As part of a study of the mammalian fauna of the kingdom of Saudi Arabia, a number of interesting bat specimens have been collected. The Egyptian fruit-eating bat, Rousettus aegyptiacus, and the Greater mouse-tailed bat, Rhinopoma microphyllum, are recorded for the first time from the country. Distributional notes and comments on the biology of these two and on five other species of bats from Saudi Arabia are mentioned. Previous distributional records of the other eight species known from the country are summarized. A map showing collecting localities is included.
