Show 1 9 0 5 .] OF THE GENUS RHINOLOPHUS. 1 1 3 which has preserved the tail of the eastern races (cf. also its geographical habitat); the horse-shoe is remarkably narrow. The skull very small and slender ; the nasal swellings narrow. (2) Compared with obscurus: Larger, but 'proportionately with narrower horse-shoe. The skull is even smaller and more slender than in any individual of obscurus I have seen. (3) Compared with the eastern races: The small size, combined with the very small horse-shoe, distinguishes it sufficiently. The skull is smaller and, especially, more slender, the nasal swellings narrower, than in any of the eastern forms. Dentition (one skull). p3 and p2 present. Cingula of the upper canine and p1 overlapping. This dentition is more in accordance with that of the typical ferrum-equinum than that of regulus, showing the " western " character of proximus (notwithstanding the short tail), a conclusion borne out by the general external aspect of this Bat, and the size of the skull and the tooth-rows.

Diagnosis. Size moderate, horse-shoe rather narrow, tail long. Skull rather small and slender, with narrow nasal swellings and short tooth-rows. * Koch's two " varieties " of ferrum-equinum must have been based on too small a material, or there must be some mistake in his statements. That individuals from S. Europe, i. e., Europe S. of the Alps (his " var. italicus"), should, generally speaking, be larger than those from Europe N. of the Alps (his " var. germanicus "), is at all events not correct. The statement that var. germanicus is " liber den Riicken mehr braungrau oder aschgrau gefarbt," whereas var. italicus " stets in das Rothliche neigt," raises the suspicion whether Koch has not compared immature individuals from Germany with fully adults from Italy.
