IOLE. 509 



Bantayan (McGregor) ; Guimaras (Meyer, Steere Exp.) ; Masbate (Bourns & 

 Worcester, McGregor) ; Negros (Steere, Everett, Steere Exp., Bourns & Worcester, 

 Whitehcad, Keay) ; Panay (Stccrc Exp., Bourns & Worcester] ; Ticao, (Mc- 

 Gregor) ; Verde (McGregor). 



Adult. Very similar to lole 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). Xine 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 lole from Panay, Guimaras, and Negros 

 from the Luzon, Samar, Bohol, Cebu, Leyte, and Mindanao birds. He 

 states that /. guimarasensis has the 'size and general coloring of I. rufi- 

 gularis, with the light shaft-streaks of /. 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 /. 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.)
