This bat is common about Calcutta, frequenting ruins, dark places 
and hollow trees. It is allied to M ‘tenuis (Horsfield), and it is men- 
tioned as inhabiting hollow trees in such numbers as to attract attention 
by the hissing noise from within, every available spot in the interior 
being occupied. A synonym of the genus is Dysofes.

Hapirat.—India generally. 
DEscriPpTION.—This differs from the last in having the wing mem- 
brane from the ankles, and in the free portion of the tail being shorter ; 
ears united at the base; tragus broad and rounded above, partially 
concealed by the large anti-tragus. 
$1zE.— About the same as the last.
