The sub.specific term of Bubo virgivianus magdlanicvs is imlenable 
from Gmeliu* * * § , as usually cited, since it is there merely a varietal name 
under Strix bubo, and consequently without nomenclatnral status. 
Furthermore, it .seems not to have been employed by any other author 
prior to 1817, when the bird was called by Vieillot Strix vacvruhi\ , 
which designation, therefore, mn,st now be revived. 
The name Asio inagcllaniais wapacutku ( Gmeliu)];, u.sed by me§ 
for the preoccupied Strix i^Biibo) arcticaoi Swaiuson^f, should be replaced 
hy Bubo virginia)n(s siibarcticus 'AoyW, as shown by Mr. William Brewster°, 
for Gmelin’s Strix zvapacuthu" , is apparently, after all, based upon 
Nyctea nyctca. 
The New- World forms of Bubo are all, without doubt, subspecies of 
Bzibo virginiauus, and should now .stand as follows :
