 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.
