360 TTi^elJtk Sup fitment to the A. O. U. Check-List. ^^"^ 



Olor VS. Cygnus {cf. Elliot, 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. 



298c. Canachites canadensis canace vs. C, canadensis, and 



'298i. Canachites canadensis osgoodi vs. C. canadensis {cf. 

 Grant, Ibis, 1902, 233, 234). No change is considered 

 necessary. 



820. Columbigallina passerina terrestris vs. Chajncrpelia 

 passerina, and 



320a. Columbigallina passerina pallescens vs. Chamapelia 

 passerina {if. Godman, Biol. Centr.-Am., Aves, HI, 1902, 



250)- 

 The Committee finds no reason for altering the status of these 

 subspecies in the Check-List. ^ 



Buteola {Cf Coues, Osprey, III, 1899, 144). The characters 

 are too slight to warrant the adoption of Buteola as a full 

 genus. 



Strix vs. A/uco., and Strigidae vs. AJuconidce {cf Coues, Auk, 

 1900, 66). No change is deemed necessary. Dr. Coues 

 was in error when he stated that Brisson fixed the type of 

 the genus Strix in 1760. {Cf. Stone, Auk, XX, 272.) 



394J. Dryobates pubescens homorus vs. D. p. leiicurus {cf. 

 W. K. Fisher, Condor, IV, 1902, 69). It is considered 

 inexpedient to make a change here, as Hartlaul^'s description 

 of D. Icncurus is too brief and inaccurate to render identi- 

 fication a matter of certainty. 



Antrostomus vs. Caprimulgus {cf. Tenth Suppl., .Auk, 1901, 

 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. E. difficilis {cf. 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.
