Similar to T. p. pratincola but much darker, the tawiij phase greatly 

 predominating, having the upper parts much more uniformly mot- 

 tled dusky grayish (there being little, if any, ochraceous or tawny 

 admixture), the white specks more Unear, the face more strongly 

 tinged or suffused with dull purplish vinaceous (becoming black in 

 front of eye), facial circle or rim deep orange-ochraceous above and 

 black, or nearly so, below ears, the under parts entirely deep orange- 

 ochraceous or ocliraceous-tawny, w^ith numerous small irregular spots 

 of dusky, which, in part, often assume tlie form of zigzag transverse 

 motthngs; light phase (relatively rare), wliite beneath but upper 

 parts almost wholly mottled dusky grayish.

a The name guatemalse was an inadvertence or possibly a lapsus, since no Guate- 

 malan examples were in hand when the form was described and named, and none have 

 been seen by me since that time. The Guatemalan Barn Owl is probably T. p. 

 pratincola, at least that of the more eastern parts of the country is almost certainly so; 

 but T. p. guatemalse may occur on the Pacific side, since specimens of the latter from 

 Salvador were examined by me at the time the form was described; indeed, the 

 remarks concerning Guatemalan specimens in the Biologia Central i- Americana (Aves, 

 iii, 3) indicate that some, at least, Guatemalan specimens are referable to this form. 

 b Three specimens. c Two specimens.
