* Nova Coimbra (lat. 19° 55 ; ) is a presidio founded in 

 177^, and is probably the most southern Portuguese set- 

 tlement on the Rio Paraguay. In different Spanish and 

 Portuguese maps, the Yaguary (Menici, Monici), a large 

 tributary stream of the Parana, is usually fixed on as the 

 frontier between Parana and Paraguay toward the east 5 

 toward the west sometimes the Chichuy (Xexuy) and Ipane, 

 near the ancient mission of Belen (lat. 23° 32'), sometimes 

 the Mboimboy (lat. 20° 27 7 ), opposite the destroyed mission 

 of Itatiny, and sometimes (lat. 19° 35'), the Rio Mondego 

 or Mbotetey, near the destroyed town of Xerez ; all three 

 tributary streams of the Paraguay on it's eastern side. The 

 boundary nearest Nova Coimbra, that of Rio Mboymboy, 

 has been pretty generally adopted provisionally between 

 Brazil and the ancient viceroyally of Buenos Ayres.
