186 LIST OF BIRDS OF BORNEO. 
GENUS—FALCO. 
429.—Falco communis. 
Falco communis, Salvad., Ucc. Bor., p. 1. 
E. peregrimus, Sharpe, P. Z. S., 1876, p. 3237 Vda 
1669; p-, 195- 
Labuan (Treacher) ; Lawas (Pretyman) ; Abai (White- 
head); Kina Balu Mt. at 8,000 ft. (Whitehead) ; 
Sandakan (W. B. Pryer); Banjarmasin (Mottley) ; 
Taguso, Palawan (Whitehead); Puerto Princesa 
(Platen). 
It is still a matter of doubt whether the Australian F’. 
melanogenys (Gould) ranges as far north as Borneo. 
A very dark and richly-coloured Peregrine from 
Lawas in the British Museum is referred by Mr. 
Gurney (Ibis, 1882, p. 302) to Falco melanogenys. 
On the other hand this specimen with the dark 
birds recorded from Java are believed by Mr. Sharpe 
to be representatives of a local race of Peregrines 
permanently resident in the islands above-mentioned. 
The birds ordinarily met with in Labuan and North- 
ern Borneo appear in the N. E. Monsoon, and are 
doubtless regular winter migrants, probably from 
China. Mr. Whitehead, although he identified a 
Peregrine on Kina Balu, failed to obtain a specimen 
from that locality.
