Cuass Il. BLACK BILLED AUK. 
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 Tour in Wales, 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. Dr. Latham coincides in this opinion; and, in the sixth 
volume of the Synopsis of Birds, produces many strong argu- 
ments to confirm the truth of it; Mr. Montagu is, however, of 
a different sentiment; and, in the Arctic Zoology, Mr. Pennant 
has (perhaps inadvertently) given it as-a distinct species. Ep.
