PUFFINS. 
Logan, brought to Orkney by one of the whalers, 
from Davis Straits, lias the body pure white, except 
the mantle and lower parts of the back and wings, 
which are brownish grey, tinted with bluish ; the 
base of the covers and tertials are paler, showing a 
shaded broad band across ; the tail is slightly 
greyish at the tip, and the under-covers exceed it 
in length ; the bill is described to be gamboge- 
yellow, the legs and feet yellowish grey, but in 
the dried skins the colours have completely faded. 
Another specimen, from the same locality, has the 
whole plumage of a brownish grey, paler beneath, 
darker on the wings, and with the quills and a 
spot on the anterior angle of the eye, dark blackish 
grey ; feet, legs, and bill, are here also of a darker 
shade. 
The Puffins , or Sheerwater Petrels, have been 
separated from the strong-built Fulmar on account 
of their rather more slender shape, their more slen- 
der bill, the structure of the nostrils, and the back- 
ward position of the legs. We believe the species 
will prove numerous, though comparatively few are 
at present known, and some of the lesser run much 
into the larger forms of the next genus. 
Genus Puffinus, Brisson. — Gene ric characters . — 
Bill of middle length, straight, slender, maxilla 
arched and hooked at the tip ; that of the man- 
dible bent downwards, and fitting into the 
other without any angle at the symphisis ;
