PREFACE. 



Since the publication of my Catalogue of Australian Land 

 Shells in 1864, numerous new species have been added to 

 the Australian Fauna described by Pfeiffer, Morelet, 

 Adams, Angas, myself, and other authors, many of the 

 typical species of which are in the collection of the Aus- 

 tralian Museum, in my own, and other private collections 

 in the Colony. To enable Conchologists to correctly dis- 

 tinguish the newly described species, and to prevent an 

 accumulation of synonyms, I have undertaken to give a 

 synopsis in this Monograph of all known Australian Land 

 Shells, with their full descriptions ; figuring as far as lies 

 in my power all well-defined species in XVIII plates. I 

 hope soon to be in a position to supplement these, as 

 several new and valuable specimens have very recently 

 been added to my collection. 



For the habitats given, I am much indebted to my late 

 friend, Mr. John MacGillivrat, Mr. Masters, the Eev. E. 

 L. King, Mr. F. A. Blackman, Mr. Blomfield, Captain 

 Edwards, and other friends on whose authority the 

 strictest reliance can be placed. 



The Illustrations, kindly executed for me by Miss Scott 

 and Mrs. Edward Forde, speak for themselves, and I have 

 no doubt will be duly appreciated by the public.
