Birds of Celebes: Falconidae. 
(Lotta, . Minahassa, 23._ June 1894: Nat. Coll. - C 12237). An adult (f (Macassar, 
Wallace in the British Museum) has the bars present on the basal half of the 
wings, hut much obliterated; tail, not barred, above blackish slate, below shining 
dusky; under surface of body deep cinnamon -chestnut. This description appears to 
apply to another specimen — from the bars being perceptible on its tail apparently 
a female shot at Lotta N. Celebes 29. May 1893 by our native collectors, now in 
the Tring Museum. 
Young. Above resembling the adult; below the dark cinnamon-ground colour is plentifully 
marked with streaks and spots of black, which take the form of sagittate marks and 
bars on the under wing-coverts; the bars on wings and tail below more distinct than 
in adults from the same locality (Java, C 10553, S. E. New auinea. Nr. 8726). 
A young specimen from Celebes (Tweedd. Coll, in Brit. Mus.) does not corres- 
pond as regards the tail with the above adult (T from Macassar, having it barred 
with cinnamon as in a young one from Sikkim.

The range of F. sevenis aiopears to be checked and bounded by the oc- 
currence of two rival species of Hobby, the Palaearctic F. suhhuteo L. on the 
one hand, and the Australasian F. hmulatus Lath, on the other. The ranges 
of both of these species overlap that of F. severus, and that of F. lunulatus, in 
particular, encroaches far into it; F. severus and F. suhhuteo are found together 
in India, where the former, according to Colonel Bad cliff e “is local, while 
F, suhhuteo is migratory”; and, to the south, both F. severus and F. hmulatus 
have been obtained in New Britain (d 9) and also in Ceram and Ternate. 
Whether F. severus is a migratory species in the East Indian Archipelago, 
there is no sufficient evidence to show; probably it is not such. In the cold 
season, however, as was noted by Blyth, “it visits the plains of Bengal, where 
it is somewhat rare”; in Ceylon it can only be regarded as a straggler according 
to Colonel Legge, who believes that it finds its way to that island during the 
season of migration. There is no evidence of a similar movement in the East
