!N^ot being able to distinguish the points in which Dr. Tacza- 

 nowski's G. peruviana differed materially from G. aiiricularis, Salv., 

 I compared his type with that of Mr. Salvin's species, and have 

 come to the conclusion that both are identical. It is true that the 

 latter is a little smaller (wing 2"25 inches, tarsus 0'85), but that 

 is all ; and this difference may be due to the fact that the skin of 

 G. auricularis is indifferently prepared, whereas that of G. peruviana 

 is a fine specimen in full pliimage. The preparation of the skins will 

 also account for the difference in the extent of the black in the 

 region of the eye, which is unduly extended on the base of the ear- 

 coverts in the skin of G. auricularis.
