"Habitat, James Island, Galapagos Archipelago, [October). 



"I am indebted to Mr. G. II. Gray for the descrii)ti()n of this species, 

 which is deposited in the British Museum. Only one specimen was 

 obtained during our visit to the Gahipagos Archipelago ; and this formed 

 part of the collection made by the direction of Captain FitzRoy. 



"This owl is in every respect a true Stri.v; it is fully a third less 

 than the common species of Europe, and differs from it in many respects, 

 especially in the darker colouring of its plumage. The colouring of 

 the Plate is not perfectly accurate in its minuter details." (Darwin.) 



Neither Mr. Townsend nor Messrs. Baur and Adams met with this 

 species on any of the islands.
