Ticul, and was still alive in November,
1842. The other is the Penelope, or Phasianus Paragua (Ind. Orn., vol.
ii., p. 632). They are common in all parts of Yucatan, where they are
called chachalacha, from the noise they make, which is perfectly
astounding, and also bach by the Indians. They have a most remarkable
arrangement of the trachea, which passes down on the external surface
of the muscles, between them and the skin, in a long loop as low as the
pubis, and then passes up on the other side, and enters the thorax.

Of the genus Crax two species were obtained; the red curassow (Crax
Rubra, Lin., vol. i., p. 270), and C. Globicera (globose curassow).
They are found throughout the country, and are called by the natives
kambool.

Of the genus Tinamus one species was obtained, the variegated tinamou
(T. Variegatus). They are quite common throughout Yucatan, where they
are called by the natives partridges. They are kept tame in many of the
houses, being very useful in destroying scorpions, &c.

Of the genus Onyx one species was obtained, which, as far as the
plumage and size go, is undescribed, but it has the same note, habits,
&c., as our quail or partridge. It is smaller; the throat of the male
is jet black, and most of the markings are different, though having a
general resemblance to the Ortyx or Perdix Virginianus. They are very
numerous in all parts of Yucatan.

Of the genus Cancroma one specimen was procured, the cinereous
boatbill, which was killed at the senote at Chichen.

Of the genus Jacana also one species was obtained, the variable jacana
(Parra or Jacana Variabilis. Ind. Orn., vol. i., p. 763). It was killed
at Uxmal, at one of the small aguadas, and was the only one seen in the
country.

Of the genus Gallinula Dr. Cabot procured two species, the Cayenne
gallinule (G. Cayanensis. Ind. Orn., vol. ii., p. 767) and the
black-bellied gallinule (G. Ruficollis. Ind. Orn., vol. ii., p. 767).

Of the long-billed wren one specimen only was seen. The violet-headed
trogon was more common, several having been procured in different
places.

Besides the birds enumerated above, the following list comprises those
which were procured in Yucatan, and which are found also in the United
States, and have been well described by different naturalists.
