inches. 



Above cinereous grey, with the edges of the feathers light grey ; from the occiput down the 

 back of the neck runs a dark brown streak to the back ; fore part of the neck, breast, and abdomen, 

 dirty white ; bill (which has a large knob at its base) greenish white colour ; legs orange. 



The female is less than the male, and with the colours not so distinct ; the knob at the base 

 of the bill is also smaller.

Said to inhabit (in a wild state) some parts of Siberia and Kamsehatka, and to have been originally 

 brought to this country from Guinea, but are now to be found in a semi-domesticated state in most 

 parts of Europe. 



This species crosses freely with the common tame goose, and their offspring are again productive. 



Trachea of large diameter, and very much in this part, as in its whole anatomy, resembling 

 the true swans. The trachea descends between the rami of the os furcatum. and is joined to the 

 point from whence they diverge by a strong ligament, as in the black swan.
