Order II. — Chiroptera. 



Such great strides have been made in the classification of the 

 liats since Blanford published his " Mammalia," that I have found 

 it necessary to go into the currentlj^ accepted distribution, not 

 only as it affects the genera, but the Families and Suljfamilies. 

 The most recent works are ]\Iiller's " Families and Genera of 

 Bats," 1908, and K. Andersen's " Catalogue of the Chiroptera," 

 Vol. I. (Fru.it Bats), 1912. Both these, it will be seen, were 

 published before Svirvey specimens were available. I have follow- 

 ed as closely as possible the two works quoted above, so far as they 

 deal with the Indian fauna, ri.-:., Miller for the general classifi- 

 cation and Andersen for the MEGACHiRorTERA. The Families may 

 be arranged in a key as follows : —
