GoLDEN Eyr.—Occasionally met with in the fens near Cam- 
bridge. Willoughby mentions in his Ornithology (p. 28.) having 
had one sent him from thence by ‘the name of Shelden. 
Sp.152. A. Fuligula, Vemm. Man. d’Ornith. p. 873. 
TurreD DucK.—I have seen specimens of this bird which were 
killed in the neighbourhood of Cambridge. It is not unfrequent 
in the market. 
Sp.153. A. Leucopthalmos, Temm. Man. d’Ornith. p.876. 
Ferrucinous Ducx.—Dr. Thackeray has a specimen of this 
very rare duck in his collection, which was procured in the Cam- 
bridge market.

RED-BREASTED MERGANSER. — Both this and the preceding 
species are in the collection of Dr. Thackeray, from the Cambridge 
market. It is probable that they only visit this part of the country 
in very severe weather. 
Sp. 156. M. albellus, Temm. Man. d’Ornith. p. 887. 
Smew.—This likewise can only be looked upon as an occasional 
visitant. I find mention in Willoughby’s Ornithology (p. 337.) 
of a specimen that was sent to the author of that work from 
Cambridge; and have myself seen another, a male bird, in the 
collection of Dr. Thackeray, which was bought in the market at 
this place in April 1825. 7
