In addition to the generic characters given in the preceding 

 article, this Bat has very obvious and specific features that 

 make it easy to identify. 



In size it exceeds all others in our list. Total length, 5 to size 

 5^ inches (127 to 140 mm.); tail, 2 to 2| inches (51 to 60 mm.); 

 forearm, i| to 2| inches (45 to 57 mm.); tibia, | to i inch (22 to 

 25 mm.); spread, 15 to 17 inches (381 to 432 mm.). 



In style of colour it approaches the Red-bat. The fur colour 

 next the body is dull blackish, but this does not ordinarily 

 show; the general under-colour visible is a soft sienna or orange 

 buff, much grayer on breast and belly; but on the chest and 

 upper parts each hair has a dark-brown zone, and, finally, a 

 silvery-white tip; the general effect is rich, deep brown, exqui- 

 sitely frosted over with white; the chin is clear pale brown or 

 yellow; the ears have black rims, and the muzzle is more or less 

 black. 



When in air, this species may be distinguished from all by 

 its long, pointed wings, great size, and swift zigzag flight.
