 name Terutero {Terittero. Azara). — This plover is common at 

 Ytanu and increasing there in numbers. 



27. Gallinago paraguaim (VieilL). Paraguay Snipe (^ecasf/i(X. 

 Azara). — This snipe is closely allied to G. frenata of my 

 Uruguay list, and the eggs and situation of nest are very

Three clutches of eggs of three each, the usual number laid

 Paraguay, however, they seem to lay more eggs, ten having 

 been sent me from one nest, while four is the usual number 

 in Uruguay.
