An impei’forate 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 widespread 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, orbicularly convex, with an 
obtuse spire ; yellowish with a brown baud, or with a white band 
or two, or a purple band joined to a white one ; with varieties in 
which the band is red, yellow, white, blackish, and even yellowisli- 
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 TAstrolabe,” pi. 11, figs. 1-4. 
It is very common through the islands of the whole Archqielago 
and the Malay Peninsula.
