THE BLACK-THROATED DIVER. 201 



In a lecture on native birds, delivered some years ago by Mr. 

 R. Ball, in Dublin, lie stated, that a great northern diver, shot on 

 the Irish coast, and in the possession of Sir Philip Crampton, Bart., 

 was found, when killed, to have an arrow headed with copper, 

 sticking through its neck. He remarked that the bird had pro- 

 bably been struck with this arrow by an Esquimaux on the 

 Coppermine river, and was indicative of, the extensive flight of the 

 species. 



The ^ Penny Magazine ' for August 1839 (p. 319) contains an 

 original and iuterestiug article on the mode of huiiting this diver 

 in North America. Audubon gives a very full account of the 

 bird, in the foui'th volume of his ' Ornithological Biography,^ 

 p. 43. 



THE BLACK-THROATED DIVER. 



Lesser Imber (young). 



Columbus arcticus, Linn. 



Is extremely rare. 



A SPECIMEN of this bird, which I recorded in the ' Zoological 

 Proceedings' for 1837 (p. 54), was obtained with two other 

 Colymhi {C. septentr'wnalis) in Larne Lough at the end of De- 

 cember 1831, by Dr. J. D. Marshall, who remarked that they 

 were very tame compared with brent geese, cormorants, and other 

 sea-fowl. The following notes were made on this bird after its 

 being preserved : — Length (total) 25^^ inches ; of wing from 

 carpus to point of quills, lOj in. ; of bill from rictus to point, 83- 

 in. ; of tarsus, 2f in. ; of middle toe and nail, 3i in. Sides of 

 the neck marked with dark longitudinal striae, which likewise ap- 

 pear, but fewer in number, in front of the neck ; throat pure white. 

 The only difference between this specimen and descriptions of C. 

 arcticus in the fu^st year, is, that the base of its lower mandible 

 appears channelled, and might perhaps be called thickened in the 

 middle, though most obscurely so. The bill in profile is just that
