le owl, about six inches and a half long, of a tawny colour,
lighter beneath, which was shot near Merida. The second is about six
inches long, of a brown above and lighter beneath, called by the
natives tiquim thohca. Several specimens of both these owls were seen.
The third was caught in one of the ruined buildings, and kept alive for
a little while, but afterward escaped. It resembled somewhat the Strix
Aluco of Europe. One was afterward shot at Sabachshe, but was so much
injured that it could not be stuffed.

Of the genus Corvus were procured three species, two of which are
apparently not described. The first is a very beautiful jay, the head
and belly black; back, wings, and tail of a beautiful blue; the bill of
the male is yellow, and of the female black; the legs yellow. It was
first seen and shot near Sisal, on the way up to Merida, and afterward
several other specimens were obtained in different parts of the
country, for they are numerous throughout Yucatan. The other was first
met with at Uxmal, where a female was shot, and afterward two males.
They are of a dark brown on the head, neck, back, and tail; belly
white; bill of male black, and female yellow; they have a most singular
formation of the trachea, there being a sort of membranous sack or bag
coming off in front of the trachea at about the middle of its length,
and intimately connected with the skin of the neck; this formation,
together with the great muscularity of the larynx, may account for
their excessively loud and disagreeable cry. The other jay is the
Corvus Peruvianus, Peruvian jay. (Shaw, vol. viii., plate 27.) This
most beautiful bird is found in great abundance in almost all parts of
Yucatan, which is probably its native country, as it is mentioned as
rare in Peru.

Of the genus Psittacus were procured four species, three of which have
been described, and perhaps the fourth also; but, as the specimen is
bad, it is not easy to ascertain positively whether it has or not. One,
the Psittacus Albifrons (Ind. Orn., vol. i., p. 119), white-crowned
parrot (Shaw vol. viii., p. 519), is very numerous throughout Yucatan.
It is a beautiful bird, coloured with green, blue, red, white, and
yellow. Another, supposed to be the Psittacus Guianensis (Gen. Lil.,
vol. i., p. 323), the green parrot of Guiana (Gen. Syn., i., 231), is
not so abundant as the last, but still quite numerous. The specimens
were procured at Ticul, and some were afterward shot near Iturb
