Bantayan (McGregor); Guimaras (Meyer, Steere Exp.) ; Masbate (Bourns ¢ 
Worcester, MeGregor) ; Negros (Steere, Everett, Steere Exp., Bourns & Worcester, 
Whitehead, Keay); Panay (Steere Exp., Bourns & Worcester); Ticao, (Me- 
Gregor); Verde (McGregor). 
Adult.—Very similar to Jole gularis from which it differs only in 
being slightly larger and in having the throat and breast paler. Ten 
males from Masbate and Ticao yield the following extreme and average 
measurements: Wing, 102 to 111 (107); tail, 86 to 94 (90); exposed 
culmen, 22 to 25 (23); bill from nostril, 15 to 18 (17); tarsus, 19.5 
to 23 (21). Nine females from the same localities measure: Wing, 
98 to 106 (99); tail, 87 to 99 (88) ; exposed culmen, 20.5 to 25 (21); 
bill from nostril, 15 to 17 (16) ; tarsus, 18 to 22 (20). 
“Doctor Steere separates the Jole from Panay, Guimaras, and Negros 
from the Luzon, Samar, Bohol, Cebu, Leyte, and Mindanao birds. He 
states that I. gwimarasensis has the ‘size and general coloring of J. rufi- 
gularis, with the light shaft-streaks of J. philippinensis.’ The latter 
differences would not seem to be of special value in differentiating it 
from I. philippinensis and we can find nothing in the size or color of 
our large series of specimens from the central Philippines to warrant us 
in separating them from typical I. philippinensis [=gularis]. 
“Steere mentions the very. different note of the Cebu birds. We were 
unable to perceive the slightest difference in the notes of the birds in 
question and incline to the opinion that the Doctor must have heard the 
note of I. monticola when he crossed over into Cebu.” (Bourns and 
Worcester. )

Porter) ; Semirara (Worcester). 
Adult.—Very much like Jole gularis, but chin and throat light drab- 
brown ; whitish shaft-streaks less conspicuous than in either J. gularis or 
I. guimarasensis; sides of breast and flanks grayer; under parts with 
fewer streaks of pale yellow. Ten males measure: Wing, 102 to 107

from nostril, 15 to 16.5 (16) ; tarsus, 19 to 20 (19.8). 
“Quite common in Mindoro. Two males average: Length, 222; wing,
