* Cryptoglaux acadica brooksi Fleming: A dark race supposed to be confined to 

 the Queen Charlotte Islands. It is quite diflFerent from the bird described as scotaea 

 Osgood from that region, and which Ridgway considered inseparable from C. a. 

 acadica (cf. Bull. U. S. Nat. Mus., No. 50, VI, 1914, p. 629, foot note). It would 

 seem likely, however, that the type of scotaea may prove to be a phase of plumage of 

 the Queen Charlotte Island-bird, in which case, brooksi would be antedated by 

 scotaea, and the name of the Island race would stand as Cryptoglaux acadica scotaea 

 (Osgood), N. Am. Fauna, No. 21, 1901, p. 43 (Massett, Queen Charlotte Islands, 

 British Colombia). See also Flemming, 1. c. (crit.) and Swarth, Univ. California 

 Pub. (Zool.), VII, 191 1, p. 65 (Mitkof, I., Alaska).
