Obs. I venture to characterise thisbird as distinctfrom the Pan- 

 dion Haliaetus, as it appears to be ahvays smaller in size, and is 

 moreover said to liave yello\v tarsi. Tlie individual f'roni whicli niy 

 description was taken lias this cliaracter to a certain extent, altliougli 

 a leaden tint pervades in sonie parts. I have never seen a speciuien 

 of" P. Haliaetus Avilli so niuch wliite on tlie liead and back of the 

 neck as is l'ound in the Australian bird.

Obs. I find tlie young of this species much darkei" than the adult, 

 particularly in the markings of the chest and abdomen ; the iipper 

 surface also has most of the feathers tinged with reddish brovvn, 

 and the tail-feathers are tipped with this colour. 



This species is nearly allied to Falco suhbutco and F. jEsalon.
