380 APPENDIX. 



A very inconspicuous ordinary-looking little shell, its 

 upper surface recalling the aspect of H. alliaria but with 

 more convexity and no lustre,, and its base that of H. crys- 

 tallina. It was found, apparently gregarious, under dead 

 leaves in an islet in Trinity Bay.

This very remarkable shell, the first of its genus dis- 

 covered in Australia, difi^ers from all its congeners. It has 

 exactly the aspect of a Clausilia, but the mouth is not 

 furnished with a clausium. It was found under stones at 

 Port MoUe.

This, the giant of its genus, is perhaps the most remark- 

 able land shell discovered during the voyage. It differs 

 from all other Pupince in having an unpolished surface. 

 It was found in the South -East Island of the Louisiade
