* B. melanotis is the species wliieh has the crown orange-rufous, whereby it 

 ought, strictly speaking, to be placed in section c'" ; but it is cleurlv onlv a race 

 of B. auricularis. All the birds included under section d'" might well be 

 ranked as subspecies, but the differences, though slight, are constant, and I give 

 them full specific rauk until intermediate links are found to connect them more 

 closely together.
