We now come to that section to which Bonaparte gave the generic name of Pygmornis.
As the term implies, these birds are all extremely diminutive; so minute, indeed, are they, that, if subjected to the balance, their tiny bodies must be weighed by grains. That these mites of birds perform some important office in the scale of nature is certain, from the number both of species and individuals: they are very widely dispersed over every part of the great country which is inhabited by this extensive family of birds; with the exception of one species, however (the P. Adolphi), they all fly to the southward of the Isthmus of Panama. How minute must be the insects taken by these diminutive birds, how perfect must be their vision, and how delicately sensitive must be their tongue!
The only external difference between the sexes consists in the longer and more graduated tails of the females; in colour they are as nearly alike as possible.
Pygmornis Longuemarei
Habitat: Cayenne, Guiana, Trinidad, and the eastern part of Venezuela.
Pygmornis Amaura
Habitat: Banks of the River Napo
Pygmornis Aspasiæ
Habitat: Brazil and Peru
Pygmornis Adolphi
Habitat: Central America
“This,” says Mr. Salvin, “is an abundant species in the forest about Yzabal, but the density of the under growth renders it extremely difficult to obtain a shot at so small and active an object. The bird is by no means shy, and takes but little notice of an observer—even searching the flowers almost within arm’s reach for the insects and honey therein contained. In movement it is extremely elegant and graceful, and, flitting from flower to flower, shows its beautifully-formed tail conspicuously in every motion. Like all others of its family, it selects a small twig for its perch, giving preference to a dead one. While at rest it trims its feathers dexterously with its bill, which every now and then it cleans by rubbing it first on one side and then on the other of the twig on which it stands.”—Ibis, vol. i. p. 127.
Pygmornis griseogularis (Gould)
Habitat: New Granada; and Ecuador?
In my description of this species I have inadvertently stated that it has a crescent of black across the breast, which is not the case.
Mr. Bell of New York informs me that he has heard the “little Pygmornis of Panama” (by which I believe the present bird is intended) “sing beautifully, the notes forming a soft, shrill, and pretty song.”
Pygmornis striigularis (Gould)

Pycmornis Idallæ

Pygmornis nigricincta
Habitat: The forests bordering the upper part of the River Amazon
Pygmornis Episcopus (Gould)
Habitat: British Guiana
Pygmornis rufiventris
Habitat: Cayenne

The above list of synonyms are given on the authority of Dr. Cabanis: it is just possible that they may refer to the female of my P. Episcopus; but I fear that this cannot at present be satisfactorily determined.
Pygmornis Eremita (Gould)
Habitat: Northern Brazil, Bahia, the banks of the Lower Amazon
Pygmornis pygmæa
Habitat: South-eastern Brazil
