of these birds in the British Museum. These seven species are spread over nearly the 
same area as the members of #ucco, and extend from Eastern Guatemala to South- 
eastern Brazil. They are inhabitants of the hot forests of the lowlands wherever they 
are found. 
The bill in Malacoptila is much more slender than in Bucco, the culmen gradually 
curved for most of its length, but rather more abruptly towards the tip; there is no 
hook nor any notch at the end of the tomia in either maxilla or mandible. The nostrils 
are open but deeply sunken and overhung by long curved bristle-like feathers; the 
rictal bristles are strong and long; the feathers from the rictus are long and pendent, 
and often conspicuous from their white colour. The wings are short and rounded, the 
tail moderate and rounded, the feet feeble. In several species, notably those of 
Central America, there is a marked difference of colour between the sexes, the males 
being of a ferruginous tint, the females greyer. Moreover there seems to be a 
considerable amount of local and individual variation. Of the two species found 
within our limits, 1/7. énornata marks the northern extension of the genus, and spreads 
from Guatemala to Nicaragua on the eastern side of those countries; JZ. panamensis 
takes its place in Costa Rica, and is found thence as far south as Venezuela, Ecuador, 
and Peru.
