    as .and hy the oval elongated ear and narrow attenmited tragus. In the British Isles this genus is represented ]jy four species, viz. Bechstein's Bat (V. heclisteini); the Eeddish-Gray Bat (V. nattereri), of very local occurrence ; Daubenton's Bat (V. dauhentoni); and the AVhiskcred Bat (F. mystaciimsi). Cerivoula}—This genus, which has the same dental formula Vespertilio, is distinguished by the parallel upper incisors, and the comparatively large size of the second upper premolar. Some ten species have been described from the Ethiopian and Oriental regions, of which C. pida, from India and the Indo-Malayan subregion, is the best-known, being well characterised by its brilliantly coloured orange fur and conspicuously marked membranes, which are variegated mth orange and black. This genus includes the most deli- cately formed and most truly insectivorous, tropical, forest-haunting Bats, which appear to stand as regards the species of Vespertilio in a position similar to that occupied by Chalinolobus vnth respect to Vesperugo. The Miniopterine division includes only two genera, and is characterised by the great eleva- tion of the crown of the head above the facial line, and by the upper incisors being separated from the canine and also in the middle line. Natalibs?—This genus, while having the divisional characters mentioned above, agrees in the dental formula and its general external form with Cerivoxola, from which it is distinguished by the short triangular tragus. It in- cludes three species, restricted to South and Central America and the West Indies; the head of N. micropiis being shown in Fig. 310. Miniopterus.^—Dentition : i f, c ^, f, m -f; total 36. In addition to the difference in the number of the teeth, this genus is distinguished by the shortness of the first phalanx of the middle finger and the great length of the tail, which is wholly contained within the interfemoral membrane; it includes four species, restricted to the eastern hemisphere.
