as frequently pursuing their prey on trees and herbage as on the ground. The typical tiger-beetles, or Cicindelæ, inhabit only open and sunny situations, and are wholly terrestrial in their habits. They are the sole forms of the family which occur in the Northern and Central parts of Europe and North America. In the Amazons region, the shade-loving and semi-arboreal Odontocheilæ outnumber in species the Cicindelæ as twenty-two to six; all but one of this number are exclusively peculiar to the Amazonian forests, and this affords another proof of the adaptation of the Fauna to a forest-clad country, pointing to a long and uninterrupted existence of land covered by forests on this part of the earth's surface.
We left this place on the 8th of January, and on the afternoon of the 9th, arrived at Matarí, a miserable little settlement of Múra Indians. Here we again anchored and went ashore.
