in 1853, I have since received a third from Greenland in 1855, 
the examination of which has confirmed me in considering the 
bird a distinct species. It is not only its much larger size 
which distinguishes the Greenland bird from its European rela¬ 
tive, but also the very sensible difference in the shape of the 
bill. In P. holbcellii it is, comparatively to its length, not so 
high at the base as in P. griseigena, and of course much more 
gradually tapering towards the point. In my opinion, P. hoi - 
bcellii indeed differs more from P. griseigena than many other 
North-American birds, now generally admitted as distinct, do 
from the allied European species, as, for instance, Anas caro- 
linensis from A. crecca , or Fuligula affinis from F. marila.

Only a few young birds, obtained in the southern part of 
Greenland.

The “ GeirfugP* now being nearly extinct, it would be in Vain 
to hope to meet with it on the coast of Greenland ; but even 
formerly, when the bird was still numerous at its breeding- 
places, it seems to have visited Greenland only in winter, and in 
limited numbers, chiefly of young birds. In the present century, 
a specimen is known to have been killed at Disco Island in 1821, 
and one more may perhaps have been captured some years 
earlier; but the accounts of other instances in which the bird is 
said to have been obtained in Greenland are hardly to be con¬ 
fided in. 
89. Alca torda, Linn. 
90. Eratercula arctica (Linn.). 
91. *Fratercula glacialis , Leach. 
All the Puffins which I have received from Greenland I con¬ 
sider to be of the common species. As Mr. Cassin, however, 
mentions (Rep. Expl. ix. p. 903) that he has seen specimens of 
the F. glacialis from thence, I do not hesitate to include this 
species also in the Greenland Avifauna ; but I think it must be 
considered an accidental visitor.
