MOLLUSCA, WITH DESCRIPTIONS OF 



NEW SPECIES.

Plates I.-VIII. 



A visit by the writer to the Furneaux Group in Novem- 

 ber, 1912, resulted in the addition of several species to our 

 list,* and careful investigations in Port Arthur and D'En- 

 trecasteaux Channel have largely increased our knowledge 

 of our Chiton fauna, adding new species and extending the 

 distribution of others. 



The dredging operations in connection with the two last 

 Easter camps of the Field Naturalists' Club at Safety Cove 

 and Thouin or Wineglass Bay, have also added a number 

 of interesting species. These localities are respectively the 

 most northern and most southern spots at which deep-water 

 dredging has been carried out in Tasmania. 



It is proposed in this paper to give a list of the additions, 

 to record certain facts respecting distribution, and to de- 

 scribe 40 species which appear to be new to science. The 

 types of these last will be placed in the Tasmanian 

 Museum collection. Altogether I here add nearly a hun- 

 dred species to our list. May, 1915.
