1 Scotiaptex Swatns., Classif. B. ii. 1837, 217. Type, Strix cinerea GEL. 
Norz.—The substitution of Ulula Cuv. for Scotiaptex Swarns. as the name for this genus was an errcr. 
Strix uralensis Paut., the type of Ulula, I am now convinced, from recent very careful examination and com- 
parison with both S. cinera and Strix stridula Linn, (the latter being the type of the genus Syrnium Savien.), 
is much more nearly related, structurally and otherwise, to the latter,—so much so, in fact, that Ulula can rank 
at most only as a subgenus of Syrnium.
