nostrils in front, and passing under and beyond the termination of 

 them at the sides, but seldom reaching the corner of the mouth, 

 except in vety old individuals, in which this mark extends under 

 and behind the nostrils, crosses the base of the bill next the fore- 

 head, leaving only the central part of the bill (between the nostrils) 

 and the nail black ; which latter part is sometimes, though rarely, 

 white ; legs and feet, reddish orange ; wings, when closed, reaching 

 2 inches beyond the tail. The young of this species are darker, 

 and the markings less distinct ; the bill is shorter, the mark upon it 

 narrower, and of a deep red colour; the legs and feet, pale orange. 



*' Anser cinereus, Meyer. Grey Lag Goose. Entire length, 35

 The plumage more cinereous than in the last-described species ; the 

 shoulders and rump, light grey ; breast and belly, white, sometimes 

 spotted with black ; the bill, 21 inches long ; more robust, deeper,

 Goose, and of a dull yellow, inclining to flesh colour towards the 

 nail, which is white ; in summer the bill assumes a redder tint ; legs 

 and feet, pale flesh colour ; wings, when closed, even with the end 

 of the tail. The 3'^oung of this species are darker than the adults, 

 but the grey upon the shoulders and rump, the form of the bill, and

 young of any of the other species.
