60 BOURNS AND WORCESTER: PRELIMINARY NOTES. 



from Negros and Masbate as well as in those from Panay. The 

 presumptive evidence against finding one species of Orthotomus in 

 Panay and another in Guimaras is of course very strong. Guimaras 

 is to all intents and purposes a part of Panay and there are no 

 other known differences between the birds of the two islands. Mas- 

 bate is a new locality for the species.

 1891, p. 313. 



Dr. Steere separates the lole from Panay, Guimaras and Negros 

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

 He states that I. guimarasensis has the "size and general coloring 

 of I. rufigularis, with the light shaft streaks of I. philippinensis." 



The latter character would not seem to be of especial value in dif- 

 ferentiating 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. philip- 

 pinensis. 



Dr. 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.
