Characters . — Similar to Ixobrychus sinensis bryani (Seale) from Guam 
but smaller, bill in adult more slender, back darker, more brownish, under 
tail coverts somewhat more buffy, upper breast and foreneck slightly paler, 
back of neck slightly paler, more reddish. 
The type is a specimen from Paete, Laguna Province, Luzon, 
collected by McGregor and Celestino. 
Ixobrychus cinnamomea (Gmelin) . 
One specimen of the cinnamon bittern was collected near 
Culasi. 
Dendrocygna arcuata (Horsfield) . 
Specimens of this tree duck were collected near Culasi on May 
28 and on June 2. 
Anas luzonica Fraser. 
About the middle of May there were a few mallards in the 
marsh at Culasi, and pairs were found later at various places 
in the vicinity of that town. 
Fregata aquila (Linnaeus) ? 
On June 30 after four days of wind and rain a man-of-war 
bird was seen flying over Batbatan Island. On July 11 three 
more man-of-war birds were seen at Panganta, about 3 kilo- 
meters north of Culasi, and the next day a solitary bird of this 
species was seen over the beach at Sebaste. For seven days 
preceding July 11 there was heavy wind and much rain. Man- 
of-war birds may be expected to appear near the shore of any 
of the islands after a heavy wind. This genus has not been 
previously recorded from Panay. As we could not collect a 
specimen the species seen is in doubt. 
Spilomis panay ensis Steere. 
One female of the Panay serpent eagle was collected at Cu- 
lasi, and a young female was collected at Flores. 
Haliastur intermedius Gurney. 
A hawk of this common species, which was abundant at Tibiao 
and at Culasi, attempted to catch some small chickens, but at the 
noisy warning of two hens the chickens ran to the protection of a 
bamboo thicket. On another occasion one of these hawks suc- 
ceeded in taking a small fish that a fisherman had left on the 
beach a short distance behind him. 
Elanus hypoleucus Gould. 
One specimen, a male, of this kite was collected at Culasi ; the 
species has not been previously recorded from Panay.
