ANNALES MUSEI NATIONALIS UUNGARtCI. 1924. A NEW VOLE FROM HUNGARY AND AN INTERESTING BAT NEW T6 THE HUNOARIAN PAUNA. By Dr. J. EHIK. Pitymys transsylvanicus n. sp. Type locality. — Mts. Fogaras near Kercz (County Fogaras) around the Bulea Lake, allitude 2046 m. Gco/jraphicai distribution. — Known only froni the type locality. Diaynosis. — Size small, hind foot about 13*5 mm., condylobasal lengtb of skull 20 mm. The smallest known European species. Skull small, intcrorbital region relalively wide ; the anterior parts of the skull from the posterior border of interorbital constriction relatively short to the length of the brain case (8*5 : 11*7). The depth of the brain case including auditory hullae is vcry great (7*4 mm.). Colour. — Upper parts not vivid dark reddish brown, with very many black hairtips; basal portion of hairs dark slate-black. Underparts pale smoke-grey, nearly white; the lighter slaty bases of the hairs everywhere shownng through at surface. Feet dusky grey. Tail sharply bicolour, dark browm above, light whitish grey benealh. Skull. — The skull is small and sniooth, with large brain case. The anterior parts of the skull from posterior border of interorbital constriction relatively short to the length of brain casc. . v ininmm transverse diameter of interorbital region 3'7 mm.; transverse diameter of anterior parts of rostrum 3"5 mm.; its upper transverse diameter hetw r een anleorbital foramens, close before Proc. zygomaticus maxillaris 3*1 mm. Dorsal profile straight from the point, above anterior border of anteorbital foramen to brain case ; from posterior margin of interorbital constriction markedly convex beyond posterior margin of interparietal, beyond which the occiput curves downward without noticeable angle. Nasals sloping forw^ard at an angle of about 15°. The general outline of skull as viewed from the side, narrowly cuneate ; the depth of brain case including auditory bullae is very great (7'4 mm.); orbital depth beyond incisors 3*2 mm. Brain case from back of interorbital constriction as long as zygomatic breadth; its surface smooth, lambdoid crests only developed slightly at sides. The depth of the brain case through auditory bullae about 70 per cent of occipital breadth. Occipul ronndcd off behind; paroccipital proccsses slcnder, their tips
