intensity in different individuals. Both sexes take their turn 
in hatching; their cries and their flight are exactly alike; 
both fly at the intruder with equal courage, and, as far as 
I could observe, from examining a large number of specimens, 
they are similar in size and colour throughout the breeding 
season. A character, however, by which the sexes may be almost 
invariably distinguished, is the superior length of the long tail- 
feathers in the male. I have several times shot one bird of a 
pair and found its sex agreeing with my expectation from having 
observed this distinction when in flight. In the female, the two 
long tail-feathers are six inches, or a shade more, exceeding the 
shorter, while in the male there is a difference of at least seven, 
and in some cases eight inches in their respective lengths. In 
Polaris Bay, Dr. Coppinger observed a few pairs of this bird 
breeding in July, 1876. 
Furmar Perren (“ Molliemoke”), Procellaria glaciilda —On 
the 12th June, 1875, in lat. 52° 28’, I caught a Fulmar with a line 
and hook baited with a piece of fat. These birds are often so 
caught by sailors; they invariably get sea-sick when they are 
placed on deck, from which they are unable to raise themselves 
by flight. This specimen was much infested with small mallo- 
phagous ticks. From this point northwards, Fulmars were 
frequent and often abundant about the ship, especially upon 
floating ice in Baffin’s Bay, and as far north as Cape York, 
lat. 76°. Afterwards they decreased in numbers up to Cape 
Sabine, in lat. 78° 45’. The first Fulmars which I observed on 
our homeward journey were seen upon the 11th September, 1876, 
in the neighbourhood of Whale Sound, in lat. 77° 10’. 
Arctic SHEARWATER, Pufinus major.—Small flocks of this 
bird appeared about the ship on the 16th June, 1875, in 
lat. 52° 23’; after that they were frequently observed until the 
26th June, when I saw them for the last time in lat. 58°, about a 
hundred miles south of Cape Farewell. 
Srormy Perret, Procellaria pelagica.—From the 5th to the 
23rd June, lat. 53° to 59°, these birds were generally to be seen 
skimming the water in the neighbourhood of the ship. A little 
south of Cape Farewell, and a couple of degrees to the eastward, 
J lost sight of them until the lst July, when I saw two Stormy 
Petrels off Godhaab, on the coast of Greenland, in lat. 64°. The 
occurrence of this bird in the Greenland seas has been disputed.
