3260 Twelfth Supplement to the A. O. U. Check-List. hiv 
Olor vs. Cygnus (ff Etiior, Auk, 1899, 226). In accor- 
dance with its former ruling (Auk, 1899, 129) the Commit- 
tee decided that the change in this case was unnecessary. 
29S8c, Canachites canadensis canace vs. C. canadensis, and 
298d. Canachites canadensis osgoodi vs. C. canadensis (of 
GRANT, Ibis, 1902, 233, 234). No change is considered 
necessary. 
320. Columbigallina passerina terrestris vs. Chamepe/ia 
passerina, and 
s20¢. Columbigallina passerina pallescens vs. Chamepelia 
passerina (cf. GODMAN, Biol. Centr.-Am., Aves, III, 1902, 
250). 
‘The Committee finds no reason for altering the status of these 
subspecies in the Check-List. 
Buteola (C7 Cours, Osprey, III, 1899, 144). The characters 
are too slight to warrant the adoption of Awfeo/a as a full 
genus, 
Strix vs. 4/uco, and Strigidze vs. Aluconide (of. Cours, Auk, 
1900, 66). No change is deemed necessary. Dr. Coues 
was in error when he stated that Brisson fixed the type of 
the genus Stvx in 1760. (Cf Stoner, Auk, XX, 272.) 
3946. Dryobates pubescens homorus vs. 2). p. eucurus (of. 
W. K. Fisher, Condor, IV, 1902, 69). It is considered 
inexpedient to make a change here, as Hartlaub’s description 
of D. Zeucurus is too brief and inaccurate to render identi- 
fication a matter of certainty. 
Antrostomus vs. Caprimuleus (cf Tenth Suppl. Auk, rgot, 
317). In the absence of precise anatomical information con- 
cerning the members of these genera, it is thought to be 
unwise to change the status of the species in the Check-List. 
464.2. Empidonax insulicola vs. &. dfficilis (of GRINNELL, 
Pac. Coast Avif., No. 3, 1902, 43). No argument is advanced 
for this proposed change, and no action by the Committee is 
deemed necessary.
