Ash-coloured Falcon, Montagu, Ornith. Dict.—Jd. Suppl. 
The British Fauna is indebted to the persevering researches 
and acute discrimination of our countryman Monracvu for 
the discovery of this new species of falcon, the description of 
which he has most accurately given in the Supplement + to 
the work I am so often proud to quote. The resemblance it 
bears to the Hen Harrier was without doubt the cause of its 
remaining so long unnoticed as a separate species, having in 
all probability, when previously met with, been considered 
only as a variety of that bird.
