emargination pretty strongly marked. The right lip is a little 
dilated and sharp ; within striated, and of a reddish brown, as 
well as the columella, which is straight and somewhat twisted 
at its base. 
Length 14 lines. Width 6 lines. 
Inhabits the port of King George, in New Holland. 
The form, and particularly the color of this shell, are quite 
variable. Quoy and Gaimard, who established this species, 
mention several varieties, one of which, smaller, is found at the 
Bay of the Isles, at New Zealand (Voyage de l Astrolabe, pl. 
30, fig. 14-16); they have given another in the same work, 
pl. 30, fig. 19-20; they have, besides, noticed: two other varie- 
ties of this shell, one of which, also smaller, has a reddish 
ground, with spiral brown bands upon the sutures; the other 
has distant and well marked transverse strie. We give, of this 
species, pl. XI, fig. 37, a variety which has a narrower elongated 
aperture, and which is covered with more or less oblong spots, 
with a band of a bluish color covering the middle of the lowest 
whirl.
