each scale ofteu with a central line of lighter. There appears to be no 

 blue on the chin, and that on the flanks is very faintly defined. There 

 is not the slightest trace of a cervical collar, although sometimes a 

 black patch on the shoulder. 



Sometimes the dorsal bands are quite close together, with but little

 legs, are blue, changing to blackish internally, where there is a light 

 interval of about six rows of scales. The color does not reach the groin.

 back are more transverse and continuous over five rows of scales, instead 

 of being each in ten blotches. In high-plumaged males there is a black 

 longitudinal patcli extending from the insertion of the arm to the bare 

 space under the lateral fold, scarcely united to the blackish band
