FAMILY CHAMÆADÆ.—THE GROUND-TITS.

CHAR. Bill compressed, short, rather conical, not notched nor

decurved. Culmen sharp-ridged. Nostrils linear, with an incumbent

scale. Rictal bristles reaching beyond nostrils, which are scantily

overhung by bristly feathers. Loral feathers bristly and directed

forwards. Tarsi booted, or covered with a continuous plate anteriorly,

with faint indications of scutellæ on the inner side. Basal joint of

middle toe attached for about half its length on either side.

Primaries ten; sixth quill longest. Plumage very lax.

We have found it impossible to assign the genus _Chamæa_ to any

recognized family of American birds, and have accordingly been obliged

to give it independent rank in this respect, although it may properly

belong to some Old World group with which we are not acquainted. In

its general appearance it approaches the _Paridæ_ in loose plumage,

bristly lores, want of notch to bill, etc.; but differs in the very

much bristled rictus, sharp-ridged culmen, linear nostrils, booted

tarsi, less amount of adhesion of the toes, etc. It approaches the

_Sylviidæ_ in the sharp-ridged culmen and bristly gape, but is

otherwise very different. The excessively rounded wing is a peculiar

feature, the sixth primary being the longest.

[Illustration: _Chamæa fasciata._]

The family may, perhaps, be best placed between the _Sylviidæ_ and

_Paridæ_.

This family has but one representative (_Chamæa fasciata_), and this

confined to the coast region of California. The characters of the

genus are those of the family.
