i02 PETT!ERD : ON TASMANIAN MARINE SHELLS. 



NEW SPECIES OF TASMANIAN MARINE SHELLS. 

 By W. F. PETTERD. 



In the ' Proceedings of the Royal Society of Tasmania ' the 

 Rev. Mr. Woods has described a large number of new species of 

 marine shells, including over 60 species from my collection, and 

 subsequently the same gentleman compiled a census of the 

 species known up to that time. Although of such recent date I 

 have already met with several new species, the majority of which 

 I now describe. The species do not present any very noticeable 

 departure from the already recorded forms peculiar to this island. 

 The most worthy of special notice is a new Schismope, very differ- 

 ent from the other Tasmanian species described by Mr. Woods 

 as S. Atkinsoni, and a species of Tornateila, a genus heretofore not 

 known to exist here, and although of very small size is worthy, on 

 that account, of notice. 



There is little doubt that much remains to be done in the 

 marine shells of the island, and as dredging researches proceed, 

 our knowledge will thereby be much augmented, and it will in all 

 probability be found that our present knowledge gives but a scant 

 idea of the moUusca of this province. 



In future numbers of this journal I hope to have the pleasure 

 of bringing under the notice of its readers much additional in- 

 formation respecting the described species, and notices of those 

 that I may meet with that are not recorded.
