just given, however, point clearly to such a communal laying 
on the part of this bird in many instances.

LEACH’S AND STORM PETRELS IN NORTH 
LANCASHIRE AND WESTMORLAND. 
Durine the stormy weather of the last week in October, 
1917, a number of Petrels occurred in North Lancashire 
and Westmorland, some of them a long way inland. Scores 
were seen near Carnforth and several were captured alive. 
Of those I have seen, three were Leach’s (Oceanodroma 
leucorrhoa) and two Storm (Thalassidroma pelagica). The 
last large “‘ wreck ”’ of Petrels in this district occurred in 
November, 1908 (british Birds, Il, p. 282), but in this case 
they were all Leach’s Petrel, which is much the commoner 
of the two on this coast. H. W. Rosinson. 
A NOTE ON THE BRITISH PUFFIN. 
ln British Birds tor June last (antea, p. 5) the authors of the 
Handlist of british birds propose to recognize the Puftin 
which breeds on the coasts of the British Islands, including 
the Fzroes, as a distinct form under the name of F’ratercula 
arctica grabae (Brehm). ‘hey state that the British form 
is very much smaller than the typical form, the wings 
measuring 158-166 in British birds as against 160-177 in a 
large series ot F’. arctica arctica. 
jn order to test these conclusions we have recently 
examined and measured the examples of Puftins in the 
Biitish Museum. I will here give our results of the 
measurements of the wings of adults in millimetres— 
(1) Six adults from Spitsbergen: ¢ 181; 9 188, 185; 
o 155, 184, 177. Average 183°3. 
(2) Four adults trom N. Norway: 6,161, 158; ¢ 157, 
156. Average 158, 
(3) Seven adults trom the Feroes: ¢ 163, 160, 158; 
2 156; o 162, 155, 153. Average 158°5. 
(4) Four adults trom Orkney, Shetland and St. Kilda : 
6 157, 153; 2163; o 160. Average 158:2. 
(5) Six adults trom Yorkshire coasts: 2 157, o 163, 
160, 161, 156, 151. Average 158. 
(6) Ten adults trom Pembrokeshire and Man: ¢ 158, 
157; 92 15Y, 156, 155, 154, 152, 152, 148; o 160. 
Average 156. 
(7) Six adults trom N. America (Greenland to Fundy) :
