In conclusion, we must observe, that the specific characters are 
often far longer than is desirable ; that in making alterations in the 
nomenclature, the author has in some cases not sufficiently pointed 
out the reasons which have induced him to adopt different names 
from those employed by Smith and Hooker ; we must, however, add, 
that in most instances we are acquainted with causes fully author- 
izing the change. A more frequent reference to foreign authors 
would also have added much to the value of the book. 
We must again express a hope that this work will soon be in the 
hands of all British botanists.

ZOOLOGICAL SOCIETY. 
January 14, 1840.—William Yarrell, Esq., V.P., in the Chair. 
Mr. Ogilby exhibited the skull of the Mangabay Monkey (Cerco- 
pithecus Aithiops, Auct.), and called the attention of the members 
present to the fact that this species, like the C. fuliginosus, differs 
from other Cercopitheci in possessing a fifth tubercle to the last 
molar of the lower jaw. 
A variety of the common Hare (Lepus timidus, Auct.), shot in 
Sussex, and presented to the Society by Augustus E. Fuller, Esq., 
* [The Bulla here described is only a variety of Bulla Velum, which often 
has one, two, or three white bands.—J. E. Gray. ]
