BLACK GUILLEMOT. 725 



Bay near the Pier at Scarborough, was taken to Mr. W. J. 

 Clarke, taxidermist, of that town. It proved by dissection to 

 be a male : total length 18 inches, expanse of wings 24J inches, 

 wing from carpal joint to tip slightly more than 8 inches. 

 Mr. Clarke at once noticed that it varied from the ordinary 

 British type, and forwarded the specimen to Mr. J. E. Harting, 

 who pronounced it to be U. hruennichi, and afterwards 

 exhibited it at a meeting of the Linnean Society in January 

 1895 (Proc. Linn. Soc, 17th January 1895). 



In the January following, as I learn from Mr. Brown of 

 Filey, several were picked up on the beach at that place. 

 One of these, which was a male, measured 19I inches in length ; 

 from the carpal joint to the end of the longest primary, SJ 

 inches ; total expanse of wings, 28^ inches. The tarsi and 

 toes were light yellowish olive, webs dirty brown. The second 

 was a female, and measured in total length i8| inches ; wing, 

 7I inches ; total expanse, 26 inches (Harting, Field, 9th 

 February 1895 ; and ZooL 1895, pp. 70-71). Another 

 example, procured near Flamborough Head in November 

 1899, is now in the collection of Sir Oswald Mosley of Rolleston 

 Hall, Derby. 



The latest occurrence was on 28th October 1902, when 

 Mr. Joseph Morley of Scarborough wrote informing me that 

 he had shot a Brunnich's Guillemot at sea, about two miles 

 from the Castle Foot. 



The figures of this species in winter plumage, depicted in 

 Lord Lilford's work on " British Birds " (part 32), were drawn 

 from the specimens obtained in Yorkshire in the winter of 

 1894-95. 



It is possible, indeed very probable, that this bird is often 

 overlooked, or confused with the Common Guillemot, from 

 which it differs in having much blacker plumage, lighter 

 coloured legs, and a stouter bill with a white line on the 

 upper mandible.
