The type specimen of this shell was said by Reeve 

 to be taken in Tasmania, and is now, according to 

 Tate and May, in the British Museum. Bednall, in Proc. 

 Mai. Soc, London, Pail 4, April, 1897, p. 141, describes 

 it as "a small elongated species, ornamented dorsally with 

 fine, longitudinal, microscopically — closely — beaded riblets, 

 which become coarser and somewhat divergent on the 

 side slopes and with the terminal and lateral areas con- 

 centrically sulcate, the lateral areas especially so." 



Some large specimens, length 16 m.m., breadth 7 

 m.m., were dredged bv W. L. Mav from fifteen fathoms 

 in Geographe Strait, East Coast of Tasmania. Smaller 

 specimens were dredged in nine fathoms off Pilot Station, 

 River Dei-went. No specimen, to our knowledge, has been 

 taken near the shore. 



The large specimens dredged show the lateral areas 

 distinctly raised, and have irregular strongly-marked con- 

 centric growth lines, about ten in number.
