Remark. I venture to characterise this bird as distinct from the Pandion Halice'etus, as it appears to 
be always smaller in size, and is moreover said to have yellow tarsi. The individual from which my 
description was taken has this character to a certain extent, although a leaden tint pervades in some 
parts. I have never seen a specimen of P. Haliceetus with so much white on the head and back of 
the neck as is found in the Australian bird. 
Habitat. Australia.
