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 compare the two forms side by side, I 
should probably have been induced to hint at the possibility 
of their identity ; but the only specimens of G. /ansbergi seen 
at the time my descriptions were prepared, were in a collec- 
tion which contained no example of G. jardinii.

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- 
garding the name to be used to designate the species, and also 
in reference to the number of names included among its
