[part I. 



the Syloiidie in t!ie sbarp-ridgod culrnen and bristly gape, but is 

 otherwise very ditfercii;;. The excessively rounded wing is a peculiar 

 feature, the sixth primary being the longest. 



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

 Pai'idae. 



CHAM.SA, GAMBEii. 

 Chnmxa, Gambel, Pr. A. N. So. Ill, 1847, 154. (Type Parua fasciatm.) 



Bill much shorter than head, conical compressed. Culmen much curved ; 

 gonys less so. Nostrils linear, covered and nearly hidden by an incumbent 

 scale, as in some Wrens. Wings much rounded, about two-thirds the tail ; 

 the 6th primary longest ; the 3d equal to the secondaries. Tail very long and 

 much graduated, the lateral feathers not two-thirds the central ; feathers nar- 

 row, with narrow outer weba. 



The genus, as far as known, embraces but a single species.
