Catalogue of the mammals of western Europe (Europe exclusive of Russia) in the collection of the British Museum. 228 CHIEOPTERA SJcuH.—General aspect of skull robust and flattened, with widely spreading zygomata, but rather narrow brain-case and rostrum. Dorsal prolile rising gradually from nares to over- hanging lambda, essentially straight throughout, though with slight concavity over lachrymal region. Ventral profile very slightly elevated posteriorly. Brain-case ovate in general outline, narrower than in Ni/ctahis noctula, the straight, well developed lambdoid crests which form its posterior border meeting in median line almost at right angles, depth at middle about half mastoid breadth ; sagittal crest low but evident, the region at each side of it not depressed ; floor of brain-case smooth, with no evident ridges or depressions, a very narrow slit between cochlea and basioccipital ; auditory bulhe small, the transverse diameter con- siderably less than distance between bulla?. Interorbital region moderately constricted, hour-glass shaped, the lachrymal region decidedly less wide than brain-case, with slight tubercular projection close to anterior rim of orbit; rostrum flattened, with shallow but evident lateral concavity on each side, dis- tinctly narrower anteriorly than pos- teriorly, the narrowly obovate narial emargination extending about half way back to level of lachi'ymal fora- men ; rostral depth at front of orbit less than distance from orbit to outer incisor ; anteorbital foramen less re- duced than in Ni/ctalus noctula, its posterior border over region of con- tact between large premolar and first molar, lachrymal foramen directly behind it, on inner side of orbital rim. Palate long and narrow, slightly concave both laterally and longitudinally, the anterior emargination small, squarish, extend- ing back to level of middle of canine. Posterior extension of palate nearly parallel sided, though narrowing a little posteriorly, its width at level of
