tion, they are timid and extremely gentle, and never attempt to 
molest any of the wild fowl confined in the same pond with them, 
though all of these are their inferiors in strength and size. Their 
call, chiefly uttered at the migratory periods, is a low deep-toned 
whistle, once repeated. On the water, the carriage of the Cygnus 
Beivickii is intermediate in its character between that of the mute 
swan and common goose ; but if these birds exhibit not the grace 
and majesty of the former on this element, they appear to much 
more advantage on the land, where, by choice, they spend the greater 
portion of their time. 
The Museum of the Royal Dublin Society contains a specimen 
of the Cygnus Beivickii (though not so labelled) which was shot in 
November 1830, on the west of Ireland. It exhibits the rust-co- 
lour on the head, indicative of immaturity. In the collection of 
William Massey, Esq. of the Pigeon House, Dublin, I recognized 
another individual of this species, in the immaculate plumage of 
maturity. This was, along with a second specimen, killed by Mr 
Massev, out of a flock of five, in Dublin bay, on the 18th December 
1829. The Cygnus Bervickii has not before been recorded as oc- 
curring in Ireland. 
I subjoin the following notes, made subsequent to June 3, 1834, 
when the last part of this paper was read : 
LARUS SABINII. 
" A third specimen of this bird occurred last autumn in Ireland. 
It was shot on or about September 15, 1834, on the shore of Belfast 
Bay, near Claremont, the residence of Mr Clewlow, in whose pos- 
session it now is. It is a young bird of the year, and in plumage 
similar to the other two individuals of this species, which I had the 
satisfaction of announcing to the Linnaean Society, last year, as 
having been obtained in Ireland."* The dimensions of this bird, 
taken in the same manner, and compared with those of the indivi- 
dual above described, exhibit but one difference at all worthy of 
notice ; its first quill being longer than the second, though the se- 
cond slightly exceeds the first, in the latter specimen. 
CYGNUS BEWICKII. 
June 1834. On a fine sheet of water, in the demesne of the 
Marquis of Sligo, at Westport, county of Mayo, I observed a swan
