"And the under parts of the last four—what general color are they?"
"From white to buff, with different sized and shaped dark markings. The spots on the Wood Thrush are the roundest and blackest; those on the Veery are the smallest, lightest, and most on the throat; on the Hermit they are longer and run together more like stripes; and those on the Olive-back are most like the Hermit's."

Length about seven inches—the same as the Hermit.
Upper parts an even olive color all over.
Under parts cream-yellowish, whiter on the belly, the throat and breast spotted with black.
A yellowish eye-ring, like the creamy color of the breast.
