there ; in Somersetshire, however, one slightly changing to 

 winter plumage is recorded by Mr. Cecil Smith as killed at 

 Williton in December, 1875. In the London market the 

 young are occasionally to be met with, and during the winter 

 of 1836 Mr, Bartlett purchased two birds, one of which, an 

 adult with a fine black throat, was obtained in the month 

 of January ; the other was a young one. Mr. S. Mummery, 

 of Margate, sent the Author notice that a beautiful specimen 

 was captured on the 2nd of June, 1842, in Sandwich Haven, 

 and this, being a very fine male bird, was preserved, and 

 deposited in the museum at Margate. The late Rev. Richard 

 Lubbock stated that in the year 1832, a fine pair, killed on 

 one of the broads of Norfolk, formed part of the collection 

 of Mr. Penrice ; but most of the examples of this species 

 have been obtained in winter, and were 3'oung birds. To 

 the shores of Lincolnshire, Yorkshire, Durham and North- 

 umberland, the Black-throated Diver is a rare winter visi- 

 tant. In 1830, a fine mature specimen was killed at the 

 mouth of the Tweed, and several young birds on different 

 parts of the coast, and upon the river Tyue. Selby, after 

 examining the bird from which Thomas Bewick engraved the 

 figure of his Lesser Imber, had no doubt that it is the 

 young of the year of this species. More recently examples 

 of this bird have been obtained on many parts of the coast, 

 and also inland. 



To Ireland this Diver has always been a rare visitor, 

 and Thompson only records two authenticated instances ; to 

 which may be added one mentioned by Mr. R. Warren 

 (Zool. 1877, p. 329), a bird exhibiting the full black throat, 

 seen at the mouth of the Moy in April, 1851, and several 

 observed by Mr. H. L. Cox near Dublin in winter and spring 

 (Zool. 1870, p. 484). 



In Scotland the Black-throated Diver was first proved to 

 be a breeding-species by the late Mr. Selby and Sir William 

 Jardine in 1834, and the former gives the following account 

 of their discovery : — "When in Sutherlandshire we found this 

 species upon most of the lochs of the interior. The first we 

 noticed was at the foot of Loch Shin, where we were so fortu-
