 the latter less extended toward the naU; size averaging smaller, bill somewhat heavier 

 and wholly black" (Chapman, I.e.). 



^Asio galapagoensis aequatorialis Chubb — "Allied to A. g. galapagoensis 

 (Gould) but larger and dull black above with pale fulvous and white markings to the 

 feathers instead of brown with sandy rufous markings; buff color of under parts paler 

 and dark shaft lines more restricted; wing, 3.22; tail, 1.53 mm.
