13. Vespertilio davidii. 



Vespertilio davidii, Peters, 3IB. Akad. Berl. 1869, p. 402 ; Bobson, 

 Monogr. Asiat. C/m-opt. p. 132 (1876). 



Mnzzle aud ears as in V. dauhentoiui ; laid forwards the extremity 

 of the ear extends exactly to the end of the muzzle ; the outer mar- 

 gin of the ear-conch terminates in a small distinct round lobe. 

 Tragus long, subacute, attenuated in upper third ; inner margin 

 straight, lower two thirds of outer margin convex, ujoper one third 

 straight ; a distinct lobule at the base. 



Wings from the base of the toes ; feet rather large ; toes nearly 

 equal in length ; last two caudal vertebrae free ; the calcaneum ex- 

 tends somewhat more than half the distance between the ankle and 

 the tail. 



Fur, above, dark, with light-brown tips ; beneath, similar, with 

 grey or ashy extremities. Above and beneath, the wing- and inter- 

 femoral membranes are covered along the sides of the body only. 



The second upper premolar is very small, and jJaced internally 

 in the angle between the closely approximated first and third pre- 

 molars ; in the lower jaw the second premolar is also very small and 

 internal, but the first and third premolars are separated by a small 

 interval. 



This species is very like V. dauhentonii ; but the outer margin of 

 the ear is less concave in its upper half, and the lower half is less 

 convex ; it is also distinguished by the position of the second pre- 

 molar (which, as described above, is internal to the tooth-row in 

 both jaws), by the projecting caudal vertebrae, and by the attach- 

 ment of the wing-membrane, which extends qmte to the base of 

 the toes.

13. Vespertilio bocagii. 



Vespertilio bocagii, Peters, Jorn. de Sci. Math.-Phys. e Nat. Lishoa, 

 1870, no. 10. 



The crown of the head is slightly, but rather abruptly, elevated 

 above the face-line, the muzzle rather short, and the glandular pro- 

 minences small. Ears shorter than the head, laid forward the tips 

 extend exactly to the end of the nose ; in general shape very similar 

 to those of V. mystacinns, but the tip is more directed outwards and 

 the lower half of the outer margin less convex. The tragus is also 

 like that of T". mystacinus, but is proportionately shorter, narrower, 

 and more acutelj' pointed, and the lobe at the base of the outer 

 margin is triangular, not rounded (Plate XVIII. fig. 6, ear, double 

 natural size ; tragus rather too broad).
