 with Paraclathurellri , but Smith, who better appreciated the real relation- 

 ship of Hemiclaphne, remarked ^^ on the difference of the apex.

The Australian shell is 10 mm. long, and therefore considerably larger 

 than the type, which is o)ily 7 mm. long; but judging from literature, 

 this form may be counted as a variety of the species of Desliayes. To 

 facilitate recognition it is here figured. 



Hah. Queensland: — Murray Island and Mast Head Island (self).
