Catalogue of the mammals of western Europe (Europe exclusive of Russia) in the collection of the British Museum. 280 CHIROPTERA temporal fossa at sauie level, its length about twice width; hamulars small and inconspicuous. Mandible long and straight, its axis scarcely bent upward posteriorly ; symphysis deep, scarcely or not subtended by a concavity in lower border of ramus ; posterior portion of mandible low, the depth through coronoid process barely equal to distance from front of coronoid to back of condyle ; angular process large, straight, directed backward, outward and downward.

. Catalogue of the mammals of western Europe (Europe exclusive of Russia) in the collection of the British Museum. 280 CHIROPTERA temporal fossa at sauie level, its length about twice width; hamulars small and inconspicuous. Mandible long and straight, its axis scarcely bent upward posteriorly ; symphysis deep, scarcely or not subtended by a concavity in lower border of ramus ; posterior portion of mandible low, the depth through coronoid process barely equal to distance from front of coronoid to back of condyle ; angular process large, straight, directed backward, outward and downward. Teeth.âRelatively to size of skidl the teeth are rather large, the lower molars in particular. The most obvious peculiarities of the dentition as compared with that of other European bats are the single, well developed incisor in each side of upper jaw, and the presence oi a large hypocone, quite distinct from commissure of jarotocone, in i«' and wi". Upper incisor simple, a little moi'o than half as high as canine, the shaft set at an angle so that the points of the two teeth are much nearer together than their bases ; cingulum faintly indicated in front, better developed and forming an incipient cusp postero-externally ; posterior surface of shaft somewhat flattened; space between incisor and canine aljout equal to greatest diameter of smaller tooth. Lower incisors three on each side, much imbricated and closely crowded in narrow space at front of canines, their cutting edge barely rising to level â of canine cingulum. The inner and middle tooth sub-equal, rather deeplj' bifid, the outer barely equal to outer lobe of the others, its apex faintly notched. Upper canine moderately large, its crown area somewhat more than double that of upper incisor, the general outline of its base an irregular triangle with its longest side directed inward, and with the postero-external side slightly concave; cingulum narrow but well developed throughout, not tending to develop small cusps
