 Author is induced to take a short notice of it, and the more 

 so because it has hitherto been passed over in other histories

 attached to the possession of the bird, and the authorized 

 power to protect it.

 on this subject. Some interesting details published in 'The AthcnKum,' 18th 

 August, 1877, are reproduced in ' The Zoologist ' of the same year (p. 445).
