. Catalogue of the mammals of western Europe (Europe exclusive of Russia) in the collection of the British Museum. 247 I. Nyctalus noctiUa. Nat. size. the region on each side of it flat or sHghtly depressed ; lambdoid crest high, curved abruptly forward at point of junction with sagittal crest; floor of brain-case with small but evident lateral pits, well defined anteriorly but communicating posteriorly with vacuity between cochlea and basioccipital; auditory bulhe well developed but of moderate size, the transverse diameter al>out equal to distance between bulhe. Interorbital region deeply constricted, short hour-glass shaped, the lachiymal region widen- ing abruptly to a breadth nearly equal to that of brain-case, and forming a slight though evident tuber- cular projection over anterior rim of orbit; rostrum squarish, somewhat narrower anteriorly than posteriorly, the oval or ovate narial emargination extending back to level of lachrymal foramen; rostral depth at front of orbit about equal to distance from orbit to front of inner incisor ; anteorbital foramen small, over space between large jiremolar and first molai', lachrymal foramen slightly above and behind it, on orbital rim. Palate rather short, owing to the large size of the anterior emargination, the posterior edge of which is on level with middle of large premolar, rather evidently concave laterally, less so longitudinally. Posterior extension of palate nearly parallel sided, its width at level of posterior edge of third molar slightly less than length ; hamulars barely turned inward ; median spine large, acute. Mandible robust, noticeably deeper at symphysis than immediately behind tooth-row; posterior portion rather low and long, the height of coronoid process above alveolus less than least length, the upper border sloping gradually from coronoid to articular jsrocess ; angular process moderately long, about on level with alveolar line, its main axis directed rather abruptly outward, its distal extre
