Description. — The edges of the lower incisors are parallel 

 to the jaw, so that these teeth touch at the sides only, and 

 do not overlap each other. The first upper incisor is forked, 

 nearly half as long as the canines, and scarcely higher than 

 the second incisor, with its second division leaning outwards, 

 and almost as long as the first division ; the canines are 

 strong, the upper slightly longer than the lower, which 

 latter are longer than the grinders ; the outer margin of 

 the ear ends below and behind the angle of the gape ; the 

 inner margin is as long as the breadth of the ear, giving it 

 the appearance of an equilateral triangle; the space be- 

 tween the ears is greater than that from the nose to the 

 ear ; the snout is short and blunt, its outline nearly semi- 

 circular ; the wings are rusty black, near, and along the 

 hind legs, thickly clothed with hair on the upper surface. 

 Fur on the upper parts of the body dull red-brown, on the 

 parts beneath dull greyish yellow, approaching to rusty 

 near the wings ; the hairs everywhere, for three-fourths of 

 their length, are brownish black, with their extremities of 

 lighter shades; from the shoulders, passing beneath the 

 ear and along the lower jaw on each side, is a brown streak 

 of a darker shade than the parte adjoining. 



Length of head and body, 1 inch 10 lines ; tail, 1 inch 

 3 lines ; extent of wing, 8 inches 10 lines. 



This Bat has been observed at Berlin, Halle, in Brims-
