2134 Birds. 



which, in the case of the commoner birds, sometimes amount to a great many. Most 

 of those duplicates are kept separately, the systematic collection embracing, besides 

 the eggs of one nest, or the number laid by each bird, only one or two of the most 

 striking varieties. 



" This Catalogue is intended to apply only to such a collection ; according to which 

 arrangement all the eggs of one nest will, of course, bear the same mark. If e. g. a 

 collector possess several eggs of the common buzzard, viz. three found in one nest in 

 Westmoreland, one bought of a dealer, and the other obtained in exchange ; every one 

 of the three eggs found in the same nest will bear on the ticket, 17 a; the egg pur- 

 chased, 17 b ; and the egg procured by exchange, 17 c ; and the particulars relating 

 to those several specimens will be entered in the Catalogue under the 17th species, 

 thus: — 



"17sp. Falco Buteo, Lin. The common Buzzard. 



" 17 a. Three eggs found in one nest, in the wood at in Westmore- 

 land. April 18 . 



14 17 b. ? Purchased of N dealer, at . 



" 17 c. Exchanged with N for the eggs of N. ." 



Ornithological Observations in Norfolk for March, 1848. — Another example of the 

 hooper (Cygnus ferus) was killed about the 25th of February. A very fine adult male 

 gyr falcon was shot about the 24th of February, at Beeston, near Cromer : this bird 

 was very fat, and showed no marks of having been in confinement ; it measured, when 

 stuffed, 23£ inches from the point of the beak to the tip of the tail : there is of course 

 now no further reason for excluding this beautiful species from the list of Norfolk 

 birds (see Zool. 1301). Early in March, three adult peregrine falcons (two males and 

 one female) were taken in the neighbourhood of Thetford. On the 11th of March an 

 Egyptian goose — apparently a wild bird — was shot upon Ormesby Broad, and a few 

 days afterwards another specimen was shot in the same neighbourhood. On the 25th, 

 a tufted drake, in company with which were two ducks, was shot on the river Wensum 

 at Cossey : this seems to be rather an inland locality for a member of the oceanic fa- 

 mily of ducks at such an advanced period of the spring ; but it is possible that the 

 birds were resting on their northerly migration, upon which occasion they more fre- 

 quently cross the land than in their southerly autumnal movements (Zool. 1390). — /.

On the Nomenclature of Birds. — Some months since my attention was attracted by 

 certain remarks from your correspondent, the Rev. James Smith (Zool. 1909), upon the 

 subject of nomenclature, in which the name Fuligula ferinoides — given to a species 

 of duck lately separated from the common pochard (F.ferina) — was somewhat severely 

 criticized. The subject has again been referred to (Zool. 2063) by your correspondent 

 Mr. Newton. It appears, as might have been expected, to have occurred to both these 

 gentlemen, that in criticizing the old name it was necessary to propose a new one ; 

 and, anticipating that they would do so, and confidently looking for some valuable 

 suggestion upon the subject, I commenced the perusal of their remarks with great in- 

 terest and attention. Assuming that the names ' Paget's pochard ' and * Fuligula
