it appears quite distinct in form from any of the Horse-shoe Bats I 
have hitherto observed. 
This species appears to be quite distinct from Hipposideros 
speoris of Timor, which is described as being a little larger than the 
larger English Horse-shoe Bat, Phyllorhina bifer ; it has the follow- 
ing synonyma :—
