by Underwood at Desamparados. It is a bird which cannot possibly 

 be mistaken for any other species, hence there can be no doubt as to 

 the validity of the record.

Six skins. 



Scattered pretty well over the whole country where suitable condi- 

 tions are to be found, although more abundant at lower altitudes. 

 They were quite abundant on the lagoon at the mouth of the Matina 

 River, where they were feeding among the water-hyacinths and run- 

 ning about on the water-plants. They always seem to be extremely 

 shy wherever found and are very hard to kill, not only from their 

 shyness, but from the fact that their skin is very tough, seemingly 

 impervious to a charge which would riddle most birds of the same 

 size. I saw a single bird in a pasture near Guapiles, others beside a 

 lagoon near Old Harbor, quite a number on the lower Sicsola River 

 and a single family of birds on Laguna Chiquita near Bonilla. 



They are very noisy, emitting harsh cries when alarmed, are strong 

 flyers, and have the curious habit of lifting their wings perpendicularly 

 to their fullest extent when standing on the ground.
