This is the original series on the basis of which this race was first 
described. As stated in the description, it agrees with the nominate 
form above and with tuipara of the south bank of the Lower Amazon 
below. It has the chin spot orange (not brownish as in the nominate 
form) but has practically no frontal band, and what little there is is 
not orange (as in twipara) but brownish, almost as in chrysopterus. 
It is known only from the Upper Rio Negro (Santa Isabel, and at the 
mouth of the Rio Cauabury).
