Wissensch., Berlin p. 475, plate opposite p. 480. Type-species.—Saccopteryx brevirostris Wagner. Geographic distribution.—Brazil. Number of forms.—The type is the only known species. Characters.—Skull as in Saccopteryx, but rostrum shorter; depth through lachrymal region greater; rims of orbits more widely ex- panded, palatal emargination extending back to level of small pre- molar; and interpterygoid fossa nearly parallel-sided, slightly con- stricted near middle, its anterior termination broad and encroached on by evident median palatal projection. Teeth not essentially dif- ferent from those of Saccopteryx. Position of wing sac not known. Species examined.—The characters of Cormura are known from Peter's description and plate only. Remarks.—Though apparently a near ally to Saccopteryx, this genus is readily distinguishable by the structure of the interpterygoid region. Genus PEROPTERTX Peters. 1867.
