latitudes; the latter, apparently, does not occur at all in Green- 
land. 
Lirrte Avx (‘ Rotch”), Mergulus alle-—A few Rotches were 
found breeding in Svarte Vogel Bay on July 16th, 1875. On the 
25th they were very abundant at Cape York, lat. 76°, breeding 
amongst loose detritus at the base of high cliffs. Here the 
Esquimaux build little piles of stones in which these birds are 
induced to lay their eggs; these structures, and quantities of the 
birds’ bones strewn about, gave evidence of the nature of these 
* Arctic Highlanders’”’ food, who were then chiefly away hunting. 
At this date the young birds were just leaving their nests for the 
water. On the 28th July, myriads of Little Auks were congregated 
about their chief breeding-place at Port Foulke. They were not 
in the least alarmed by visitors, and their incessant chattering as 
we scrambled down amongst them was deafening. ‘They fly in 
such close bands as to obstruct the light at times, and settle 
down in such compact masses that, unless seen to alight, it 
would be impossible, even at a short gunshot range, to dis- 
tinguish the crowd of birds from the rock on which they have 
settled. Foulke Fiord, lat. 78° 18’, is probably their most 
northern breeding-place. In 1876 I saw a few Little Auks on 
the lst September at Cape Hawke, in lat. 79° 30’. The flesh 
of these birds was highly esteemed when made into a pie for the 
ward-room mess. 
Razorpityi, Alcea torda.— A few pairs were breeding in 
Svarte Vogel Bay in July, 1875, when I obtained a couple of 
eggs. I met with no Razorbills north of this point. 
Cormorant, Phalacrocorax carbo.—I gathered a few eggs of 
the Cormorant with those of the last species, in lat. 69° 42’. 
There were from twenty to thirty pairs breeding at the cliffs near 
to the ridge overlooking the Itifdliarsuk Glacier. 
Lone-TatteD Duck, Harelda glacialis.—At Disco, lat. 69° 14’, 
a couple of pairs of this species were breeding by Blase Dalen 
Lake in the beginning of July, 1875. The parent birds were 
obtained, but I was unable to discover their nests. These ducks 
were very wary and, upon my first visit to the lake, would admit 
of no approach, keeping upon a central floating sheet of ice which 
was inaccessible, or flying out of range. ‘Two days afterwards, 
however, I planned an expedition against them, and, having 
earried a ‘‘collapsable” boat to the spot, we shot them all. On
