THE PULYPLACOPHORA OF TASMANIA. 



By W. L. May and W. G. Torr, LL.D., Etc. 



(Read May 13, 1912.) 



PI. I. 



Recent dredgings and other excursions in connection 

 with the Tasnianian Field Naturalists Club, but more 

 particularly an extensive examination of the North-West 

 Coast by W. G. Torr, have introduced us to many species 

 not previously known from Tasmania. In addition, much 

 knowledge has been acquirea respecting the distribution 

 of forms already recorded, so that the time seemed oppor- 

 tune to bring out a new and up-to-date list, which we be- 

 lieve will be of distinct value to students of this in- 

 teresting group. We have here increased the Tasmanian 

 list to 32 species, including two new ones. It will 

 be noticed that on comparing our list with previous ones, 

 several names disappear, either because we consider there 

 was a wrong identification, or because we cannot con- 

 firm the record, believing that a mistake was made.
