186. C CXiliS, Vig. and Hors. (including also C. ruficeps, C. lineo- 



capilla, and C. isura), Grass-Warbler. 



Sandy buff, much striped. 



According to Dr. R Bowdler-Sharpe, C. ruficeps (Rufous- headed 

 Grass Warbler), C. lineocapilla (Lineated Grass- Warbler), and C. 

 isura (Square -tailed Grass-Warbler) are seasonal and sex variations 

 of C. exilis. "In Australia the full-plumaged males have rufous 

 heads, the females striped heads, and the winter plumage of both 

 sexes appears to be blackish, with streaked backs and heads. C. 

 ruficeps is adult male ; C. exilis is the bird iu full winter plumage, 

 while C. isura is only the square-tailed summer-plumaged birds."
