•more distinct on the breast and belly, and extend F. f>aium- 

 to the vent- feathers and under-coverts of the tail. 

 The feathers on the thighs are like the ground- i 

 colour of the breast, and are marked on the centre 

 with narrow arrow-shaped lines pointing upwards. 

 The tail extends five or six inches beyond the ex- 

 tremity of the wings, and is alternately barred 

 with black and ash-colour, the tip is nearly white ; 

 legs yellow ; claws black. 



This will be found to approximate so nearly to 

 some of the descriptions which have been given 

 of the Gentle Falcon, as perfectly to warrant the 

 conclusion which has been drawn, that many 

 birds described under that name, are the young 

 of the Goshawk. 



The next species whose history requires to be commu- 

 considered, is the Common Falcon *. 



* When I had the honour of presenting this paper to the 

 Society, I was not aware that several of the observations which 

 it contains had been anticipated in the work of a foreign na- 

 turalist, with whose writings I was at that time unacquainted. 

 The publication to which I allude, is the Gemeiniiizige nature 

 geschichte Deutcklands, von J. M Beckstein. It does not 

 appear to have been much consulted by the ornithologists of 

 this country, nor are the remarks which it contains, in as far as 

 I have had an opportunity of judging, familiar to the French 

 writers. Through the kindness of Professor Jameson, I have 

 recently been enabled to compare the remarks of Beckstein
