 Inhabits the coasts of the Mauritius. Chemnitz. 

 Shell about an inch and a half long, and equally broad ; it is of 

 a pale chestnut-colour, with a white band across the middle 

 of the body- whirl, and also at the suture and along the out- 

 side of the inner lip ; the throat has two reddish stripes ; 

 the umbilicus is said to be deep and spiral, but no mention 

 is made of its being bifid, and in this respect it appears 

 principally to differ from N. rufa. N. leucozonias is not 

 well defined, but from the description and Kzemmerer's 

 figure, it appears to be at most only a Variety of this species. 



RUFA. 7. Shell sub-globular, smooth, of a reddish 

 brown colour, with a white band at the su- 

 ture ; umbilicus bifid.
