WAITE: VERTEBRATES OF THE WESTERN AINSTY. 10g 
Larus ridibundus Linn. Black-headed Gull. Small flocks 
of Gulls often pass over in winter, but usually at a great 
height. ‘This is the commonest Gull which visits the district, 
and examples have been shot at several places. I obtained a 
young bird in its first year’s plumage at Walton, on the 25th 
June, 1890. (Naturalist, July, 1890, p. 210). 
Larus canus Linn. Common Gull. Occurs, but not nearly 
so commonly as L. ridibundus. Stragglers are occasionally 
obtained during boisterous weather in late autumn and winter. 
They are usually birds of the year, and when not on the wing, 
they generally confine themselves to recently ploughed fields. 
Larus argentatus Gmel. Herring Gull. ‘his species has 
occurred in the district, though very rarely. It has been shot at 
Wilstrop by Mr. John Harrison. 
Rissa tridactyla (Linn.). Kittiwake. Has occurred during 
winter, and examples have been shot at several places in the 
district. 
Stercorarius pomatorhinus (Temm.). Pomatorhine Skua. 
An example was obtained at Towton in October, 1879, and a 
second, now in the possession of the Rev. J. W. Chaloner, was 
shot by him at Newton Kyme about the same time. This was 
during the great irruption, when scores of specimens were 
obtained on the Fast coast of England, and individuals were 
shot very far inland. 
Mergulus alle (Linn.). Little Auk. The Rev. J. W. Chaloner 
records the fact that an example was picked up dead by the 
mowers in a meadow at Newton Kyme, on the 16th July, 1885. 
(‘ Naturalist, 1885, p. 299). He tells me that the bird had been 
dead so long as to be of no use for a specimen, and it was thrown 
away. 
Fratercula arctica (Linn.). Puffin. One was shot on the 
Wharfe at Wetherby in November, 1870 (Wesley, ‘ Field,’ 
November 19th, 1870). : 
Colymbus glacialis Linn. Great Northern Diver. Ina MS., 
dated 14th May, 1880, Mr. John Emmet, of Boston Spa, 
writes :—‘ Mr. Chaloner considers this bird the scarcest ever 
taken at Newton Kyme. He took three birds about the year 
1826 or 1827.’ In looking over my proofs, Mr. Chaloner tells 
me that he saw the birds but did not obtain them, and adds 
that the date was 1818 or 1819. 
Colymbus septentrionalis Linn. Red-throated Diver. The 
___ Rev. J. W. Chaloner, of Newton Kyme, shot an example there, 
April 28
