Tris dark. 
Although for several days I stalked these birds, hearing their 
call, yet I could only manage to secure one specimen in the dense 
forest.

Tris sepia. 
This bird flies in flocks, and is usually observed in close juxta- 
position with a flock of the Guia piririgua in the open country on 
the outskirts of the cultivated ground, where it perches on bush 
or hedges.

Iris deep orange. 
The native name of this noisy bird is ‘‘ Uraca;”’ and it is found 
abundantly all over the Republic, commonly flying in flocks of six 
or seven. Here, in a willow tree, a nest was discovered, built of 
twigs, containing seven eggs, which was quite open above, with a 
very deep basin, and was lined with dry leaves, principally of the 
“ Eucalyptus ;” but in other provinces different leaves are em- 
ployed. The Uracas are sometimes tamed and kept in houses to 
rid them of insects; but their noise and dirty habits disqualify them 
for occupying the position of favourites. 
The egg is of an oblate spheroidal form, equally blunted at both 
ends, with a slightly raised white chalky network equally diffused 
over a pale green ground. 
Meas.: axis 42 millim., diam. 32 millim.

Iris crimson. 
I found this tame bird rather rare round here, but usually met 
with it in the dense woods, where, on account of the slowness of its 
movements, it was easy to shoot, although difficult to distinguish. 
Very seldom seen in flight, it hops trom twig to twig, using its 
fine tail at the end of the leap to steady its perch. 
146. Coccyzus minor (Gm.). 
3. Salto, Buenos Aires, Arg. Rep., Oct. 17, 1881. 
Iris dark. 
Not uncommon in the province of Buenos Aires, especially about 
Monte Grande; but in other parts of the Republic I do uot 
remember often having met with it. Its nest is built in low trees 
or hedges, much resembling that of the Dove in outward appearance,
