1'j4 Mr. C. H. B. Graut on Birds collected in Argentina, 



The November specimens are very much worn and that 

 from Bella Vista has started its moult. 



Many individuals of this Thorn-bird were observed at 

 Colouia Mihauovitch and several nests were examined, but 

 none contained eggs, though the female shot on the 5th of 

 November was laying. 



The nest is a fair-sized structure of sticks suspended 

 from the overhanging branches of a tree, the entrance 

 being from below and the nesting-chamber near the top.
