tween the avifauna of the Caqueté and Napo regions leave little doubt that 
our series of ten specimens from La Murelia and Florencia should be referred 
to L. r. dubusi. It-is true that after an examination of Bonaparte’s type 
Salvadori (Cat. B. M., XXI, p. 552) refers it to L. rufaxilla but this conclu- 
sion is obviously due to the lack of proper material, the series at my com- 
mand showing beyond question, that the form from the western margin of 
Amazonia is quite unlike the Guiana bird.

Asio flammeus bogotensis subsp. nov. 
Char. subsp.— Similar to A. f. fammeus but ochraceous markings above much 
more restricted or, in places, obsolete, the upperparts, therefore, much darker ; tarsi 
and toes less heavily feathered, the feathered area on the latter less extended toward 
the nail; size averaging smaller; bill somewhat heavier and wholly black.
