Tornatellina dentata Pease, P. Zool. Soc. London, 1871, p. 460. 



I identify Mr Perkins' specimens with some doubt ; if not this species they 

 belong to no other recorded Hawaiian form.

Not found by Mr Perkins ; I have specimens from another source, without indica- 

 tion as to which island they come from.

A single shell, found by Mr Perkins, agrees well with Pease's description and 

 measurements, save that Pease speaks of the shell being sometimes spirally sulcate, 

 while Mr Perkins' specimen shews traces of a single spiral thread at the periphery. 



Hab. Kauai (Pease).—.'' Hawaii, Kona at 3000 feet (Perkins).
