A. Old- World Species ■[. 

 a. Tragus attenuated above, acutely pointed, 

 and curved outwards. 



* The two species contained in this section would, perhaps, be more correctly 

 classed with those of the next section, where they should occupy a place next 

 V. mystacinits, to which they are closely related ; but the comparatively large 

 size of the feet and projecting caudal vertebrae render their position here 

 necessary in order to fall in with the general plan of arrangement of the species.
