ON THE DISTRIBUTION OF BARN-OWLS. 



EXPLANATION OF THE MAPS. 



Map I. shows the range of the different races of Strix flammea (yellow). 

 The parts coloured lighter are intended to indicate the probable 

 or occasional range of the species. 



Map II. shows the ranges of Strix nova hollandice (yellow) and Strix tenehricosa 

 (blue), which coalesce in Queensland, Strix castanops (red) 

 being confined to Tasmania. 



Map III. shows the range of the Grass- Owls — Strix Candida (red), Strix 

 capensis (yellow), and Strix thomensis (blue). The probable 

 range of the two former is coloured lighter.
