Length, from snout to tail-tip, 3 to 3I inches (76 to 89 

 mm.); forearm, from elbow to wrist, if to if (35 to 41 mm.); 

 tibia, 1% to ii (14 to 17 mm.);

In colour it is everywhere of

In discussing a highly col- 

 oured phase of the British Bar- 

 bastelle, Sir Harry Johnston says:^ 

 "In some other Vespertilionid 

 Bats there is a tendency in the 

 breeding season for the males to 

 develop a rich yellow tinge in the 

 lower half of the hair of the un- i^" 

 der parts. It may be the same ten- 

 dency which tinged the fur of this 

 example with a purplish tone." 



This species closely resem- 

 bles M. subulatus, but may be 

 distinguished by its shorter ears, 

 which do not reach to the end of 

 the nose (instead of considerably 

 over), and by its shorter, more ^"* 

 rounded tragus (see Fig. 264.).
