 able to I'liiisiclcr this bird as the southern race of minimum, as the tlitrerenccs — i. e. smaller size 

 and whiter wiiict-liauds — are just what we iind in several other species of the .same region, 

 coin|)ared with allicil and jirohaWy eo-si)ecilie northern types, — as (irisciijularis and acoilicus, 

 southern s,)erimi'ns of Irnilli var. /tiisH/ns in which the wing-bauds are much whiter than in
