Turning to the range of the species in Greenland itself, we find 
that of the 62 stragglers only 9 are known to have penetrated to 
North Greenland, while the localities whence 13 were procured 
are not named. Supposing that the same proportion of northern 
stragglers exists among the 13 of which no particulars have been 
given as among the 49 of which we know the locality, the number 
of stragglers to North Greenland may be raised to 12, all of which 
may reasonably be supposed to have passed through the limits of 
South Greenland. Fonr-fifths of the stragglers named in this list 
may accordingly be safely dismissed from our mind, when con- 
sidering even the casual visitors to that part of Greenland which 
lies nearest to the scene of the new Expedition’s labours. The 
remainder are not Arctic birds in any sense, since they have not 
crossed the Polar Circle, and indeed many of them have hardly 
been within 400 miles of it. 
Then of the regular denizens, which, taking the highest estimate, 
cannot be put at more than 63, we find that 16—or nearly one- 
fourth—do not occur within the Polar Circle, and are therefore not 
entitled to the name of Arctic birds. The remaining 47 are recorded 
as inhabiting North Greenland, but their northward extension is 
uncertain. Considering, however, what is known of them in other
