The cranial skin covered by the band appears naked (although a sparse coat of fine hairs can be seen under magnification), and it is fully exposed only when the ears are drawn forward.

One of the specimens that we collected at Paracou—AMNH 267414, an adult malehas a welldefined, hairless fossa on the top of the head between the ears and behind the interauricular band (fig. 30). Smooth and glabrous inside, this pit is surrounded by a rim of skin with coarse projecting hairs, exactly as Pirlot described. Although no histological work has yet been done, this structure appears to be a glandular pouch or a pouch in which glandular secretions might be stored. To the best of our knowledge, this structure is unique among bats (for a summary of known chiropteran glandular structures, see

Note the pale ventral fur, the long hairs on the leading edge of each pinna, and the very deep, Vshaped notch in the interauricular band; the cutaneous fossa is visible through the notch in the interauricular band. The hairs covering the fossa in this view are rooted in the skin surrounding the fossa, and on the underside (posterior surface) of the interauricular band; the fossa itself is hairless.
