o CL e • PC I Fig. 1 Projections of rostra of small Myotis onto the first two principal components (PC I« 34.1%, PC II» 12.0%). + - M. paradaubentoni sp. n.

, • * M. helleri, all are from Osztramos Localities 9 and 13. Arrows indicate holotypes and important specimens (see text and photos) ture with narrow interorbital constriction (Plate II, Fig. 1) and a strong dorsal concavity in lateral view (Plate II, Fig. 3) which means that it was strongly bent to the braincase. The rostrum is definitely smaller than that of M. emarginatus

, but with resemblance to that. It possesses a wider anteorbital bridge and less well-defined flatness at the sides and just behind the narial notch. The canines of helleri are smaller, and with rounded basal cross-section not pressed laterally as in emarginatus

. Its small premolars are rather loosely set, subequal in size and smaller than those of emarginatus

, but also not so contrasted in size. The strongly and antero-posteriorly elongated P

4 is sometimes without any trace of antero-internal cusp as in the recent species. The M* and M

2 are with more rounded lingual margin than those in emarginatus

, although both species have very weak hypoconuli. The paraconuli (protoconuli) of the molars are weak (in M and M

2

) and medium (in M

3

). Medium weak postprotocrista-premetaconule wing (see: VAN VALEN 1966, p. 8) exists but there is no sign of centrocrista, the same situation as in emarginatus

. M

3 is anteroposterior^ shortened but less so than in emarginatus

.
