Hah. Common in rock-pools at Green Point, Watson Bay, Port 

 Jackson, N. S. Wales ; also Parsley Bay, Port Jackson {Brazier). 



Althons;li of small size, the specimens described are evidently 

 adult. Tlie species is remarkable for its produced acuminate spire, 

 the deep chestnut aperture bordered with a yellow outer lip, the 

 almost black colnmella, and the red and white punctate character 

 of the markings. This spotting is hardly visible to the naked eye, 

 and excepting under a lens the shell has a general dark slaty 

 appearance, yellowish at the suture and the base of the body- 

 whorl.

 above.
