The Natural History Museum of Los Angeles County (LACM) is the repository for some 90,000 mammal specimens of world-wide provenance, and is particularly strong in its collections of Chiroptera. As the result of numerous collecting expeditions undertaken by one of us (KES) since 1954, a substantial representation of Australian bats has been assembled. It is our intent in this paper to bring these collections to the attention of our Australian colleagues, so that this biogeographic and systematic resource might be more widely used
