Remarks.—While examining the bats in the Royal Museum of Nat- ural History in Berlin I found four specimens from Surinam col- lected by Kappler and labeled by Peters as Oormura brevirostris. Cm comparison with the original description and figure of this genus," however, striking discrepancies were at once apparent. An- other specimen of the same animal, from Baranciva, Brazil, was sent me by Dr. Lorenz von Liburnau, of Vienna, with the informa- tion that the type of Oormura, originally in the Natural History Museum, could no longer be found. The genus Cormura therefore rests wholly on the plate and description; and as these do not agree with the specimens it was necessary to name the animal represented in the museums of Vienna and Berlin. This genus is well character- ized by the complete absence of hypo- cones in the upper molars and by the great reduction of the upper incisors. In the four adults examined the upper incisors are absent. In an immature individual, however, there are two very minute teeth in each premaxil- lary. Whether this condition is nor- mal can only be conjectured, but neither tooth has the appearance of a remnant of the milk dentition, no trace of which can be found elsewhere. In the description of Cormura the upper incisors are merely said to be extremely small, while the figure shows them of normal size for members of the group. No mention is made of the hypocones of the upper molars, but these cusps are unmistakably indicated in the plate. Genus BALANTIOPTERYX Peters. 1867. Balantiopteryx Peters, Monatsber. k. preuss. Akad.
