. A history of North American birds [microform] : land birds. Birds; Ornithology; Oiseaux; Ornithologie. —THE GROUND-TITS. 83 Family CHA^MABM. — The (iROUND-Trrs. Char. Bill compressed, short, rather conical, not notched nor decurved. Ciilmen shnrp-rid^'ctl. Nostrils linear, with an inciunbcnt scale. Rictal bristles reaching beyond , which are scantily overlnnig by bristly leathers. Loral feathers brisHy and directed forwards. Tarsi booted, or covered with a continuous plate anteriorly, with faint indications of scutelliv on the inner side. Basal joint of middle toe attached for about half its length on either side. Primaries ten; quill longest. Plumage very lax. We have found it impossible to assign the genus Chamcca to any recog- nized fouiily of American birds, and have accordingly been obliged to give it indejjendent rank in this re- spect, althougli it may prop- erly belong to some Old World group witli which we are not acquainted. In its general appearance it ap- proaches the I'arukc in loose plumage, bristly lores, want of notch to bill, etc.; but differs in the very mucli bristled rictus, sharp-ridged culmen, linear nostrils, booted tarsi, less amount of adhesion of the toes, etc. It approaclies the Sijlviidw in the sharp-ridged culmen and bristly gape, but is otherwise very different. The excessively rounded wing is a pecu- liar feature, the sixth primary being the longest. The family may, perhajvs, be best placed between the SyiviidoG and Pnridcp. This family has but one representa- tive (Chaiiiwafascmta), and tiiis con- fined to the coast region of California. Tlie characters of the genus are those of the family.
