Skull of Surdisorex schlitleri n. sp. (FMNH lateral view. 95069, holotypc); cranium in lateral, dorsal and ventral view, mandible in members of the genus, and almost in contact with the an- terior edge of M'. Lower P4 narrow. Mandibular condyle heavy and straight-sided, forming a near-triangle without sinuosity. Description. The new species exhibits characters typical for the genus. The tail is short ( of Head and Body). Fur is thick and woolly, length of single hairs on dorsum 9 mm. Color faded, presumably because of long- term preservation in alcohol, base of hairs dark brown, ter- minal 2 mm lighter. The foreclaws greatly enlarged, hind- claws moderately so (Fig. 2). Ear conch absent. Eyes re- duced and covered in membrane. Skull hexagonal, typi- cal of burrowing Soricidae ( Myosorex, Anourosorex, Blarina) with particularly well-defined anterior facets of the braincase (Fig. 3). Interorbital region elongate (be- tween posterior processes of maxilla and anterior aspect of the braincase). Bridge across infraorbital foramen nar- row ( mm). Nuchal crests well-developed, sagittal crest slight. Braincase small and short, as reflected in the measurement from the anteromost comer of the braincase to the corresponding occipital condyle and in the distance of the antero-lateral component of the hexagon-shaped braincase. Foramen magnum oval-shaped. Paired frontal foramina within interorbital basin. This basin provides a sinuous curve to the lateral profile of the skull. Protocone of P'* very prominent, forming a prominent shelf with parastyle. Upper M' and M- without metaloph. Low- er incisor denticulate, with chisel-like tip. Mental foramen beneath second cusp of lower P3. Lower P4 fairly nan ow, exhibifing the inverted v-shape pattern typical of the Myosoricinae (Hutterer et al. 2
