they represent a valid lighter-coloured Eastern subspecies, for 
which there appear to be several names available.

No. 5.10.4.13. Type. 
A very small species. The minute upper premolar in the 
tooth-row. 
Size about as in P. nanus and mimus. Ears of medium size; 
inner margin slightly convex, outer margin with a well-marked 
concavity in its middle third; antitragal notch shallow, the outer 
basal lobe low, buried in the fur. Tragus of medium length, 
rather broad, its broadest point just above its inner base; inner 
margin slightly concave; outer basal lobe rounded. Wings to the 
base of the toe. 
General colour above ‘“ wood-brown,” the hidden basal halves 
of the hairs blackish. Under surface similar, but rather lighter. 
Ears and wing-membranes blackish grey, the hinder edge of the 
wing from the tip of the fifth finger backwards prominently 
white, as in P. kwhlit. 
Skull small, delicate; much as in P. nanus. Outer upper 
incisors about equalling the well-marked secondary cusp of the 
inner. Large premolar well separated from the canine, the small 
premolar standing in the tooth-row, wholly visible from without. 
Dimensions of the type :— 
Forearm 31 mm. 
Head and body (in flesh) 41; tail 35; ear 10. 
Skull—greatest length 11:3; basal length in- middle line 8:7; 
breadth of brain-case 6:1; palatal length 4; combined length of 
large upper premolar and two molars 2°8; lower tooth-row from 
front of canine 4:2. 
Hab. and Type as above. 
This little Bat is perhaps a representative of the Indian 
P. mimus Wrought.*, with which it agrees in size and certain 
other characters. But it is much lighter in colour, the extreme 
tips of the dorsal hairs m that animal being alone pale brown, 
the rest being blackish, and the small upper premolar does not 
stand so well in the tooth-row, although more so than in most 
species of the genus. P. nanus again is a dark-coloured bat, as 
dark as a European Pipistrelle.
