Two molossids, Cheiromeles torquatus and C. parvidens, display a number of morphological characteristics that appear unique among Chiroptera. In this study, adult specimens of both species (fluid-preserved and skeletons) were examined using a dissecting microscope and camera lucida. Several unique morphological features are described in detail for the first time with comments on their possible functions. These include a hallux (digit I) that is positioned at a right angle to digits II-V, a calcar that is bound to m. gastrocnemius, and a modified m. tensor plagiopatagii which appears to function like a drawstring to close a pair of subaxillary 'pouches'. The function of these structures and additional characteristics of the limbs appear related to terrestrial and arboreal locomotion exhibited by these bats.
