1^0 Barrows o?i Birds of the Lower Uruguay . | July 
yet there is a good deal of real music in it. Although I not 
unfrequently saw young unable to fly, I could never find the 
nest, but was convinced that it must be placed on the ground, 
at least normally. 
27. Foospiza lateralis ( Nordm .). — A single specimen of 
this species was taken at Concepcion, September 29, 1879. It 
was in company with another individual of the same species and 
several of the preceding. During the summer following I looked 
in vain for others, but late in the autumn (April 23), while 
hunting capybaras on a stream about a dozen miles west of this 
place, several were observed. As our charges at the time were 
of buckshot none were secured. The following September, 
when I was on the lookout for this bird, almost all the favorable 
ground was flooded, and I only caught a glimpse of one on a 
nearly submerged island among impenetrable thickets where he 
escaped the shot. 
The species seems to be but slightly known, and would appear 
to be only migrating at the points mentioned. 
28. Poospiza melanoleuca Vieill . — Although much bet- 
ter known than the preceding species, this bird was far from 
abundant at Concepcion. It was only met with in autumn on 
one or two occasions, and was found then among scattered 
trees and bushes on high ground, and in company with Syival- 
laxis , Zonotrichia , and some Gnatcatchers. 
It had the general motions and appearance of a Titmouse, 
thus differing widely from the other members of the genus. 
During the trip to the Sierras of the Pampas, and while in 
camp on the Pigue, about 25 miles from the town of Carhue, a 
Poospiza was taken which appeared to be another species (pos- 
sibly torquata ) , but it was moulting and was unfortunately after- 
ward lost. 
29. Phrygilus caniceps ( Burm .). — Only met with in the 
Sierra de la Ventana, where it was abundant in flocks, some of 
which numbered as many as a hundred individuals. When 
found near the base of the sierra they were almost always asso- 
ciated with the common Zonotrichia . Although most of them 
had not finished moulting, they were constantly singing and 
seemed perfectly contented with their desolate surroundings. 
30. G-ubernatrix cristatella ( Vieili. ) . Cardinal ama- 
rillo (Yellow Cardinal). — This is another well known cage-
