4GG ^Ir. C. 11. 13. Grant on Birds collected in Argentina, 



of us. On Sept. 9th, at Colonia llisso, a clutch of three eggs 

 was taken, the nest being a mere hollow in the open sand and 

 in close proximity to the nests of PJuiethusa ma(/nirostris 

 and Rhijnchops melanura. The eggs agree with a specimen 

 in the British Museum from Brazil, but are perhaps very 

 slightly paler in the ground-colour.

These specimens agree exactly with those in the British 

 Museum from more northern localities. 



This Oyster-catcher is common and resident on the 

 sea- coast, where it breeds on tlie sand-dunes. It has a clear 

 loud call and is by no means wild, especially when nesting. 

 The nest is a mere hollow scraped in the sand in sheltered 

 spots on the sand-dunes, and I have never taken more than 

 two eggs as a clutch.
