* I cannot separate A. canadensis, the old birds of which appear to be indi- 

 stinc'ui^hable. The young ones from America wear a peculiarly light plumage 

 on the head and neck, and are of large size, though in this respect they are 

 equalled by Himalayan specimens. Capt. Unwin's female bird, from Huzara, 

 measures :— total length 40 inches, wing 27-9, tail 15, tarsus 4. These measure- 

 ments, which are from the skin, somewhat surpass those of the bu-d wnen mea- 

 sured in the flesh. A North- American specimen measures :— total length 

 41 inches, wing 2G-25, tail 16-5, tarsus 4-1.
