THE LARGE-BILLED PUFFIN. 
Mormon glacialis, Leach. 
PLATE COGOLXin.— Male. 
Although my learned friend Prince Charles Bonaparte says in his 
Synopsis of the Birds of the United States, that this species is not uncom- 
mon in winter on our coast, I have only once met with it, and even then I 
rather supposed than was actually certain that the birds observed were 
Large-billed Puffins. They occurred on the outer side of the Island of 
Grand Manan, at the entrance of the Bay of Fundy. None were seen by 
myself or my companions on our way to Labrador, or in that country, so 
that I am unable to say anything respecting the habits of this remarkable 
bird. The specimens from which my figures were taken were kindly lent 
to me by Mr. Gould of London, whose name must be familiar to you as a 
successful cultivator of Ornithology.

Male, 13, 24*. 
Very rare, and in winter only, off the Bay of Fundy. 
Adult Male. 
Bill about the length of the head, nearly as high as long, exceedingly 
compressed, at the base higher than the head, obliquely furrowed on the 
sides. Upper mandible with a horny rim along the incurved basal margin, 
its dorsal line irregularly curved from the base, the ridge very narrow but 
rounded, the sides rapidly sloping, and marked with three curved oblique 
grooves, the edges strong, rather sharp, their outline nearly straight, the tip 
deflected, very narrow, but obtuse. Between the basal rim and the first 
groove is a triangular flat space, in the lower part of which, close to the edge 
of the mandible, is the linear direct nostril. Lower mandible with the 
angle narrow, and so placed that the base is inflected much beyond the 
perpendicular, the dorsal line irregularly curved, towards the end ascending 
and nearly straight, the ridge narrow, broader about the middle, the sides
