* I cannot myself separate the Barn-Owls of Tenerife from the 

 Mediterranean form T. alba alba. Two specimens have been examined 

 in the British Museum collection (Meade-Waldo coll.). Dr. Hartert 

 writes me under date 10,'1/19 : " In Cabrera's collection in Laguna, 

 I saw, in 1901, several Tytn (Flammea) with white undersides, which 

 without any material for comparison appeared to me to be the 

 Mediterranean form."
