f lower mandible, which is bluish; sings finely.
Female eight inches and seventh eighths long; marked like the male, but
not so brilliant; irides hazel. One of the doubtful comes very near to
Latham's description of the lesser Bonana bird (Oriolus Xanthornus.
Ind. Orn., vol. i., p. 181), but is an Icterus, and differs in some
particulars of plumage. Another of the doubtful resembles closely the
black oriole, and another the black cassican, but is smaller. The known
species is the St. Domingo oriole (Oriolus Dominicensis. Ind. Orn.,
vol. i., p. 182). Two specimens of this bird were procured, being the
only two that were seen.

Of the genus Cuculus, including Polophilus, were procured two species.
One resembles somewhat the bird described by Latham as the variegated
coucal (Polophilus Variegatus); the other the Cayenne cuckoo (Cuculus
Cayanus. Ind. Orn., vol. i., p. 221). These were both quite abundant
throughout the country.

Of the genus Picus were procured three species, two of which are
perhaps new. One of these resembles the little woodpecker of Europe
(Picus Minor) very closely. The other resembles Latham's description of
the Brazilian woodpecker (Picus Braziliensis). The known one is the
lineated woodpecker (Picus Lineatus. Ind. Orn., vol. i., p. 226).

Of the genus Certhia were obtained two species, of one of which no
description has been found, though Dr. Cabot was under the impression
that he had seen specimens of it in some of the cabinets of Europe. It
is three inches and seven eighths long; top of head, neck, and back,
dark brown, each feather having a light, buff-coloured, pear-shaped
mark in the centre; chin light buff colour; breast and belly light
brown, each feather having also a light buff-coloured mark down the
centre; primaries, secondaries, tertiaries, and tail dun-coloured; bill
one inch and three eighths along the ridge, and one inch and five
eighths along the gap, bent in its whole length, and horn-coloured.
They were not numerous. The other species is the yellow-bellied
nectarinia (Nectarinia Flaveola. Vieill., Ois. Dor. Certh., plate 51,
p. 102). They were quite numerous at Cozumel, where two specimens were
procured. They were not seen in any other part of the country.

Of the genus Trochilus were procured two or three species, one of which
is undescribed; another is probably the young of the same, and one is
described. The undescribed, male, is four inches long; bill six eighths
of an inch,
