708 MUREX. 



Shell about an inch and a half long, and an inch and a quarter 

 broad, and the spire somewhat produced and turbinated ; the 

 colour is white, variegated with black, and the throat smooth, 

 and whitish with brownish yellow stripes. The shell, which 

 Born has described under the name of M. Hippocastanunij 

 probably belongs to M. calcaratus. 



NODATUS. 52. Shell ovate, transversely striated, 

 with four rows of compressed spines ; outer 

 lip toothed within, and the pillar slightly 

 plaited.

Inhabits the coasts of New Holland. Martyn. 



Shell about an inch and a half long, and rather more than half 

 as broad, of a greyish white colour'; it has four rows of 

 compressed nodulous spines on the body-whirl, and one on 

 the spire ; the outer lip is rather strongly toothed at a small 

 distance from the inner margin, and the pillar has two some- 

 what obsolete plaits. 



LACERUs. 53. Shell ovate, transversely striated, 

 and armed with two rows of compressed 

 spines ; spire muricated, and the whirls 

 keeled.

Inhabits the coasts of Guinea. Martini. 



Shell an inch and a half, or two inches long, and about two- 

 thirds as broad, and has two transverse rows of rather remote 

 compressed pointed nodules on the body-whirl ; the spire 

 consists of five carinated whirls, and the keel is somewhat 

 spinous ; it is sometimes of a pale rose-colour, and some- 

 times brownish. Gmelin, with a mark of doubt, has referred 

 to Martini's figures of this species for M. Hippocastanum. 



PLICATUS. 54. Shell ovate, ventricose, with the 

 whirls lon'gitudinally plaited and striated 

 transversely ; throat violet.
