SUMMARY OF CHANGES. 387 



Glauddium phalaenoides (Daudin), 1800, becomes G. hradlianvm ridgivayi 

 Sharpe, 1875. 

 The race phalaenoides has been restricted to southern Mexico and the 

 northern form named ridgwayi; while both are now regarded as subspecies 

 of the South American brasib'anum Gmehn, 1788. (Cf. Ridgway, Bull. 

 U. S. Nat. Mus., No. 50, Pt. VI, April 8, 1914, 798.) (p. 168) 



Strix varia albogilva Bangs, 1908, becomes S. varia helveola Bangs, 1899. 



The former name was proposed under the assumption that helveola was 

 invalidated by an earlier helvola but this view is not sustained and the 

 original name is restored, (p. 170) 



Scotiaptex nebulosa lapponica (Thunberg), 1798, becomes S. n. harhata (La- 

 tham), 1790. 

 The birds of eastern Siberia and Alaska are found to differ from those of 

 northern Europe and are separated under the name barbata. (Cf. Ridg- 

 way, Bull. U. S. Nat. Mus., No. 50, Pt. VI, April 8, 1914, 635.) (p. 170) 



Cryptoglaux acadica scotaea (Osgood), 1901, becomes C. a. brooksi Fleming, 

 1916. 

 The type of scotaea proves not to belong to the race resident on the Queen 

 Charlotte Islands but is a stray from the mainland referable to acadica 

 and the island race must be known as brooksi. (Cf . Ridgway, Bull. U. S. 

 Nat. Mus., No. 50, Pt. VI, April 8, 1914, 629.) (p. 172) 



Antrostomus vodferus macromystax (Wagler), 1831, becomes A. v. arizonae 

 Brewster, 1881. 

 A. c. macromystax is now restricted to southern Mexico and the northern 

 form separated under Brewster's name. (Cf. Oberholser, Bull. U. S. 

 Nat. Mus., No. 86, April 6, 1914, 12.) (p. 174) 



Chordeiles virginianus virginianus (Gmelin), 1789, becomes C. minor minor 

 (Forster), 1771. 

 The latter name is found to be based on exactly the same references as 

 virginianus and has many years priority; all subspecies of virginianus 

 become subspecies of minor. (Cf. Richmond, Auk, XXXIV, 1917, 88.) 

 (p. 175) 



Cypseloides has been divided and C. niger borealis referred to Nephoecetes. 

 (p. 177) 



Aeronautes melanoleucus (Baird), 1854, becomes A. saxatalis saxatalis (Wood- 

 house), 1853. 

 Woodhouse described the bird from life but as he did not secure a specimen 

 and as the description was somewhat inaccurate his name has hitherto 

 been rejected. It is now accepted and a trinomial form adopted as there 

 is another race in Central America. (Cf. Oberholser, Auk, XXXVII, 

 1920, 294.) (p. 179) 



Cyanolaemus has been combined with Lampornis. (p. 182)
