The generic name of this bat is composed of two Singhalese words— 
kehel or kela, the plantain, and vowlha, which is the Singhalese for bat, 
the specimen on which Gray founded his genus being the following :—

The Painted Bat (Terdon’s No. 53). 
Hapitat.—India generally, Burmah and Ceylon. 
DESCRIPTION—“ Fur fine, woolly ; above yellowish-red or golden
