title: Observations on the vomeronasal organ of the colugo Cynocephalus (Mammalia, Dermoptera).
abstract: This paper presents the first description of a functional vomeronasal organ in the colugo or 'flying lemur' Cynocephalus, the sole living representative of the order Dermoptera (Mammalia). The vomeronasal organ complex comprises patent nasopalatine and vomeronasal ducts, a 10-mm-long epithelial tube consisting of an 8- to 10-cell thick, 65-microns-tall neurosensory epithelium, the vomeronasal nerve, and the accessory olfactory bulb. The vomeronasal glands are sparse. Among mammals, the vomeronasal organ of the colugo is one of the relatively longest, at nearly 48% of nasal cavity length. It is exceeded among archontans (colugos, bats, primates, and tree shrews) only by that of the strepsirhine primate Microcebus murinus.
