,,This interesting little shell is of somewhat doubtful genus. It may prove to be of 

 the genus Tornatellina or Elasmatina. Its very variable characters render a decision diffi- 

 cult. But it belongs to the old genus Pupa, where J at present place it."

 naria) peponum." 



Sykes, Fauna Moll. pag. 382, Nro. 1 1 : ,, Gould has undoubtedly confused three 

 species under this name ; which is therefore becomes necessary to restrict to one of his 

 forms. J proposc that it should be used for the shell figured by him as Fig. 104 and 

 Fig. io4d; namely the slender species with a parietal lamina and no columellar tooth ; of 

 this J have Hawaiian specimens. 



The next form, that figured as Figs. 104 a — c, has no parietal lamina, and equally no 

 teeth on the columella; this has becn found by Mr. I^erkins on Kauai, and is here named 

 T. confusa. 



The third form, figured as Fig. 1046 (enlargement of mouth only) is a shell nearly 

 related to T. euryomphala Ancey; it is not, J think, T. newcombi."
