This bat is found in great abundance in and about 

 Kandy. I have several fine specimens from the Kurunegala 

 tunnel, which swarms with them. This is the largest of 

 all horse-shoe bats hitherto seen in Ceylon. I have ven- 

 tured to consider it new, as it is not to be found in Mr, 

 Blythe's Monograph of Indian Bats.
