192 CATLOGUE OF 



I have observed specimens with the frill or ruff fully 

 developed in February and March, and on one occasion 

 as soon as January 18th. 



The nest of this species is a large accumulation of 

 the stems of the reed amongst which it is built, the 

 whole of the structure, together with its contents, being 

 perpetually moist. 



In three or four instances where I have closely

The specimens in the case were obtained on Hick-

SANDWICH TEKN. (MATURE SUMMER.) 

 Case 251.

 Fern Islands in June, 1867.
