called at intervals with the usual sonorous notes of this species. 

 The birds were observed here from November 27 to December 3. 

 Near Lazcano, Department of Rocha, Uruguay, one was seen Feb- 

 ruary 7, 1921, and near Concon, Chile, several were noted on a small 

 slough on April 25. 



One harboring the old delusion that grebes possess no tails has 

 only to watch the present species during the breeding season to be 

 undeceived, as at that time males frequently swim about truculently 

 with the short tail held erect, so that it is very prominent. In diving, 

 the birds, if not frightened, often lower the fore part of the body 

 and then sink slowly beneath the surface, turning the head about 

 for a last view, before they finally disappear without leaving a ripple 

 on the water.

The black-browed albatross, common off the coast of Brazil below

 numbers in the great mouth of the Rio de la Plata on June 20, below 

 Montevideo. On January 23, 1921, I found a skull of this species 

 cast up on the beach near La Paloma, Department of Rocha,

On May 2, 1921, I collected the skull of a giant fulmar on the 

 beach at Antofagasta, Chile. Like many of the other birds cast up 

 by the waves at this place, the bird was covered with crude oil, sug- 

 gesting that it had been killed through becoming saturated with oil 

 floating on the sea.

 meters south of Cabo San Antonio, Province of Buenos Aires. The
