^Hypnelus ruficollis coloratus Ridgway: Differs from H. r. ruficollis in having 

 the under parts of body deep buff; throat decidedly darker, followed by a narrow 

 band of buffy white (much narrower than in H. r. ruficollis); black pectoral band 

 broader; pale spots on scapulars, etc. smaller. This is a strongly marked form which 

 may prove worthy of specific rank.
