THE CLASSIFICATION OF BIRDS. 263 
follows the forty-third family—the Chatterers, Cotingide—the 
type of which is the Blue Chatterer, and which also contains 
the other interesting birds before mentioned by us '—namely, 
the Cock-of-the-Rock, the Umbrella-bird, and the Bell-bird. 
The next family group consists of the Plant-cutters, Phytoto- 
mide, a small group of South-American birds. To these 
succeed the Wattled Ant-thrushes, Philepittide, the Pittide, 
or Old-world Ant-thrushes, and the very small family of New- 
Zealand Wrens, Xenicide, with only five known species. 
The next and forty-eighth family, that of the Dendrocolaptide’, 
is the first family of the division Z'racheophone. It is the 
family of the Wood-hewers and Oven-birds*. To this succeeds 
the family of American Ant-thrushes*, or Formicartide, and 
after that the small families, Gnat-eaters, Conopophagide, and 
the Tapaculos or Pteroptochide (that might be called ‘ tilt- 
tails”), with which the second division of Passerine Birds 
terminates. 
The third division of the section Mesomyodi is formed by the 
Scrub-birds—the fifty-second family, Atrichiide. The trachea 
and vocal organs are as in the Oligomyode, but the sternum is 
quite exceptional. The fourth and last division, the Menure, 
consists only of the Lyre-birds—the family Menuride. It 
resembles the Oligomyode, as does the third division, but is 
entirely peculiar, in the downy clothing of its young. 
The divisions may be expressed in a tabular form, thus :— 
Order PASSERIFORMES.
