76 Mr. A. G. More on the Distribution of Birds 
‘ Zoologist ;? but Mr. Henry Milner has kindly informed me that 
the bird was not found breeding there, and only a single speci- 
men was purchased on that occasion. 
Uris GRYLLE (Lath.). Black Guillemot, 
Provinces [VI.] [VII.] XII. XIV.-XVIII. 
Subprovinces (17), (18), 25, 28, 29, 30-38. 
Lat. 54°-61°. Scottish” type, or Northern. 
In the time of Montagu a few pairs used to breed annually at 
Tenby ; and it is possible that the bird is not yet extinct in this 
locality, as Mr. Tracy includes it in his list. Pennant mentions 
Llandudno and Anglesea; and Mr. J. F. Crellin finds the Black 
Guillemot breeding in small numbers in the Isle of Man. It 
breeds also on the east coast of Scotland, at St. Abb’s Head (Rev. 
J. Duns), on the Bass Rock; on the Isle of May (Sir W. Jar- 
dine) ; at Stonehaven (Dr. J. A. Smith) ; and is pretty generally 
distributed in the north and west of Scotland. 
Obs.—The Little Auk (Arctica alle) is recorded as having been 
seen by Macgillivray on the Bass Rock during the month of 
May, and was reported to him as breeding at St. Abb’s Head ; 
and in Thompson’s ‘ Birds of Ireland’ (vol. i. p. 220), mention 
is made of four Little Auks seen at Ailsa Craig on the 19th of 
May; but the eggs have not been found in either locality. 
Auca IMPENNIS (Linn.). Gare-fowl, or Great Auk. 
Province [XVIII.]. 
Subprovinces (36), (37 ?). 
Lat. 59°-60°. ‘Scottish ” type, formerly. Not in Ireland. 
Spoken of positively by Martin as having formerly bred on 
St. Kilda ; and according to the information procured in the Ork- 
neys by Bullock, and published by Montagu, a pair of this species 
annually visited Papa Westra up to the year 1812, when the 
specimen now in the British Museum, and the last observed 
there, was shot. 
Mr. John Macgillivray, in 1840, found that the bird was well 
known to the inhabitants of St: Kilda, but had not been observed 
to breed there for many years back.
