sors are four-lobed, and that in the upper jaw one more 

 premolar tooth is found inserted, of so small a size that 

 it is difficult to discover its place, which is close to the canine 

 tooth ; in this respect it reminds one of Molussus Australis 

 (Gray). 



Should this species now before the Philosophical Institute 

 he a previously undescribed one, allow me to name it after 

 our respected President, Vespertilio Muelleri.

 I am sensible, in touching upon their particular department

 Whilst, however, I apologise for my temerity in submitting 

 my views on these heads, I may add, that on one other point 

 on which I have chosen to express an opinion — the financial 

 — I may, perhaps, without egotism, claim to be, at least, on 

 a par with most members present. Nevertheless, I wish it to 

 be distinctly ^understood, that even on this point I express my
