The Andean moun- Pacific slopes (particularly the higher portions) are tain chain affects these distributions both as a barrier not arid, there are a few relatively low passes across and as a creator of habitat differentiation. Three the Andes, and the upper portions of certain Amazo- main distributional areas are distinguished, the nian tributaries are arid.

Because they were collected entirely and distribution of Peruvian bats with particular by netting, some groups (e.g., Glossophaginae, attention to altitude.

The main emphasis is on phyl- information. In many cases, Tuttle gave only lostomatid bats.
