NORTHERN ZOOLOGY. 



animal substances thrown up by the sea, and also on the matters which the Gulls 

 disgorge when pursued by it. It retires from the north in the winter, and makes 

 its first appearance at Hudson's Bay in May, coming in from seaward. The 

 Indians abhor it, considering it to be a companion of the Esquimaux, and to 

 partake of their evil qualities. 



DESCRIPTION 



Of a male, killed in the Welcome, lat. 66°, in June. 



Colour. — Head, neck, under eyelid, a patch at the corner of the mouth, back, wings, and 

 tail, brownish-black ; flanks and sides of the breast blotched with the same. Shafts of the 

 quill and tail feathers white, except at their tips. Neck straw-yellow. Auriculars, chin, 

 throat, breast, and belly, white. Vent and under tail coverts blackish-brown. Bill dark- 

 brown, tipped with black. Legs black. 



Form. — Plumage of the nape long, tapering, and acute. Tail slightly rounded, inde- 

 pendent of the middle pair of feathers, which project three inches. These latter retain their 

 breadth throughout, are rounded at the tip, and are twisted so that their vanes incline 

 obliquely towards each other. Tarsus covered posteriorly by rough, angular scales, resem- 

 bling those of some pine-cones ; anteriorly, the lower two-thirds are acute, and are covered 

 by strong keeled scales, very different from those of L. parasitica, in which the anterior scales 

 resemble those of a Gull.
