Interorbital width hard to determine, as no postorbital processes visible. Foramen infraorbitale situated rostrad (within the anterior eighth of the total skull length, above the first upper premolar).. : Choeroniscus godmani skull, a: lateral view, b: dorsal view, c: basal view Skull base with conspicously elongated rectangular palate surface (width over canini equals width over molars), roof of the palate almost reaching the Fossae mandibulares. Pterygoids form long, shovel-like widened processes coming in contact with the tympanohyoid bones at the bullae. Presphenoid smoothly adjoining the well vaulted basisphenoid. Contiguous ridge between presphenoid and basioccipitale comparatively broad, prolonged in two wings curving around the Foramen occipitale. Teeth: dental formula - 2 3 1 - - 3 4 5 6 7 - - - 1 - 2 3 4 5 6 7 Upper incisors very small, the outer ones being double the size of the iimer ones, separated by a large medial diastema, very different in form: is flat, with stamp-shaped crown and definitely tiny. I" almost caniniform, but though of twice the size of so small that it does not match the height of the cingulum of the C\ Canines deUcate and narrow with cingulum, length less than height of the maxillare at tliis level of the rostrum, seperated from the anterior premolar (P^; Miller 1907) by a large diastema. Premolars tricuspid, the middle conus being the highest, slightly exceeding cingulum C^ Base in basal view elongated and narrow. Molars
