Saltator intermedius Lawr. 
Nineteen specimens, both sexes. 
This is another very well-marked form, occurring in Chiriqui 
and Panama, that has lately not been recognized as distinct. In 
the very large series I have just examined I find no intergrades 
between it and S. magnoides of southern Mexico, Nicaragua and 
Costa Rica; in fact, specimens from the last-named country are 
quite as extreme magnoides as are Mexican examples. The chief 
differences between the two forms are as follows. In S. magnoides 
the black band behind the throat patch is very broad, often 
extending back over the breast; the under parts are dark gray. 
In S. zntermedius the black band behind the throat patch is very 
narrow, often reduced to a series of black spots, and sometimes 
wholly wanting; the under parts are dull brownish (not gray). 
S. intermedius may or may not intergrade with S. magnus of 
northern South America. I have seen no specimens, however, 
that show any tendency to such an intergradation. S. magnus is 
so much smaller and has such a weak bill (in comparison to the 
bill of .S. z/ermedius), besides differing much in color, that, even 
if intergradation does take place, all three must stand as strongly 
characterized forms.

Arremon aurantiirostris Lafr.
