the South Australian spechnen, those in column 2 of the one from 

 Van Diemen's Land, whilst those in the 3rd have been taken from a 

 specimen of S. greyii from Port Essington (one of the types in the 

 National Collection), and are added to show the difference in the 

 size of the two species, — S. greyii being the only Australian bat ap- 

 pertaining to this restricted group which approaches in size the 

 species here described.

The teeth of this species, although not suflficiently examined to 

 furnish a comparative description, are nevertheless seen at a glance 

 to be of very small size, not only in reference to the size of the ani- 

 mal, but also actually smaller than those of several other species of 

 much less size, such as S. trilatitius, S. lobatus, and S. qbramis. 

 Hence the specific name of microdon here bestowed upon it. 



2. SCOTOPHILUS DARWINI. 



The next species which I have to describe has been presented to 

 me by Mr. Darwin, with the information that it had been received 

 from the Canary Isles. 



Li a collection of Bats from Madeira, given to me also by Mr. 

 Darwin, I could only enumerate two species, both European, viz. ^S". 

 leisleri and S. marginatus ; and I was somewhat surprised to find in 

 the present species one which I had not before met with. None of 

 the descriptions of African species in the works of Temminck, 

 "Wagner, Peters, Smith, and others, apply to this species ; and I there- 

 fore regard it as new, and describe it as follows : — 



It is one of the same group as the species just described, and as 

 the S. huhlii and 8. pipistrellus of Europe. It is characterized by 

 a somewhat more robust make than these species, and has rather 

 broader ears and tragi. 



The head is rather broad and flat, the crown being but little 

 raised above the facial line ; the glands of the lips are considerably 

 developed, and bulge sufficiently to occasion the nostrils to open 

 nearly straight forward, although the interruption in the outer mar- 

 gins of the latter sufficiently indicates that with a more pointed
