FURNARIUS CUNICULARIUS. G. R . Gray. (Male.)
Tongue, trachea, and oesophagus, as in Uppucerthia. Proventriculus longer, and slightly contracted
at its entrance into the gizzard, which is large, flattened, and muscular, more rounded than in
Opeiiorkynchus, lined with a rugose hardened coat, and filled with small seeds, and the remains
of insects ; intestines of small diameter, and furnished with two rudimentary cæca.

Sternum of nearly equal breadth, both posteriorly and anteriorly, but much narrowed in the
middle, the portion to which the ribs are attached much elongated beyond their junction ;
posterior margin furnished with two deep fissures, slightly narrowed at their exit ; keel deep,
slightly rounded on its inferior edge, and much scolloped out anteriorly; pelvis broad and short,
the os pubis projecting far backwards; the ischium terminating posteriorly in an acute process.
Os hircatum thin, much arched, furnished with a flattened reflexed process at its junction with the
sternum ; the points of the rami bent forwards at their junction with the coracoids.
Coracoids of moderate size and length, inserted deeply into the sternum ; scapula of moderate size,
broader near the extremity.

UPPUCERTHIA DUMETORIA. Geoff. I f D'Orb . (Female.)
Tongue short, compared with the length of the bill, pointed, armed ivith a few spines at the base ;
trachea of moderate size, acted upon by one pair of stemo-tracheal muscles, which go off to’
the sternum, about ^ of an inch above the inferior larynx; from the upper ring of the bronchim
on each side, a process proceeds upwards to the point from which the muscles diverge, to
which point only the rings of the trachea are continued, two spaces therefore, one on the
anterior, the other on the posterior side of the trachea, immediately above the bronchim are
left devoid of osseous matter, being bounded laterally by the process above mentioned, inferiorly
by the upper rings of the bronchim, and superiorly by the lower ring of the trachea, which is
slightly enlarged; cesophagus small, slightly dilated a little above the proventriculus, which
is of moderate size, and not contracted before entering the gizzard ; gizzard large, oval, very
muscular, inner coat hardened, deeply furrowed longitudmally, and filled with the remains of
insects; intestinal canal of moderate size, without cteca; rectum very slightly enlarged ■
liver bilobed. ^ ’

With the exception of being larger than Furnarius cunicularius, and in having the bill more
bent and longer, the skeleton presents no material difference from that of the above-named bird.

OPETIORHYNCHUS VULGARIS. Gray. (Male.)
The structure of the soft parts, both in this species of Opetiorhynchus, and the two following
ones, so closely resemble that of Furnarius and Uppucerthia, that one description will almost serve
for the whole; those differences that do exist being not more than are generally found in species of
the same genus; the external characters also being slight, I cannot but doubt the propriety of
separating them; the cffica are slightly developed in this species, measuring ^ inch in length.
