The Circus cineraceus has been met with from the south to the 
north of England, but has not occurred in Scotland, unless in the 
instance mentioned at p. 83. Flanus furcatus is an American 
(N. and S.) species, which has been taken once in Scotland and 
once in England. The Neophron percnopterus , which inhabits 
the south of Europe, has but once been procured in Great Britain. 
Surnia funerea is included in the British list, from a single indi- 
vidual captured on board a vessel off the coast of Cornwall, as 
recorded by me in the Proceedings of the Zoological Society for 
1835, p. 77. It inhabits the northern parts of Europe and North 
America. Noctua passerina and N. Tengmalmi are only occasional, 
and very rare visitants to England ; in Scotland, they have not 
been noticed. The former is chiefly a native of the more southern 
portion of Europe, not having been seen beyond 55° north lati- 
tude, according to Temminck. The latter inhabits more especially 
the northern parts of that continent, but has been obtained on 
the southern side of the Alps. It is common in North America. 
The distribution of Vultur fulvus , and Aquila ncevia , is treated 
of under those species, in the preceding pages. 
The difference between the species of raptorial birds enumerated 
in the respective lists of Great Britain and Ireland, arises, with 
the exception of Circus cineraceus (a species resorting to England 
regularly in the summer), from mere accidental visitants. If we 
pause for a moment to consider the probability of the occurrence
