The remarkable and beautiful birds called Trumpeters, are 

 confined to the various parts of the Amazon valley ; and it is an 

 interesting fact, that the range of each species appears to be 

 , bounded by some of the great rivers. Thus, Psophia crepitans 

 inhabits the interior of Giuiana as far as the south bank of the 

 Eio Negro ; on the opposite or north bank of the Eio i^egro 

 Psophia ochroptei^a is found; beyond the next great rivers, Japura 

 and I^a, Psophia napensis occurs ; on the south bank of the 

 Amazon, west of the Madeira, we have the beautiful Psophia 

 leucop)tera ; east of the Madeira this is replaced by Psophia 

 viridis, while near Para, beyond the Tapajoz, Xingu and Tocan- 

 tins, there is another species, Psophia ohscura. Other species 

 may exist in the intervening river districts ; but we have here, 

 apparently, a case of a number of well-marked species of birds 

 capable of flight, yet with their range in certain directions 

 accurately defined by great rivers. (Plate XV. Vol. 11. p. 28.) 



Family lll.-EURYPYGID^. (1 Genus, 2 Species.) 



The Eurypygida3, or Sun-Bitterns, are small heron-like birds 

 with beautifully- coloured wings, which frequent the muddy 

 and wooded river-banks of tropical America. The only genus, 

 Euryjyyga (2 sp.), ranges from Central America to Brazil.
