 Mo rm o n   glacialis,  Leach.

 To  a superficial observer the Mormon glacialis would appear to present  but little difference from  the common  
 species,  so plentiful during  the breeding-season on many of the rocky coasts  of  our  island;  but on  a comparison  
 of  the two species we feel convinced that our readers will  coincide in  our opinion,  of their being specifically  
 distinct.  Its  larger  size  and more  powerful  bill,  which is of  a uniform  rich orange  colour,  together  
 with  the greater  length  of the fleshy appendages over  the  eyes,  will at once serve to  distinguish  this  species  
 from its  near ally  the Mormon fratercula. 
 The Northern Puffin,  as its name implies,  is almost strictly confined to the ice-bound  regions of  the  arctic  
 circle,  over the whole  of which we have  reason to believe  it  is  distributed,  numerous specimens having been  
 from time  to  time  brought home from  Spitzbergen and Kamtschatka  by our navigators  on  their  return from  
 exploring the boreal regions. 
 It occurs but rarely in  the temperate  latitudes,  hence  both  the coasts  of America and  Europe are only  occasionally  
 visited  by i t ;  the  northern  shores  of Russia, Lapland,  &c.  being  among  the  only places  in  our  
 quarter of the globe where it may be looked for with  certainty. 
 The sexes do not appear to differ in  the colouring o f  their plumage, which may be thus described: 
 Crown of the  head  and occiput light brownish grey  tinged  with lilac ;  collar surrounding the neck,  all the  
 upper surface, wings, and tail brownish black tinged with blue;  primaries blackish brown very slightly margined  
 with  paler brown;  sides of the face and  all the under surface white;  bill bright orange red;  corrugated skin  
 at the angle of  the mouth gamboge yellow;  irides orange red ;  irides and  horny appendages grey;  legs  and  
 feet orange with  the webs paler and the claws yellowish brown. 
 We have  figured  an adult of the natural size.
