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 MtMops, 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.]
