considered as a distinct species ; it may, however, be the same as E. littori- 
noides, Reeve. I have collected at Lyttelton a single living specimen of F. 
striata, Hutton (Trans. N.Z. Inst., vii., p. 458), and find that its denti- 
tion exactly resembles that of E. lineata here figured, the shell is quite 
colourless, but the animal is spotted with maroon brown.

This species has usually been put into Purpura, but its operculum is 
sufficient to remove it from that genus, and the aperture has no posterior 
canal. :
