 blue-and-yellow macaws flew over this camp. They were 

 plentiful enough to form a loose flock, but each pair kept 

 to itself, the two individuals always close together and 

 always separated from the rest. Although not an abun- 

 dant, it was an interesting, fauna which the two naturalists 

 found in this upland country, where hitherto no collections

 several species of opossums, mice, and rats which were new

 any of our birds are so remote that it is hard to describe 

 them save in technical language. Finally, among these 

 unfamiliar forms was a veery, and the sight of the rufous- 

 olive back and faintly spotted throat of this singer of our

 rolling stretches of low forest. Midway on our journey 

 we crossed a brook. The dogs minded the heat much. 

 They continually ran off to one side, lay down in a shady
