much smaller than the continental example; besides, the extreme tip of 

 tail is not free. Also of these three bats the following words of Dob - 

 son hold good (1. c. p. 183) ,,. . . Vesperugo annectens agrees so remark- 

 ably in general form with the species of Vespertilio that it can only

be distinguished by its dental characters''. They have pm , and I 



can not find that they show any other characteristic difference from the 

 genus Myotis. 



Comparing the skull with those of a Myotis and a Pipistrellus we 

 find that the crown of the head is slightly raised above the face-line 

 as in Myotis and not flat and broad as in Pipistrellus^ which appears 

 from the fig. 1 — 3. 



The muzzle is pointed as in Myotis^ not obtuse as in Pipistrellus. 



The ear and the tragus do not differ from those of the genus 

 Myotis; in regard to their shape I refer to the figure 96 in Blanf ord's 

 Fauna of British India. 



They have no postcalcaneal lobe, agreeing in this respect with most 

 species of Myotis. 



The genus Pipistrellus is generally said to be characterized by short 

 legs. To find out if this is true also with regard to Pipistrellus annectens 

 and if the genus Pipistfellus in general has shorter legs than the genus 

 Myotis, I have compared the length of head and body with that of the 

 tibia in specimens belonging to several species of Myotis and Pipistrel- 

 lus^ using the measures given by Dob son as well as measures taken 

 by myself. I have found the following proportions :
