^ In my note-book I find the following obserration regarding this species: — 



"August 23rd, 1869. — This species has been flying for the last few days from 

 the north to the south of the city, in immense numbers, immediately after sun- 

 down. The sky, from east to west, has been covered with them as far as the 

 eye could reach, and all were flying, with an evident purpose, and making for 

 some common feeding ground. Over a transverse area of 250 yards, as many as 

 70 bats passed overhead in one minute, and as they were spread over an area 

 of great breadth and could be detected in the sky on both sides as far as 

 could be seen, their numbers were very great, but yet they continued to pass 

 overhead for about half an hour. This is not the first time I have observed 

 this habit in this species ; indeed, it was (auch more markedly seen in August 

 1864, while I was residing in the Botanical Gardens, Calcutta. The sky, 

 immediately after sunset, was covered with this bat, travelling in a, steady 

 manner from west to east, and spread over a great expanse, all evidently 

 making for one common goal, and travelling, as it were, like birds of passage 

 with a steady purpose. I observed them, not only on one, but both sides of the 

 river. But in the Botanical Garden I noticed that, whilst the great ma'is of 

 bats passed on, a few were attracted by trees then in fruit and seemed to go 

 no further. This continued for a number of successive nights, but I did not 

 observe the bats rt'turning."
