place. It has a wide distribution in the islands southeast of the 
Philippines. It probably occurs in all of the larger islands of 
the eastern Philippine group, since specimens have been taken 
in Mindanao, Negros, Luzon, and Polillo. It is very probably 
absent from the Sulu and the Palawan groups. The specimens 
vary greatly in color and markings. The regular folds on the 
back and the dark lores make the form easily recognizable.
