The fringe-lipped bat is large, dark-colored, and has large peculiar condition of the lips and chin have been describedunder the genus. The forearm measures about Fig. 9.—Trachops 174884, U. S. Nat. Mus. About nat. size. A specimen of this species was taken by August Busck in theChilibrillo cave near Alhajuela, in March, 1912. Specimens examined: Rio Chilibrillo (Chilibrillo cave), I. Genus VAMPYRUS Leach Very large general size, the forearm over 100 millimeters orfour and one-fourth inches long and wing expanse about 760 milli-meters or two and one-half feet, alone distinguishes the genusVampyrus among American bats. The ears are long, relativelynarrow and round-pointed, and the interfemoral membrane is large,but there is no external tail. In the form of the braiucase the skullclosely resembles that of Phyllostomus, but the sagittal crest is muchhigher and projects farther posteriorly; the rostrum and mandibleare much longer; the latter affording space for an additional pre-molar; the nasal opening is slightly extended backward by a V-shaped emargination. Dental peculiarities are numerous
