Notes:
Skin samples from 16 genera and 19 species of bats were studied histologically. These and review of the literature revealed musculi arrectores pilorum composed of smooth muscle present only in Megachiroptera and complex cutaneous striated muscle systems best developed in Microchiroptera. Smooth muscle arrectores of the mid-dorsal neck skin of Hypsignathus monstrosus are described in detail and resemble those of generalized structure in other mammalian Orders. Shoulder pouches of the epaulet bats (Epomophorus and Epomops) contain compound smooth and striated muscle systems for eversion of hair tufts and pouch respectively. An evolutionary trend within the Chiroptera of reduction in smooth muscle arrectores and replacement by integumentary striated muscle fibers is suggested.
