S. m. gouldii replaces S. m. maculirostris in Lower Amazonia. Its chief 
character consists of the large, continuous black patch occupying more than the 
basal half of the upper mandible, while in the South Brazilian race there are several 
distinctly separated transverse blotches in its stead.]

This bird answers well to the MS. description drawn up from the typical 
examples which had been forwarded for my inspection some years ago. P. c. obscura 
resembles, on the lower parts, the well-known P. ¢. cayana, of Cayenne, Guiana, 
Orinoco region, etc., but the upper surface is much daller, more walnnt-brown, less 
chestnut. Specimens from the Rio Jurud* belong likewise to this form, which 
wonld appear to range over a considerable portion of Central Amazonia, though the 
exact limits of its area are not yet known. 
Notwithstanding Mr. Stone’s contention,+ I am unwilling to unite P. ¢. cabanisi 
Allen, from Mattogrosso, to P. c. pallescens Cab. & Heine, for birds from 
Chapada are much larger than a series from Minas and Bahia which I believe 
to represent pallescens.
