THE ZooLoGIst—SEPTEMBER, 1875, 4605 
Bulwer's Petrel (Thalassidroma Bulweri).— Only known 
from Greenland by a specimen received thence at the Museum 
of Leyden (Schlegel, Mus. Pays-Bas, Procellarie, p. 9), from 
the Moravian missionaries. 
“* Puffin (Fratercula arctica?). “ Killangak.”—Puffins seem to 
be nowhere common in Greenland, and are said by Holb6ll not to 
breed further south than lat. 63° 80’ N., which seems a questionable 
assertion. Whether two species are found there is also a doubtful 
matter.* The puffin of Spitsbergen appears to the compiler to be 
justifiably separable from that which inhabits more southern stations 
in Europe on account of its much larger size, and to it should 
probably be assigned the name of F. glacialis (Leach), but the type 
of that supposed species is said to have been received from Green- 
land, whence Cassin also says he has seen it. On the other hand, 
Prof. Reinhardt says that all the puffins he has examined from 
Greenland belong to the common species F. arctica. The difference 
between the two is admittedly only one of size, though that 
difference is great. A series of specimens which would help to 
clear up this matter is something to Se desired. 
*Black Guillemot or Greenland Dove (Uria grylle). “ Serbak,” 
“Sergvak”; (in summer) “ Kernekungojuk,” “ Kernektarsuk”; (in 
winter) “ Kakortungojuk.”— Very numerous on both coasts of Green- 
land, and said to remain longer than any other bird. Plentiful also 
on Melville Peninsula, but more rarely seen in the Polar Sea. The 
distribution of the various species of black guillemot (which it 
may be observed is, except in the breeding plumage, anything but 
“black”) is matter deserving of the fullest attention. The ordinary 
form from Spitsbergen is of slender build, and has the wing-spot in 
the adult purely and entirely white. That of the Norwegian and 
British coasts (U. grylle, vera) is stouter, and has the white feathers 
of the wing-spot with black at the base, but this colour does not 
show outwardly. That of the North Pacific (U. Columba) has a 
distinct black bar across the wing-spot, while another form (U. 
Carbo) is altogether black. Now a specimen not to be distinguished 
from the typical U. Columba was obtained in the Spitsbergen Seas 
by Dr. von Heuglin, and Holbdéll says he has seen in Greenland an 
entirely black example, which, therefore, may perhaps be regarded 
1 The tufted puffin (Fratercula cirrhata), a bird of the north-west coast of North 
America, is said to have been received from Greenland (Méschler, Journ. f. Orn. 1856, 
p. 385); but there is most likely some mistake about it,
