In one of the next succeeding Numbers of these Researches, I propose to exhibit 

 a connected view of the various Chiroptera which I have observed in Java. A large 

 proportion of these has not previously been examined or described. Of the Genus 

 Pteropus, four species have been arranged at the Museum of the Honourable East 

 India Company ; two of these belong to the first, and two to the second subdivision 

 of the Genus : the former comprises those that are entirely without tails ; the latter 

 those that are provided with short tails.
