The nose-leaf—the striking charac- teristic of the head in the Megadenns—is entirely wanting, unless indeed we may, with Professor Gei"vais, regard the groove which runs up the face from the nose to the forehead as really representing a sunken nose-leaf. This groove, or furrow, is a deep depression, increasing both in width and depth as it runs backwards, and is of such extent as to leave traces of its existence even on the underlying bones. In its posterior part the floor of the depression is divided lengthwise by a narrow ridge, and its sides are margined, as far back as the eyes, with peculiar horizontal cutaneous appendages. It is thus, evidently, a somewhat difl'erent manifestation of the tendency towards a peculiar development of the cutaneous system in the neighboiu-hood of the nose which we have seen to be characteristic of the Ehinolophidfe and Megadei-ms, and no doubt subserves the same purpose in the economy of the animal as the external nasal appendages of those Bats. The ears are large, and united across the forehead by a sort of membranous band; the tail is.
