An imperforate trochiform conical shell with an obtuse vertex ; 

 white with a broad red band, which is wanting inside, about an 

 inch high and 10 lines in diameter. This shell is said in one 

 place to come from Macassar, and in another from the East 

 Indies ; but it is evidently a common widespi'ead species, well- 

 known to many earlier conchologists.

This widely distributed and well-known shell has been described 

 by all the ancient conchologists as far back as Lister, and, strange 

 to say, for a species which varies a good deal, has not many 

 synonyms. It is an umbilicate shell, oi'bicularly convex, with an 

 obtuse spire ; yellowish with a brown band, or with a white band 

 or two, or a purple band joined to a white one ; with vai'ieties in 

 which the band is red, yellow, white, blackish, and even yellowish- 

 green. This band of colour seems to divide the shell into an upper 

 and lower portion. There are excellent figures of the animal 

 in the " Voyage de I'Astrolabe," pi. 11, figs. 1-4. 



It is very common through the islands of the whole Archipelago 

 and the Malay Peninsula.
