MOLLUSCA. 



By EDGAE a. smith, F.Z.S., of the Zoological Department, British Museum. 



The four following excellent plates will be very acceptable to Conchologists, as they contain figures of several 

 species (about twenty) which, until the present time, have been known only by descriptions, in some instances very 

 short and insufficient, and also the more interesting as, in thirty-one instances, the actual type specimens are de- 

 lineated. 



Plates 1 to 3 are devoted exclusively to species belonging to the New Zealand fauna. Four of them are new to 

 science, and three, described some years since, are unrecorded in Von Martens' very useful " Critical List of the 

 Mollusca of New Zealand." 



Plate 4 includes, with one exception {Helix Mcnlemw), figures of some Australian Land and Freshwater Mollusca 

 of which two appear to be as yet undescrilied. 



All the species with the exception of Bidimus antvpodum and Vermttvs cariiiifenis are in the British Museum, 

 and those preceded by a * were presented by Sir John Eichardson, M.D., F.E.S.
