seven eggs.'^ Seuor Roberto Dabbene puts tbe number at 

 four or five (Aiiales del Museo Nacional de Historia Natural 

 de Buenos Aires, tomo xxviii., p, 192). Curiously enough, 

 tlie measurements he gives are 42-1-4 x 30-32 mm., which 

 approximately are those of Podiceps ainericamis, whilst mine 

 are 45-i8 x 32-33 mm., or an average of 47 x 32 mm. We 

 are both agreed as to the shape: — " Elliptic, with the two 

 poles almost equal .'^ 



Catarrhactes chrysocome (Cat. B. xxvi. p. 365). 



As Hudson remarks, Penguins are well known to the 

 Gauchos along the coast; but more, I take it, from dead 

 than living examples. I myself have never seen one in the 

 flesh, defunct or otherwise. 



A very interesting dead specimen (an immature indivi- 

 dual) of this species was found by Mr. M. A. Ruunacles on 

 our sea-coast in July of 1914. He Vvas good enough to 

 carefully skin it and give it to me. In my turn I presented 

 it to the British Museum, where Mr. Charles Chubb duly 

 identified and welcomed the specimen, remarking that its 

 occurrence was of great interest. 



427. Rhynchotus rufescens Teumi. Great Tinamou. 



Ever since I came to this locality I ha\e known of the 

 " Perdiz Grande^' as a species entirely confined to the 

 Rincones, and, in a lesser degree, to the Atlantic coast-belt. 

 Formerly, on these occasions when I penetrated into our 

 Rincon Grande, I was always prepared for the sudden and 

 very startling flight of this handsome Tinamou, and might 

 count upon seeing two or three individuals. On the rough 

 and lonely sand-dunes of tlie coast it was much scarcer, 

 except perhaps in the immediate vicinity of Cape San 

 Antonio, where the Rincon and coast formations come into 

 juxtaposition. As a denizen of the "camp'^ proper it had 

 long ceased to be, witli the replacement of the pampa 

 and other giant grasses by finer pastures (indigenous, not 

 imported from Europe, as has been stated). From all I can 

 learn the local situation remains unchanged at the ju'eseut 

 date — a lew pairs maintaining their little-disturbed existence
