BUTORIDES JAVANICA (Horsf.). 
This common species was noted in Sibuyan and a specimen was 
killed in Romblon. 
PYRRHERODIAS MANILLENSIS (Meyen). 
One specimen from Romblon. 
ARDETTA CINNAMOMEA (Gm.). 
One specimen taken in Sibuyan. 
DenprocyeNA ARcuATA (Horsf.). 
A few tree ducks were to be found along the river in Sibuyan, 
where three specimens were killed. This is the only duck so far 
known from Romblon Province; another species of duck, probably 
Anas luzonica, was said to visit Sibuyan, but it was not observed 
by us.

from a specimen of S. holospilus from Tarlac Province, Luzon, 
which is larger, darker below, and has fewer white spots on the 
breast. The throat of the Luzon bird is brown, while in 8. 
panayensis this region is gray.

Romblon and Sibuyan. 
HALIASTUR INTERMEDIUS Gurney. 
Observed in Sibuyan. 
PERNIS PTILORHYNCHUS (Temm.).

A live kite, brought to our house in Sibuyan, is the only specimen 
of this species known from Romblon Province. 
FALCO PEREGRINUS Tunst. 
One specimen of the duck hawk from Sibuyan. 
Ninox spiLonotus Bourns and Worcester. 
In color pattern this is remarkably similar to N. mindorensis 
but is considerably darker and more rusty on the lower parts. In 
our specimen, a male from Sibuyan, the white patches on scapulars, 
conspicuous in other species of Ninow, are reduced to bars of pale
