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 Guiana as far as the south bank of the 
Kio Negro; on the opposite or north bank of the Bio Negro 
Psophia ochroptera is found; beyond the next great rivers, Japura 
and lea, Psophia napensis occurs ; on the south bank of the 
Amazon, west of the Madeira, we have the beautiful Psophia 
leucoptera ; east of the Madeira this is replaced by Psophia 
riridis, while near Para, beyond the Tapajoz, Xingu and Tocan- 
tins, there is another species, Psophia obscura. 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. Yol. II. p. 28.)

The Eurypygidte, 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, 
Ewrypyga (2 sp.), ranges from Central America to Brazil
