vou. x1] , NOTES. 165 
Norway, collected by A. E. Brehm in June, 1860, have wings 
measuring as follows: 33 168°5, 177, 92 166, 167 mm. 
With these I can compare : eight skins collected by me on the 
rocky islets near Herm, Channel Islands, on May 3rd, 1899 : 
$3 155, 155, 157, 163, 164 mm., 992 155, 157-5, 165 mm. 
Belmullet, County Mayo, Ireland, May to July, 1863: 3 160, 
22 157, 159, 160°5. Staffa, June (sex ?), 162. St. Kilda 
eex 2); 156, 157, 157,:157 mm. _Feroes: ¢3 157, 163; 
sex ¢?: 157, 158, 158 mm. 
The wing of the one useful specimen from Norway in the 
British Museum measures, as correctly stated by Messrs. 
Sclater and Praed, 161 mm., in fact, I only made it 160°5 
mm. Certainly this is less than my measurements from 
Tring specimens, but we cannot throw over a subspecies 
because one specimen stands out from the rest. Now the 
wings of Bear Island birds, specially identified by several 
good ornithologists and said to be identical with Norwegian 
ones, have, according to le Roi, wings of 160 to 176 (average 
168) in eight males, 158 to 168 mm. in five females (average 
163°6), thus being obviously larger than British and French 
Puffins. 
Messrs. Sclater and Praed do not mention the bills. It 
is true that they are variable, but at the same time—apart 
from the general, but not constantly larger size of Iceland and 
South Greenland, as well as Labrador birds—the bills of Nor- 
wegian specimens measure in length 45-51, height 31-41 mm., 
while British and Herm birds have the length 43-48, height 
34-37 mm.—even here generally, though not constantly, 
smaller dimensions in grabe. 
In my unpublished MS. I have unquestionably separated :— 
1. Fratercula arctica naumanni Norton (glacialis auct.) 
from Spitsbergen. This form is apparently also 
found on Nova Zemlia, and it is said to inhabit 
Jan Mayen and northern’Greenland, while “* arctica ” 
is found in southern Greenland ; these latter state- 
ments require, however, confirmation, especially 
as in Jan Mayen smaller and larger birds are said’ 
to occur ! ; 
2. Fratercula arctica arctica (L.) Norway, Bear Island 
and Sweden. With this form I have provisionally 
and doubtfully united the birds from Iceland, 
southern Greenland to Ungava and Fundy Bay, 
but I have given careful measurements and said 
that possibly the birds from Iceland to Labrador 
might form another, intermediate subspecies, which 
would then be called F. a. deleta. This form is
