. Bonner zoologische Monographien. Zoology. 58 visible in X-ray examination. Palate elongate, in basal view rectangular, similar to C. godmani, but considerably larger.. Fig.44: Choeroniscus minor, a: skull basal view, b: skull dorsal view, c: mandible top view, d: skull lateral view Skull base characterized by conspicously elongate pterygoid processes (hamuli), together with the tympanohyoideum reaching below the Bullae tympanicae. hi connection with the alisphenoid they cover the vomer as weh as one third of the presphenoid. Basisphenoid distinctly structured, with ridge development towards the basioccipitale, the latter parting into two wings which flank the Foramen magnum. Orbitae without distinguishable orbital processes - thus, in most cases, the interorbital width ist no distinguishable measure from the postorbital width. Palatal level elevated against skiill base, in lateral view, the rostrum appears very straight. The contours of the braincase well vaulted, but without distinct indentation. Mandibula elongate and narrow, lower mcisivi missing - a median V-shaped notch between the canini, allowing the long tongue to pass without openmg the mandible joint. Mentum with weU developed symphyseal ridge; Proc. coronoideus flattened, merely projecting beyond the Proc. articularis. Angular process forms the proximal mandibular edge. Teetli: dental formula - 2 3 1 - - 3 4 5 6 7 - - - 1 - 2 3 4 5 6 7 Teeth very delicate showing wide gaps between individual premolars and molars. Premolars and molars tricuspid in lateral view lacking relevant masticatory surfaces, hicisivi only present in the upper jaw, very small, the outer ones exceeding the inner ones in size and grouped in two pairs by a wide medial gap. Canini thin and pointed with cingulum, premolars separated from the canini by distinctly developed diastema. Elongate, narrow base (without masticatory surface), protoconus about 3/4 the height of the cingulum of the canini, metaconus liigher tlian cingulum. C. inte
