324 NORTHERN ZOOLOGY. 



chin ; the upper half of the throat is covered by scale-like feathers of a brilliant and change- 

 able ruby-red colour, the feathers round which, towards the breast and on the sides of the 

 neck, are white, which becomes more obscure on the body, vent, and under tail covers : the 

 sides are dusky, but glossed with green. 



Fokm. — Bill perfectly straight in its entire length. Wimjs short ; the quills narrow, and 

 not reaching to the end of the tail ; the fifth, sixth, seventh, and eighth quills are very deeply 

 and obliquely notched at the tip of their outer webs, in such a marked and peculiar manner, 

 as to give an idea that the notch was artificial. The tail is rather short, but distinctly forked ; 

 the two outer feathers are nearly equal, the rest gradually diminish : they have an obtusely 

 pointed form, being narrowed towards their ends ; but those in the middle are broader.

The discovery of this superb species, in the cold and inhospitable regions of 

 Nootka Sound, is due to our great navigator, Captain Cook; while to Dr. Latham 

 belongs the honour of first making it known to science. By a singular chance, 

 we have at this moment before us one of the identical specimens, in perfect 

 preservation, collected by the naturalists of that expedition : it was pre- 

 sented by the late Sir Joseph Banks to Mr. Bullock, and was purchased by us, 

 at a very high price, at the dispersion of that collector's museum by public 

 auction. We are likewise able to vouch for its geographic range, to the south-
