HAVING in the former Numbers of this Work described and figured various 
subjects of the Family of Chiroptera, I have proposed in the present to give a 
connected view of tlic species collected in Java, which belong to the genus 
Vespertilio, as defined by M. Geoffroy St. Hilaire, with a more detailed account of 
one of these, which is represented on the Plate annexed to this article. I have 
dedicated it to my illustrious friend, C. F. Temminck, the Director of the Museum 
of Natural History of the King of the Netherlands, in Leyden. 
The species will be enumerated in the following order : — 1. Vespertilio Tern- 
mincMi; 2. Vespertilio adversus ; 3. Vespertilio Hardimchii; 4. Vespertilio tralatitius ; 
5. Vespertilio imbricatns; 6. Vespertilio pictus.
