seventh and eighth, and that occasionally examples occur in 
Europe which agree in wing formula with this form, but un- 
fortunately he gives no data; Hartert (of. czz., p. 589) observes 
that “isolated specimens are not to be distinguished from the 
Western form, and where the two forms meet the difference 
apparently is often not well marked—even in Siberia 
examples with a long second primary occur.” 
Be the status of this bird what it may, the fact remains 
that no Lesser Whitethroat with that wing formula which 
alone characterises the Eastern bird has hitherto been 
recorded as occurring in the British Islands, 
Hartert gives the general distribution of afinzs as 
follows :—Breeds in Siberia, northwards to the limits of 
forest growth, east to Transbaikalia and Manchuria, and 
south apparently to the Thianshan and Altai Mountains 
and winters in India and Ceylon, migrating through 
Turkestan, East Turkestan, East Persia, Afghanistan, and 
Baluchistan. 
The Yellow-legged Herring Gull was observed alone on a 
stubble field above the South Haven on 28th September. It 
was most distinctly seen in bright sunlight, and its identity 
could not have been more satisfactorily established if the 
bird had been in our hands. On mentioning this Gull to 
one of the natives who is interested in birds, it was ascer- 
tained that it had been observed by him on several occasions 
during the previous six weeks and was always alone. 
Only two records of the previous occurrence of this bird 
in Britain are known, namely one from Norfolk in November 
1886, and another from Dover in April 1904. The species 
is a native of maritime areas from the Bay of Biscay to 
the Azores, and throughout the Mediterranean region to 
the Caspian Sea and even to Lake Baikal. 
Other interesting birds which came under notice include 
the Scarlet Grosbeak, the Blue Headed Wagtail, the Blue- 
throat, Hoopoe, and Great Snipe.
