ide. The
third species was not seen in the wild state, the only specimen
procured being given to Dr. Cabot, alive, by the padre Curillo, of
Ticul. It is the Psittacus Macao (Ind. Orn., vol. i., p. 82), red and
blue macaw (Gen. Syn., i., 199).

Of the genus Ramphastos one specimen was procured, the yellow-breasted
toucan (Gen. Syn., vol. i., p. 326), Ramphastos Tucanus (Ind. Orn.,
vol. i., p. 136). This specimen does not agree with the description in
Latham, but is the same as the one described by Mr. Edwards from a
living specimen in Lord Spencer's collection. It was procured at Uxmal
on the day when Dr. Cabot went down to the hacienda to operate on an
Indian's leg. Two or three different species were afterward seen at
Macoba, but Dr. C. did not succeed in killing any of them.

Of the genus Momotus were obtained two species: the first, the common
Brazilian or blue-headed motmot; this was quite common in Yucatan, but
not so common as the other, as to which it is doubtful whether it has
been described. It is about the same length as the blue-headed, but the
tail is longer in proportion to the body. The markings on the plumage
are very different from those of the Brazilian; there is a black stripe
extending down from the chin to the middle of the breast, bordered on
each side with light blue; a broad, light blue, almost white, stripe
extends over the eye from the base of the bill almost to the hind head.
The general colour is a sort of greenish bay; primaries and tail light
green, tipped with black; the two central feathers of the tail much
longer than in the Brazilian, having the shaft bare to a much greater
degree, and the feather at the tip is bright pale green, tipped broadly
with black.

Of the genus Crotophaga one species was procured, the lesser ani
(Crotophagi Ani. Ind. Orn., vol. i., p. 448). These were very abundant
in all parts of the country.

Of the genus Oriolus, including under this denomination Icterus and
Cassicus, were procured five species, one of which is supposed to be
new, three doubtful, and one known. The male of the new species is nine
inches and a half long; head, neck, cheeks, breast, belly, rump,
tertiaries, and nearly the whole length of the outer tail feathers and
the lower part of the third, and occasionally a stripe on the fourth,
bright chrome yellow; face, throat, primaries, secondaries, back, and
four, and sometimes six tail feathers, black; legs bluish; bill black,
except the base o
