Mr. R. Ridgway on the Genus Glaucidium. 15 



the pattern of the tail-markings are hard to reconcile with a 

 belief in their identity, especially in view of the great con- 

 stancy of this feature in the two phases of G. ferrugineum. 



Had I been able to comijare the two forms side by side, I 

 should probably have been induced to hint at the possibility

The above synonymy will at once indicate that while I 

 agree with Mr. Sharpe in considering my G. ferrugineum and 

 G. infuscatum to be the same species, I differ from him re-

 in reference to the number of names included among its
