I have been unable to define the specific characters for this owl, as 

 we have on hand none of the other species except O. longicornis, with 

 which of course this has nothing to do. Dr. Eichmond, who examined 

 specimens, writes: "Apparently new. Does not belong to the lempigi 

 group, but more inclined to the menadensis style of coloration." This 

 bird is abundant on Cuyo and is known as "bu-cao." The female type 

 was flushed from the end of a hollow horizontal limb where she probably 

 had a nest with eggs, as the ovary contained one egg soon to be deposited. 

 I greatly regretted that we had to leave Cuyo the next day and were 

 thus unable to get the eggs.
