GENUS BUCCINUM. 3] 



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, duoy 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 F Astrolabe, pi. 

 30, fig. 14-16) ; they have given another in the same work, 

 pi. 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 striae. We give, of this 

 species, pi. 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.
