would run out from the shelter of bushes with tail erect and wings
drooped to watch me curiously.
The song of this sj^ecies is loud, and, though simple in its nature,.
was rather pleasing in contrast to the harsh surroundings among
which it was heard. It may be represented by the syllables took took
took took took^ repeated rapidly. In running Teledromas takes
very long steps. In a series of tracks that I measured I found the
steps to average 150 mm. apart, a remarkable distance when it is
considered that the length of the bird from bill to tail is less than
175 mm.
On the evening of November 25, while setting a line of mousetraps
along a small barranca, I flushed a female from the entrance
of a nest tunnel, an opening near the top of perpendicular cut bank
in loose soil, 3 feet above the bottom of the dry channel. The round
tunnel, from 60 to 75 mm. in diameter, led back for a distance of
375 mm. to end in a chamber 150 mm. in diameter, with the bottom
lined with bits of grass that formed a roughly, cup-shaped nest. The
two eggs, in which incubation had begun, were white in color, without
markings. One was broken in transportation. The other meas-
ures, in millimeters, as follows : 26.2 by 20.5.
The genus Teledromas Wetmore and Peters^* for the present
species is distinguished from Rhinocrypta Gray by its smooth, un-
crested head, relatively stronger, heavier bill; short under tail coverts
; and relatively longer hind toe and claw. In addition, it will be
noted that while T. fuscus made its nest in a tunnel in the side of a
cut bank, R. lanceolata^ as I have noted elsewhere, deposited its eggs
in a stick nest in a low shrub.
MELANOPAREIA MAXIMILIANI ARGENTINA (Hellmayr)

Four specimens of this bird secured (three skins and one in alcohol)
from the localities listed below, in the absence of comparative
material, are referred on the basis of range to the subspecies argentina.
W. D. Miller ^^ has with reason removed the present genus
from the Formicariidae to the Rhinocryptidae, in part on inf9rma-
tion from the bodies of the present specimens (preserved in alcohol)
as when, at his request, I examined these I found that they pos-
sessed four notches on the posterior border of the metasternum. It
may be added that the habits of these birds are not radically dif-
ferent from those of other tapaculos. Melanopareia ^^ was first taken
