Scheffer noted that the long-eared bats at Boulder Cave were nearly ready to give birth to young on July 12, 1930, and were carrying naked young a week later. On July 7, 1936, at the same locality, females contained nearly full-term embryos. [Illustration: FIG. 43. Distribution of the long-eared bat in Washington.
