42 Notes on an Australian Bat. 



evening in his study. He asked me to examine the nocturnal 

 visitor, and to see whether it would turn out to belong to 

 that species of which I had the honor to lay a specimen be- 

 fore you on a former occasion, or to be not related to it. 



Although it is related to the one alluded to, it differs in 

 so many essential points from it, as to stamp it at once as 

 belonging to another species of the same family. I received 

 the Bat on April 11th, and it lived for five days longer, during 

 which time it refused to take any kind of food. Notwith- 

 standing the weather being not at all cold, and the animal 

 apparently unhurt, it scarcely moved about ; it was fat, and 

 of a less lively temper than Eat No. 1. (See "Transactions" 

 for 1858.) 



Colour: head and back, dull chestnut-brown; a little 

 lighter on the sides and belly, and more so on the root of 

 tail ; muzzle and chin, dark broAvn ; lips, black ; ears, nearly 

 black ; wings, brownish-black; hair, lower part, black (on 

 the back), and brown (on head and belly) to the extent of f 

 of the whole length of hair, which is ^ of an inch long ; a 

 small brush of black hair over the eyes ; very fine, but not 

 many bristles round the muzzle ; the membranes are void of 

 hair, except on the under side, where they extend from the 

 sides towards the elbows in a thin layer of a very light brown- 

 ish colour, and hence to the wrist, along the lower arm, in 

 about 15 narrow, nearly parallel rows of very short hairs ; the 

 same is also observed from the root towards the end of the tail. 

 The back of the ears is completely covered with hair, while 

 the front shows only the bare skin. In front of the eyes 

 there is a naked spot on each side of the muzzle. Fur, fine 

 and silky. Dimensions : length, from tip of nose to root of 

 tail, 2 inches; tail, If -inch; ears, a little above ^-inch; ex- 

 pansion of wings, 10^-inches; length of forearm, exactly H- 

 inch; the hind-foot is y s -inch long, and the fingers all of an 

 equal size, and their back covered with minute hairs. The 

 talon stretches far towards the tail, which does not extend 

 outside its membrane. The specimen under examination is 

 a female, and although a young one, it is full grown, offering 

 the benefit of a good examination of yet unworn teeth. The 

 dentition is as follows : — ■

The general arrangement and form of the teeth are very 

 like as in Bat No. 1, with the exception that the lower inci-
