Class IL BLACK BILLED AUK. 151 



the auk's, but entirely black. The cheeks, chin, 

 and throat, are white ; in all other respects it 

 agrees with the former species ; we can only ob- 

 serve, that this was shot in the winter, when 

 the common sort have quitted the coasts.* 



When this bird was killed, it was observed 

 to have about the neck abundance of lice, re- 

 sembling those that infest the human kind, only 

 they were spotted with yellow. 



The Alca Balthica of Brunnich, No. 115, a 

 variety in all respects like the common kind, 

 only the under side of the neck is white, is some- 

 times found on our coasts. 



* Mr. Pennant in his ToJir in JVales, seemed convinced, 

 from the observations of the reverend Hugh Davies, that the ' - 

 Black-billed Auk, was no other than the young of the Razor- 

 bill. Y)x. Latham coincides in this opinion j and, in the sixth 

 volume of the Synopsis of Birds, produces many strong argu- 

 ments to confirm the truth of it ; M.X . Montagu '\s, hovi^ever, of ' 

 a different sentiment J and, m\ht Arctic Zoology, M-r. Pennant . 

 has (perhaps inadvertently) given it as a distinct species. Ed.
