Monographia Heliceorum vlventium. Vol. sextum. Auct. Ludovico 

 Pfeififer, Dr. 8vo. 598 pp. Leipzig, 1868. 



This is the second volume of the third supplement to the 

 monograph of Helicidse : — The first, noticed by me recently, 

 contained Helix proper, while the present issue is devoted to 

 Bulimus, Achatina, Pupa, Cylindrella, Clausilia, etc. 



The last issue of the monograph of these genera was in 1859, 

 and I give below the number of species contained in each genus, 

 both of that and the present volume, in order to exhibit the pro- 

 digious advance of our knowledge of these genera during ten 

 years.
