✦ Synopsis

TWO PLATES (EIGHT FIGURES)

* In general, members of the class Chiroptera hare a small opening in the wall of the periovarial sac (Robin, 1881). In the genus Vesperugo, however, Gerhardt ('04), and Van Beneden (1880) find that the capsule is closed. With these findings, Robin (1881) does not wholly agree.
