BATS OF THE BELGIAN CONGO 565 bat-k toward the pelvic ivgioii. The vocal cords, of course, arc also greatly broad- ened in proportion. Furthermore, they have one air sac on either side of the neck that can be inflated at 'will, as in certain frogs. Indeed, when the old males were in full assembly, their chorus made us think of a pondful of noisy American wood frogs, greatly magnified and transported into the tree-tops. The natives assured us that these poor males had to croak from sun- set to sunrise for the enjoyment of the females, supposedly deaf.

In the waning light they look more like glistening lumps of fungus than live creatures. They huddle together in great numbers, screaming and fighting for desirable positions
