yellowish, tipped with black; upper parts of head and back
dull green; throat and upper part of breast bright emerald green in
scales, with metallic lustre; lower part of breast, belly, and tail dun
or bay colour; the feathers of the tail fringed and tipped with black;
primaries dark brown, with some purplish reflections. The four middle
tail feathers have greenish reflections on them. The female is rather
less, and wants the bright emerald throat, the whole under parts being
bay-coloured; the male had some white about the thighs. The known
species is the Ourissia humming-bird (Trochilus Maugeri. Lesson.).

Of the genus Turdus were procured two species, thought to be new. One
agrees very nearly with Le Merle de Paraguai, or Calandra, as described
in Vieillot, but it wants the white on the wings. The other is a good
deal like the Turdus Plumbeus, as described by the same author. The
first is quite common throughout Yucatan, but the second is rather
rare.

Of the genus Loxia were obtained four species, three of which are in
immature plumage, and cannot, therefore, be placed with certainty. The
other does not appear to have been described, though there are some
descriptions which come near it. The male is nearly ten inches long;
head and chin, extending down the sides of the neck, and in a crescent
across the upper part of the breast, black; cheeks very dark steel
gray; a white line extending from the bill over the eye almost to the
hind head; hind head, back, secondaries, outer edge of the primaries,
yellow olive; also the tail; the shafts of the feathers are black; part
of the chin and throat pure white; breast, belly, and thighs cinereous;
vent, and under the tail coverts, light bay; bill quite stout, nearly
an inch long, and black; the female is about nine inches long, having
dark cinereous brown in place of the olive; the other markings much the
same as the male, but not so vivid. They are very common throughout
Yucatan, and said to be very destructive in the fields and gardens:
called by the Indians _tsapin_.

Of the genus Emberiza one was procured, in immature plumage; probably
the painted bunting.

Of the genus Pipra one: the blue and yellow manakin, not common in
Yucatan.

Of the genus Tanagra were procured two species, one of which is the
red-crested tanager of Latham. But one pair was seen. The other is
believed to be undescribed. The specimen was a male, six inches and a
quarter long; bill inflated, and
