The fourth secti ises eae :
ection comprises the species constituting my genus

SELENIDERA,
WITH THE FOLLOWING CHARACTERS -—_

Rostrum brevius et amplius quam in genere Pteroglosso; cauda ratione ad magnitudinem corporis habit4 brevior :
sexus inter se colore dissimilis; mare caput pectusque nigra, foemind has partes castaneas habente ; plume

auriculares flavee; lunula ad cervicem posticam flava.

Bill shorter and thicker than in the genus Pteroglossus ;

tail shorter in proportion to the size of the body; sexes

differing in colour ; the male having the head and breast black, the same parts in the female being chestnut ;
g ches ;

ear-coverts and a crescent at the back of the neck yellow.

This interesting group of Toucanets again have a more restricted range than either the typical

Ramphasti or Pteroglossi. No one of them has yet been found so far to the northward as the Isthmus of

Panama; and few of them have been observed beyond the latitude of the Amazon in this direction. On

the banks of that river, however, and those of the Rio Negro and Rio Madeira, they are very numerously
dispersed ; and one species, the Selenidera maculirostris, is found as far south as Rio de Janeiro, and
I believe in Corrientes and Paraguay ; still the forests bordering the Upper Amazon and its tributaries

are undoubtedly the cradle of the race. They constitute a well-marked section of the family, and are
distinguished by their small size, by their short bills, by the crescentic mark of yellow at the base of the
neck, and by the brilliant colours which adorn their ears and flanks. The females have all these character-
istic marks, but differ conspicuously in the colouring of the anterior half of their bodies, which is generally

chestnut-brown instead of black.

The species are—
