1959 XXVII-Ch4, the right C sup. 0.78 × 0.63 × 1.30.

D e s c r i p t i o n. A tiny upper canine with damaged anterolinual part. The crown is evidently triangular in crosssection, shaped by a well-developed cingulum, and shows distinct posterior and lingual crests. The buccal crest is weak, but visible. The posterobuccal face is slightly concave. The posterolingual concavity is wide; the lingual cingulum forms a weak but noticeable lingual talon.

C o m p a r i s o n. It is obviously a canine of a vespertilionid bat, exhibiting both in size and morphology characters of the genus Miostrellus (triangular occlusal outline, concave posterobuccal face). It is smaller than M. risgoviensis ( Rachl 1983: 226, tab. 52) and smaller than specimens BSP 1959 XXVII-Ch7-8, but falls into the variation range of M. risgoviensis.
