Of an oval and rather irregular form, with the spire hidden and 

 the lips of the aperture raised beyond it; the columella lip is 

 tumid, at the apex raised into a varix, in the centre swelling so as 

 to form a ventricose outline and anteriorly raised into a sort of 

 blunt tooth ; it has irregular plaits on the pillar. The outer lip 

 is denticulated within and neatly marginated without. In colouring 

 there are many varieties, but all are marked with more or less 

 interrupted transverse lines. 



From Demerara.
