faintly, if at all, so marked ; and instead of the small tufts of bristle- 

 like hairs about tbe eyes, the present species 1ms a tolerably regular 

 series of similar ones fringing the eyelids. Again, the cranium has 

 so strongly marked a sagittal crest as to be easily detected in the 

 mounted specimens, whereas in AT. Qeqffroyi it is so feebly developed 

 thai no trace can be discovered, unless the skull be extracted and 

 carefully cleaned. 



Bnt the great difference in the size of the two animals is alone 

 sufficient to distinguish them, the one being only!) inches in expanse 

 of wings, whilst the other attains fully 13 inches; nearly as great a 

 difference as exists between the Pipiatrelle and the NoctuU Hats. 



The fur of the upper parts is bicoloured, nearly black at the base, 

 with the terminal half dark sepia-brown ; that on the top of the head 

 and on the membrane uniting the ears, unicoloured, and paler. 



Beneath, the fur has the basal half nearly black, the remainder 

 being light brown, palest on the throat, on the middle of the belly, 

 and on the pubes. On the shoulder of one example from " Perth, 

 Western Australia," is a patch of brownish rust colour, but it does 

 not occur in the other examples. 



Although the original specimen of this species is reported to have 

 been received from Timor, I am inclined to believe that there may have 

 been some mistake respecting its locality. Among a great number of 

 Bats from that island contained in our museums and that of Lcyden, 

 representatives of this genus do not appear ; but specimens absolutclv 

 identical with the original in the Paris collection have been obtained 

 by Mr. Gould in Western Australia ; and I have noted one in the 

 Leyden Museum, also from Australia, but without any precise in- 

 dication of locality. 



The following dimensions have been taken from specimens col- 

 lected by Mr. Gould, the first being the one from Perth, Western 

 Australia : —
