SETOPAGIS PARVULUS (Gould)
Cupriuiulgus jjomilus Gould, Proc. Zool. Soc. London, 1S37, p. 22. (Parana
River near Santa Fe, Argentina.)
Near the ranch at Kilometer 80, behind Puerto Pinasco, Paraii:uay,
these goatsuckers began to call suddenly on the evening of September
17, 1920, and it was supposed that they were migratory as none had
been recorded previously. On the following night, by means of an
electric headlight, tAvo of the nocturnal songsters w^ere taken, so that
their identity was established beyond question. Their song resembles
you cheery chu chu cliu chu chu chu^ the first two notes uttered in a
clear tone and the rest forming a bubbling, rattling trill. They
called from leafy trees in open pastures, or from the forest, or came
out to rest on the limbs of fallen trees along the borders of the monte,
•or in paths cut among the trees. Here the headlight caught their
eyes with a reflected glow of deep burning red, like a coal of fire
but more intense in color, a beautiful object against the dark back-
ground. At intervals this light disappeared, apparently as the bird
turned its head, and then came into view again. Never more than
one point was seen at a time so that vision seemed to be entirely
monocular. The species continued its notes until my departure.
It was reco-ded September 23 at Kilometer 110, and September 24
and 25 at Laguna Wall (Kilometer 200). None were found at
Puerto, Pinasco, itself.
In Spanish this species was known as cuatro cuero^ in Guarani as
uro-ooh^ while the Anguete Indians called it ka jee vay ta ta nee nm.
For various reasons one of the specimens secured was preserved
entire in alcohol. The other, an adult male, seems large as it measures:
Wing, 141.2: tail, 103; exposed culmen, 9.7: tarsus, 15.6 mm.
Comparative material is not at present available to decide the status
of this bird.
The rictal bristles in this species are remarkabl,y short.
HYDROPSALIS TORQUATA FURCIFERA (Vieillot)

(Paraguay.)
Specimens of this fork-tailed goatsucker from Argentina, Uru-
guay, Paraguay, and southern Brazil are distinguished from those
of northern and eastern Brazil by slightly larger size, and darker
coloration, Avith more buff on the abdomen so that the southern birds
should rank as a subspecies of 11. torquata.
At Victorica, Pampa, from December 23 to 29, 1920, this goatsucker
was fairly common in low open forests of calden and algarroba, where
