28 NEW SPECIES OF FLYCATCHERS—CHERRIE. 
I have two specimens from the southwest coast of Costa Rica (Pozo 
Azul) that do not seem referable to any of the species of which I find 
descriptions, of either the genus Ornithion or Tyrannulus. I say of 
cither genus, because the two genera seem to me very closely allied and 
the birds in hand might probably be referred as reasonably to the one | 
genus as to the other. However, the bill in T.'brunneicapillus (the only 
species which I have to compare with) is heavier, deeper, and not so 
broad at the base. The examples before me have the nostrils placed in 
the middle of a membrane and the rictal bristles only very feebly de- 
veloped; wing rather short, somewhat rounded; tail square. 
Ornithion pusillum subflavum subsp. nov. 
Type: Adult female (No. 5980,* Museo Nacional de Costa Rica, Pozo 
Azul, Costa Rica, May 8, 1891; C. F. Underwood). Above ashy or 
dusky olive-green, cap dusky blackish, loral region, line on upper and 
lower eyelids, malar region, and anterior part of auriculars ashy whit- 
ish; a blackish spot (same color as crown) behind the eye. Wings and 
tail dusky; greater and middle wing-coverts tipped with olive-yellow- 
ish, forming two rather conspicuous bars, secondaries edged externally 
with pale yellowish. Rectrices narrowly tipped with pale yellowish. 
Below, chin and upper throat ashy-whitish, darkening on the lower throat 
and breast into olive and yellowish. Belly and crissum bright prim- 
rose yellow. Under wing-coverts primrose yellow. Inner edges of pri- 
maries and secondaries whitish, with a yellowish shade on tbe latter. 
Length (skin ), 3.66; wing, 1.90; tail, 1.64; exposed culmen, 0.33 
tarsus, 0.58. 
The second example (No. 5979, Museo Nacional de Costa Rica, Pozo 
Azul, Costa Rica, May 9, 1891), is a male in moulting plumage, the 
rectrices just appearing beyond theircoverts. The wing and tail feath- 
ers are more blackish and the plumage as a whole fresher and brighter. 
Museo Nacional, 
San José de Costa Rica, September 2, 1891. 
*No. 124617, U. S. National Museum. This bird comes very close to O. pusillum 
Cab., from Panama, but is much more distinctly yellow underneath, and should, I 
think, be separated as a local race or subspecies.—R. R.
