Strix tenebricosa Ar/aki. 



This bird is, in New-Guinea, the representant of Strix 

 tenebricosa, Gould, from South-Eastern Australia. Closely- 

 resembling the latter, it differs however by its smaller 

 size , by the white spots of the feathers being larger and 

 more regular orbicular , and by the light sooty brown color 

 of the face strongly inclining to white. 



The measures (in French measure) of the principal parts 

 are as follow — 



In Strix tenebricosa Arfaki : wing 9 inches 1 line ; point 

 of wing 1 inch 10 lines; tail 4 inches 4 lines; tarse 30 

 lines; middle toe (without nail) 18 lines. 



In five specimens of Strix tenebricosa from Australia: 

 wing 10^/, to 11 Va inches; point of wing 18 to 27 lines; 

 tail 5 to 5^/2 inches; tarse 32 lines; middle toe Vl„ to 

 2 inches. 



A single specimen of this conspecies was sent to the 

 Leyden Museum by one of the Dutch Missionaries of Andaï 

 It was killed near Hattam , on the G^'^ of December 1875.
