BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 413
Uruguay, are distinctly intermediate, as they show a tendency toward
a narrower median crown stripe and darker, more rufescent
dorsal surface. They may, however, be placed without difficulty
with argentina. Specimens that I have examined from INIontevideo
are similar to argentina from northern Buenos Aires, while one from
Quinta, a few miles from the town of Rio Grande do Sul, Brazil
(collected by E. G. Holt), is representative of capensis. The skins
from San Vi»^ente thus are connecting intermediates between the two
forms.
In the following table are given pertinent measurements, in millimeters,
of the series taken of the present form.
